As others already commented it's absolutely a moron who designed the placement of the battery. The battery has it's lifetime. Maybe you should just throw out the computer after 3 or 4 years when the battery dies. Absolutely insane. I will not go for an Acer again after this.

@ fayyaz6 For some reason I can't reply to your comment. I am sure there is plenty I can't do, but I'll have a go at most things. Thanks for the comment

I actually started laughing half way through this as I simply could not believe how many more screws and connectors had to be removed before you were going to get to the CMOS battery. Man, you sure have got some practical skills up your sleeves. Did you ever work in the IT industry or did you just think you'd have a go one day? I sure would love to see what happens if some others try this .... LOL. I wouldn't try it in a million years but I absolutely have to take my hat off to you Chez. That was one heck of an achievement. Bravo my friend!!!!!!!!!!!!

Great intructional video, but don't waste your time and risk your laptop because of the stupid cmos battery. Changed mine today in 2 minutes. Get a battery + cable and just unplug the old battery left of the HD slot, plug in the new one and place it on top of the HD, fits perfectly and works. The old battery remains unplugged inside.

Shortcut: 1. Follow these instructions up to 1:26 2. At that point, look next to the hard drive on the left. The connector for the battery is visible on the bottom left end of the hard drive bay. 3. Unplug the connector. 4. Gently tug on the wires until the battery comes unglued. 5. Remove just enough screws from that corner to pry open the side and grab the battery with some needle-nose pliers. 6. Continue at 13:16.

I did that that in just 2 minutes! At 17:24 white connector is visible on the very top into the harddisk tray. How to do: Just screw on the back open and remove the cover, like shown in this brilliant video until 1:28. Unplug white connector you find into the harddisk tray (look 17:24 for it at the very top of harddisk trays, it is white, very good visible there) and plug new battery in. Leave old battery inside if its not leaking. Connect new battery, leave it in Harddisk tray or isolate it and route it towards center of Laptop and glue it down. Like that it will be a 2 minutes job. Ultimeate Handyman, brilliant video. If you really need to get out old leaking battery, this is the way to go in easy, well explained steps. Loved it!! Thank you!

thanks for the video, it helped me deciding NOT to change the battery. who in a sane state of mind at Acer decided to hide the cmos battery in such a way?

Thank you very much for the detailed showings. Not one screw and not one cable left over ;-) The notebook runs fine after the operation. This was the best repair-video I have ever seen.

Hi, I had the same issue and ran into your tutorial. Great stuff! Amazing that you have to dissasemble the whole laptop. However, I did not want to do that, and found a shortcut. Next to the harddrive is the connector for the CMOS battery. Simply cut the wire there but leave about half an inch of wire on the connector. Use a CR2032 with a long wire and solder the connector to that long wire. Isolate the cut wires to the CMOS battery with a drop of glue or silicone. isolate the soldered wires with tape. I placed the CR2032 in a piece of foam. The whole fits perfectly in the area next to the WIFI board. A 15 minute job.

It was easy to reproduce your way to change the battery. When the whole computer was splitted apart I was affraid I would not be able to put it back so that it would work again, but the whole thing went perfect at the fist time. Thanks a lot, I was mad putting the date again everytime I was starting my computer.

The CMOS battery is under the motherboard for Z5700 for some crazy reason. You have to undo the heatsink fans and all the screws for the MB to get at it. Undo some screws and lift the MB just enough to replace the battery that's under a bit of black tape. It's not easy but very doable if you know what you're doing. I did it and now it's running fine again.

You do not need to dissemble the laptop to change the bios battery on this model laptop unless you have two hard drives installed. First take your HD out & place in HD slot two & then you can see in the left hand corner of HD bay one the connector cable that plugs the bios battery into the board , unplug & plug yours in the socket & use double sided sticky tape to fix the bios battery down. So easy !

Hi, thanks for the video... but there is other method and more easy. Only you need to remove the lid as you did. The battery is hidden, but accesible. You have to reach it with twizzers. And then, you replace the battery. Put the cover again... and that's it. My college has made this in only 5 minutes. We watched your video and think it will take minimun an hour.

