C(series) = 1/(1/c1 + 1/c2) => 1/( 1/10 + 1/10 ) => 1/ (1/5 ) => 5uF, but yes, the voltage rating adds up. Hope I didn't come across as too much of a jerk there.

Slight correction: if you put 2 10 uf caps in series, you do indeed double the voltage but the effective capcitance is 1/2 or in this case it would be 5 uf.

Your soldering technique isn't as good as Northridge's but your technical knowledge + analytical skills are way above of what I have seen from him. Also your tools are very dedicated to specific problems. I'm rlly thankful to learn from giants like you on youtube. Please keep up the good work.

Well done Graham. Things are never as simple as they seem. Great piece of troubleshooting.

Keep up the good work and thank you for the tutorial. Learning so much from your channel.

These are always informative and frankly entertaining, love these videos

Great video dude!

Great videos as always. Thanks for sharing ur works

Great content like the detailed information you take time to put in Thank you

Graham an absolutely brilliant repair,and exellent fault finding,well done bud,

I'm surprised you didn't check the board as running on its own after the capacitor change. in any case, I'm really enjoying your videos. More please.

Hey spotted my 3d printed case for the bios programmer again glad your still using it 😊

Great video. Thanks for not editing that down. 30-45 min is perfect to really (actually) learn stuff.

15:19 That blade soldering tip can actually reach both side of a simple SMD passive at once if you rest it on the side of the SMD and add a lot of solder, ie, it can desolder both sides at once. It saves melting parts close by.

Watched this for 5 mins and subscribed. You clearly know how to repair system boards on laptops so I'm adding you to my list. (It's a good list..not a bad one).😁 Edit: I liked your analysis of the dodgy battery. I have the same battery analyser you have. I need more time to build a database for what it can test.

One more Thing :), great material thank you for your job.

"Behold my madness" - love it

Thank you for sharing.

I'm no Mac guy but I know what PP Bus G3H is, Louis Rossman's arch enemy.

Sir your accent is very clear easily understandable. always you make Very detailed video 👌👌👌👌 I learn so many things from your videos. 👍👍👍

You need a pair of hot tweezers , also a little flux and low melt solder greatly helps in removing components. All in all great job though , I’m replacing a battery in the same Mac book this week and it’s nice to see how things can go sideways .

I like the video so much. Very educational. Thank you for showing your ups and downs during the work without editing, we learn a lot from watching this. I don't like videos of supermen! Not sure if the change of the capacitor at the beginning were needed? Keep bringing these videos our way :)

Thank you for the great effort to deliver the information to your valued followers. I would like to know where I can get the computer circuit schematics, thanks again.

Great work 👍 You forgot a little drop of solder in the right of the fuse, it can cause problems!

Threw away a Dell Latitude PII-266 some years ago that wouldn't start (no power whatsoever). After watching your videos, I bet it was as simple as a capacitor. Although having far too many computers, I will never forgive myself 😝

Great battery tool like to see more of it, to expensive to buy as hobby fixer.

True, you miss.Spoke about the capacitors and series

I used iFixIt recently to replace a battery in my early 2013 Macbook Pro 15in. Seems good so far after about a month of use. From the US.

You could set up an Amazon list so people can buy you stuff like the tweezers.

After going though the work to connect the NLBA1 to the battery, you were about 2 clicks away from reactiving the BMS and having a good chance to end up with a working battery. Of course some controlled charge-/discharge cycles would have been recommended, but it would have been worth a try instead of throwing away a battery after just 2(!!) cycles.

i have used a lot of egoway batteries bought of ebay uk. they worked great.

NinjaBatt Caution reads "Do not dispose of fire, but keep the battery away from fire.", sounds like babysitting siblings.

I had a motorcycle that "blew" a fuse like that. I was going crazy for a while trying to figure out what was going on. Things were getting voltage and the fuse looked OK and a quick continuity test beeped. Finally after seeing that the ignition module acting weird I checked the resistance on the fuse and just like this, it had resistance. So there wasn't enough current to turn things on. Something I always check now even if a fuse looks good. I didn't know they could do that either but it makes sense if you think about it because the bridge inside the fuse can burn just enough to increase the resistance to where it doesn't burn all the way through and disconnect.

Tip: Get a bend pointing tip for your iron and learn to use it, so you won't spin boards around. You can use bending tip to reach to all angles to components.

I binged maybe 50 of your vids in the last days. Very informative and well made! What I did not find was any dead Thinkpad. I just got a refurbished P53, and the internals look bullet proof. My old W520 runs partly 24/7 for months, no problem whatsoever in 11 years. Any idea if there is a quality difference between Apple, consumer devices and business notebooks regarding electronics?