Some Acer laptops have rechargeable CMOS batteries so I think you should mention a bit about that too. Instead of taking my Acer Travelmate 8200 apart to get at the RTC CMOS battery, I looked at some photos of the mainboard layout to make sure I could do what I had in mind, then I measured, marked, and cut out a hole in the bottom of the laptop with a box cutter right over where the battery and connector is located......LOL.. It's 8 1/2 years old so no worries about voiding my warranty. It took me about 30 minutes. It worked perfectly for getting at the battery. When I was done, I covered up the hole with duct tape. Who looks at the bottom anyway? They should have built a door on the bottom right over top of the CMOS Battery.....but I guess they expected the laptop to burn out before the battery.

Simply shocking, if I take my old Acer Aspire 1690 to a technician to replace the backup battery, he will charge me at least 50 Dollars... Congratulations for the great work. Putting a door under the notebook to quickly access the battery was too simple for Acer's designers...

Wow, I didn't know whether to laugh or cry when I got a little way into this. Luckily, I have the smaller Acer 6920G. After removing the small backplate (6 screws) the battery connector is visible, with the battery mostly hidden. I disconnected it and tugged carefully, and after a while the battery and its sticky pad came free. Like you, I didn't have a CR2032-WRS to hand, but I did have a BR2032 (a slightly longer life CR2032), and I got the connectors to stay in place with a paper clip wrapped tightly in non conducting tape! It worked, so thankfully I didn't have to do what you did, but it's a great video anyway.

Yowza! Just spent a couple of days updating and cleaning viruses from my friend's Acer Aspire 9410 and knew the CMOS battery was dead (date/time wouldn't change). I found your video. You did a fabulous job, and you make it look so easy! I've decided to leave well enough alone--I was exhausted just from watching! LOL! Thanks for your great video!

Spent the entire evening following this video. Glad I didn't watch it first! Fortunately had a DR2032 in the house. Just pulled the old wires off the old battery and taped them to the new one. Only three screws left over when I put it all back together. Today my fingers are still sore but the date on my Acer is now correct - hooray! So many other problems with the computer so thought I had nothing to loose - black screen, certificate error on all websites and Microsoft can't recognise my kosher copy of Windows 7 Ultimate so get no updates. Thank you so much Ultimate Handyman xxx PS I am 61 and female!

That's insane! From now on, I'll always look for some videos about replacing CMOS batteries on a laptop BEFORE deciding for which laptop to buy... We might be stupid. Yeah, they can make us feel like that... but only once.

Im glad my ancient aspire was a cinch to change the cmos. In comparison to what youve gone through with that model. Been ten years since I changed the cmos and still works fine. Not to bad for a 12 year old aspire.

Just how difficult do they want to make this task???? I think that they just want you to buy a new laptop instead. Well done mate, good job!

Thank-you. This is the only 8920 cmos install on the net! The instructions are perfect. The closeness of your camera is great because you can really see up close. Great job!

In my opinion there is a short and more simple solution. When the backcover is off you can see the little batteryconnector next to the harddrive bays. Just remove the connector and put the new batteryconnector on it. Leave the battery in the drivebay ( only possible when you use only one harddrive).

Ultimate Handyman: Please pin "Flo.F's" quick-fix description (below) here at the top. Your description is doubtless good and accurate, but hers gets the job done much more simply. I have a failing CMOS on my Acer and I want to take it to a local shop and have them read her description.

Thanks a bunch! Had the unfortunate pleasure to do a replacement of a battery on this monstrosity for a friend. This helped me out immensly (but never again, even if my life depended on it)

Thank you ACER to make a CMOS battery change sooooo complicated and sooooo annoying. Didn't you know that the most often repair on a computer can be the CMOS battery after a change of a HDD or the intallation of new devices ?

This reminds me of the nightmare I had last month replacing the brocken power connector of my MSI notebook, I managed to do it but I think it was more delicate than a brain surgery!

For the Aspire 6390G, only take off the keyboard and pad (unscrew all screw from the bottom side. and under the keyboard the plate.thats it, the CMOS battery is direct on top the Motherboard.No need to unscrew and takeout the DISPLAY and Mother board, dont take out the WiFi, dont take out the Harddisk.

For those who don't want to replace the battery for some reason. You can also "resolve" the problem by automatically syncing your time. This can be done by for example this application: www.timesynctool.com Worked great for my asus. I do appreciate this video!

Holy crap! Having to completely dismantle the laptop to replace a simple CMOS battery is just hilarious and possibly the worst piece of design I have seen in my entire life.

Few days ago, my CMOS battery is out (after more than 10 yrs) and I know how difficult is replacement, but more important things like cleaning of cooler or maintain CPU/GPU are very easy task on this model.

I owned this thing. It must have been designed by De Sade, after an INTENSE romp with Torquemada!

Great video, just the thing I need right now, cause I have a friend's Aspire 8920G here and the cmos battery is dead. I did this once on a HP laptop, it was just as difficult to replace as this one. But thanks for the video, so now I know what is coming onto me ^^

Very impressed with your patience and dedication. Next time try it blindfolded.

Seriously? I have to take apart the whole damn thing just to get to the CMOS battery? This is insane. It's like having to dismantle your entire car just to replace the spark plugs. That's just ridiculous.

Probably will venture into changing the battery based on this video. Wish me luck. Great video by the way.

I went ahead and did this to my pc, and got forgive me, it took me a while to get it right almost 3 assemblies, because when I put it back together I didn't get a signal on the screen... But it would seem that the video cable leading to the screen had gotten a bit worn because it's gnawed at by the hinges... Crappy Acer design... Taped it up and it worked, hell yeah. All that for a bloody battery change :-D Cheers to you for this video Ultimate Handyman!

you can buy thin cr2032 battery holders with connecting wires, you then have to join the battery plug wiring to the replacement battery holder wiring, but a robust longterm solution

It is the hope of the designer that by the time you’ve removed all the screws and cables, your CMOS battery would no longer be a major problem.

A DON`T GO THERE JOB. but with this man on your side =a doddle - just give thought and order with patience -ok so the power button did not work on re-assembly - I forgot to insert the power ribbon. A BRILLIANT INSTRUCTIONAL VIDEO.

I loved the video. Where's the dialect from? We had a lad from school he was from Leigh!. he sounded like you. I'm from Ashton -under-lyne and it was a joy listening to the whole video. This is similar to a video for replacing a fan on an HP we have, which we use to watch itvPlayer and BBC iPlayer, needless to say we just paid a local business to do the replacement.

My God - what a palaver Chez! All that effort to replace an item costing less than 10p...I wouldn't bother - many thanks for the insight.

For Christ's sake, such a complication just to replace a cmos battery. I wouldn't recommend acer laptop then :) Anyway thanks for sharing the video. Thumbs up....

Great video! I have a problem with 8920g laptop showing incorrect time after upgrading to windows 10 but I don't think I am going to attempt to change cmos battery after watching this!

How can you remember where you went all the pieces back in the same place? You are amazing O_O

Wow, you really are the Ultimate Handyman! Great vid chez.

That's ridiculous :-0 still that's Acer for you. If you do another video like this Chez can I suggest an intermission of some sort in the middle? You could do a tap dance or something lol!!

We can all thanks the genius engineers at Acer for this :)

Great video, thank you very much! Incredible effort to change a simple battery...

Unbelievable My Acer 6920 no longer keeps correct time.I have the cmos battery but I'll take it to the repair shop after seeing this. Great video btw.

Thank you very much for this detailed and useful video. I changed my cmos battery successfully :)

Thanks a lot. You saved so much of my time. I now decided to leave the date as it is. Why do they hide that battery so deep inside the laptop? !!!. Thanks again :)

Awesome vid! How do you taped connectors to the new battery? Is it some kind of heat shrink film or something else?

wow, My missis has the famous black screen of death on start up, on a acer aspire 5536, Have done all the usual checks. Its either the bios or motherboard.. You can hear everything working but no screen, Fan slows as you try too boot, Anyway flashing bios from a usb stick, won't work as acer have failed too include to .FD file on my machine type, long… SO cannot flash BIOs a famous fault on this type, another issue is Possible Bios battery Issue.. The things 7 years old, If it takes that long to get into it, I just gonna bin it and buy her a MAC, As an IT tech, I actually tell people to buy them now as WINDOWS, frustrates the hell out of me. But ACer OMG what are you doing lol... You have a hell of a lot of patience, Thanks for the video as it fantastic.

That is a crazy amount of effort to replace a cmos battery, I took another brand apart last week to clean the fan and change the thermal paste on the heat sinks, that merited the effort, but this is just a poor design for such a simple part which by it's very nature will require replacement at some time...

Great video, So much to dismantle for the CMOS battery to be renewed, If ever there was a design flaw this has to be the worst I have seen, As the CMOS battery is connected to the Mother Board by a 2 wired plug, surely the cmos battery could have been located behind an access door under the Laptop, Thus exchanging the cmos battery in 2 minutes, Bad design Acer,,,,.ps I swapped out the cmos battery on my Dell PC in less than 5 mins.

Dissemble entire laptop in order to change cmos battery!!! Acer must be crazy!!! Anyway good video - thks!

Perfect, thank´s for this Video, it was a very great help for me

thanks for great video!!!! Can I replace the original battery with ordinary CR2032 battery??? What voltage must have the original battery? Thanks!

この動画はたいへん役に立ちました。というのは、ＡＣＥＲ　ASPIRE8930G のBATT.交換しようと思っていましたが、諦める決心がつきました。こんな 面倒だとは予想しませんでしたから。普通、キーボード外したらすぐ見える ところにバッテリーがあって、すぐ交換できるのに、、。

Just had a host of repairs done to one purchased from ebay only to find that the battery is dead! Had I known it was dead, I would have let the repairman sort out the battery too after witnessing the drama involved in replacing it!!! I think I will just live with setting the date after every boot. Two questions. I need to replace the DVD drive. Will I need to employ the routine you used up to the point where you slid out the drive? Second, (unrelated) do you know where I can obtain the screensaver and stock wallpaper for this machine? Installed Windows 10, but I'm that type of guy who likes to make laptops look as factory as possible - even with an upgraded OS.

an alternative solution: with a gas burner i heated up the tip of a knife and accurately cut out a 4 mm wide slot in the case right next to the battery plug and pulled out the battery. just don't push the knife too far inside, only a couple of mms.

Bonjour et merci pour cette vidéo. Mais franchement DÉMONTER TOUT L'ORDINATEUR pour changer cette pile, c'est FOU.

I had the same problem - my cmos battery was dead, so i wrote a little piece of program that runs in the background and once every minute takes the time from a special site that supplies this information and sets the computer's clock. of course it's better to replace the battery itself, but as you can see it's not that simple

👋🏼👋🏼👋🏼👋🏼👍🏼 great video. To replace a CMOS battery the trouble you have to go through 😁

Think the morel of this story is don't buy an acer coputer

Every time devil has nothing to do, he designs a laptop lake this. Unfortunately I already own an Aspire 8930, which aside that ENORMOUS disadvantage is excellent.

Hi Took a carpenter knife I cut the hole around - 5min action 😁 Can't post picture in a comment

guys BE AWARE some laptopts/netbooks uses rechargeable batteries so before you attempt this better check your batteries and confirm what you need. DO NOT attempt to recharge a non-rechargeable lithium cell. CR2032 in place of ML2032 is a bad bad idea for example eeepc models uses them. if you are desperate for alternative diy solution u can use tiny li-ion/lipo batteries salvaged from old craps, small gear like bluetooth handsfree headset thingies or similar. just remember not to put it in hot spots inside the laptop/netbook and lower the voltage near 3v. everything will be good. 3v wont be super healthy for lipo cell life and cycles either but will be safe and will work fine anyway. thats what i did.

what a nightmare, acer aspire 5536 i had was same. only thing i did different to you, was i took the opportunity to clean everything up, replace the fan and heatsink and repasted processor. since doing that, and putting windows 7 on, it works as good as its samsung replacement. so much so, that i kept it and ditched my tower

thank you very much! you helped me a lot! without this guide to change the CMOS Battery, i would had lost my mind! soooo many screws and cables to disconnect... i did it step by step with your video and changed it successfully😀 now it works perfectly!

Is there no easier way for this little element to change it? After watching your very good-made tutorial I asking myself if I cannot remove only the volume-touchpad left from the keyboard.

Hello. I changed the battery, it is perfect and the 3.3v reaches the resistor and the diode (BAT54C) without any problem, but however it does not save the configuration when you remove the power. I have changed the resistor, the diode and the capacitor associated with the battery connector, and nothing. Could KBC and/or ICH be the cause of the problem? Thank you.

I did it ! Many, many thanks for your video

Thank you SO much for this video, it's very helpful. Like! I want to replace CMOS battery myself. Tell me, please, is it necessary to wear that blue bracelet to rebuild any equipment? Can i do this without it?

Da pazzi! They are crazy!

After watching this, I'll stick to having the wrong time and date lol

Very impressed

Thank you very very much !!! Hi from Paris

So nice and clear video Thanks

Awesome vid... thanks so much - helped me no end else my laptop would be bricked. Was able to deal with my laptop dead CMOS battery. I have some screen flickering too (many others have reported same) - not sure where that comes from - if you have any insight on the cause I would be most grateful. Most grateful.

have you any idea what could be the reason if this device got stuck and does not boot? i did this nightmare job replacing the battery hoping to help, but did not. i had it running a few days and then only black ... not booting ... everything seems all right, but something is not :(

amazing video did you take a note of where each part was located before hand?

amazing works!

great video!

My laptop doesnt revert back to its manufacturing date but it doesnt keep the time while its powered off. Think its the cmos battery but not fully sure

Darn it! Acer! what were you thinking!????

Thank you for this! i replaced the battery with your help, much appreciated. Question tho, mine is an Aspire 8930g. I had a computer company work on it and install windows ten now surround sound speakers do not work any thoughts on how to fix?

This horror movie :) thanks.

I think I will have to do this with my acer 6920,,,,,,,, will I have to go thru the same procedure as the laptops do look identical???? My clock needs resetting when I turn Laptop on also there are issues with keyboard recognision and a few other issues.

It is called planned obsolescence, or built-in obsolescence (see Wikipedia or alike), I am just struggling replacing the very likely broken CMOS battery on an ACER Extensa 2519. It just says, "no bootable device found", which is very likely to be the broken CMOS battery, usually a cheap CR-2032 battery. Unluckily there are zillions of different ACER models. Making it even harder to find out without ripping everything apart, where the hid this damn thing'? But then most people will get a new cheapo laptop, if it lasts 2-3 years. At least ACER seem the most reliable of all cheapo notebooks available and one can get them without having to pay the M$ tax, as he would want to install Linux anyway. ;-)

My friend has the same laptop and I have a problem install new system on it. When I am try boot anything cd, dvd or boot from usb it turn off and restart. Why this happend ? It is not turning off when I am check HDD by MHDD.

With my 15 year old Aspire 3000, i only have problem storing display brightness level when plugged off. Can replacing cmos battery help?

Insane!

Ok, couple of questions: 1) my sister bought a vaio SVF152A29W model. vaio care program asks to update the BIOS. she updates it, then it prompts to restart. After restarting, she just hears couple of noises from fan, few beeps but nothing on screen and then all silent, then again the sounds and noises mentioned will be looped eternally until the battery is removed and popped back in. 2) can she fix the BIOS by removing the cmos battery? 3) If yes, would you be having any idea how easy it is to reach the cmos battery on the mentioned vaio notebook? 4) she has bought it in UAE 7 months ago and it is still under warranty. 5) but she lives in Sweden right now and the Swedish Sony service center is not accepting the warranty. it will cost her something around 150 pounds to fix it. 6) so do you think removing and putting back the cmos battery will reset and fix the BIOS? Thanks in advance

I have put my laptop in rest mode and the next day it didn't want to boot up the screen was black and when I pressed the power button you could hear it attempted to go on but failed every time. Sometimes it made 3 long beeps and 2 short beeps, I read somewhere on the internet that it could be the CMOS battery so I replaced it. But no still the same... Can someone please help me!?!?

After seeing you fix your lap-top, it wasn't that hard. And I need the part that holds the screen, the lid parts.

i like your video is very good to fix your laptop.i want to fix my laptop and i want to learn about laptop and desktop computer parts,you should make more video about laptop,i am very pround of you.keep up good work.i am very interested about laptop to fix it.keep make more vide about laptop,thank you make this video for me to learn.

***** I have the same problem but with another acer machine (aspire 5552) the CMOS batery is easier to replace than in your video. So following your instructions I bought a new battery, replaced the old one but still have same problem.. any suggestions?

Hi, I am having a problem with my Acer Aspire laptop, it isn't charging properly, I have had it sent off to get repaired but still having the same problem. I have had a look under the case and I can see where the guy has done some soldering. I have my own iron and solder but afraid to damage it if I try to do so myself. I would appreciate it if you could make a video of some sort to show how to safely remove the parts to get to the wires, Thank you.