I'm really not sure. I wasn't able to open it to find out. We wanted to replace these with authentic charger cables. Not sure how it tricks it, but it's quite helpful. Was tired of being told there isn't enough power to turn on the device. This eliminates that issue, and even starts the USB MacBooks with the battery disconnected. If you find out any more info, please let me know. Love the videos.

Hi. Your video is so awesome 😎. My mainboard is dead and it show the same thing of around 20v but no current. My question is if you could fix the mainboard, and how could i send you for fixing? And, how much? I trust you😊. Tks

Hi bro do you have bios dump for asus rog strix hero II gl504gm with gtx 1060 gb? Or dead bord laying in your shop, i have some issues with bios file

where can I check if the battery is slowly charging on a macbook A1502? Cant find any mosfet

after replacing the capacitor, if you would have tried to turn on the PC connected with the adapter, it would have turned on? Then you replaced the battery just because it didnt turn on with the battery, as it locked itself?

Non related to this video but has to do with Video 143 At mark 32:46 in the video what is the the thing called you are plugging the power and rest buttons called to be plugged in the motherboard?

As always great repair video Graham! I have one question; what is the microscope 🔬 you are using?

About the fuse résistance : are you sure 80 is the résistance or the fuse or is it for exemple 30 to the ground from one side plus 50 to the ground from the other side ? What do you think ?

Northridge is using the capacitor book for that. You got something like that too?

What is the name of the solder that you used?

I was wandering how much does a repair like this one cost appr.?

I have hp pavilion g6 - 2288se capslock 2 long blinks problem , how to fix it:(

I'm wondering if the original battery was swapped as a first try and then the job passed on to you.

I learnt another lesson, where do you usually get your capacitors and supplies? Thanks

Can u repair a ASUs locked bios it’s all greyed out if so how do I contact u

I’ll try find my brand of MacBook battery,, it was brilliant. Work brought it so I’ll find where it was

Your haircut looks good

hi. where do you buy Amtech flux? tnx

I've never seen a fuse go high resistance like that. Not that I have much experience with SMD ones, might be something to do with how they're constructed

I've watched lots of vid's you've done and enjoyed them. I have a question and I know it's unrelated to this vid but wondered if you've encountered an Asus laptop 30 minutes timer sudden death issue, well not death, just that it's like the battery or mains ceased to exist yet it boots up again by pressing the power button for another 30 minutes and on the dot same thing happens. I've changed ram, CPU, checked the bios battery/charger you name it. I even re-flashed bios. I've heard something about Intel's ME firmware causing this issue, I have an external USB reader for Bios chip though I have to solder it on for accurate read/write. The laptop works perfectly for 30 minutes laptop in question is Asus x401a i3, I know it's old but I'm not going to throw away a perfectly functional laptop. Any pointers please?

Very helpful video bro..can you plz twll me which boardview software you used here?

My x99 motherboard got problem b7 if i use ram on upper side cpu , or 53 if i use ram on below side cpu , dont know what actually happen 😞

Hello !!!.. One question, I'm fixing a MacBookPro A1707 that buy on ebay heeh.. the thing is that already detected several capacitor dead, and then the laptop start to consume some current. The thing is that after some seconds or minutes, the same go again to "dead state" , 20v - 0 current...... What do you recommend to check?... So far I check on the power aliases for the PBUS rails and I have 12v on all of them, but when checking on IMVP Rails, are at 0v... Is this normal if the CPU has not fully started?.. I'm starting to think in a faulty battery , what do you think recommend to check? Thanks for any suggestion you could provide! Regards,

What make is that capacitor?

It would be great if you can make video regarding battery unlocking. I’m not sure how capable that device is for unlocking.

I'd echo your sentiments on NinjaBatt. Avoided the same Macbook Batt because of reviews though and glad I did now! Also never had any comeback on GreenCell but they seem to come from Poland sometimes and delivery can be a week or so rather than the advertised delivery period.

Not sure if brexit made a difference for UK folks but I'm wondering if there is still an easy way to get some leaded solder in mainland europe, cause I know the EU pretty much banned lead and with that in mind I kind of want to get a lifetime supply of leaded solder while I still can

Dont be afraid to use more flux than you think you need. It will make your life, and soldering much easier.

Nice work as always Graham ! But please, no spoiler in the thumbnail :D For us it's like watching a movie with a plot, we don't want any spoiler :p

I have used greencell batteries and have not had any reliability problems

You could have also used this tool. It enables you to disconnect the battery and still be able to start the MacBook with charger. BY-3200 Mac Power Cable Start Cable Tool

bEST REPAıR VİDEOS FROM YOU KEEP GOİNG !!!

Could the battery have blown up the capacitor?

Ordered NinjaBatt brand before. IME, worked OK for first few months then capacity nosedives. Not the worst but not recommended either. Quality cells actually cost $ to manf, whooda thunk.?

The new mouse pad is not ready for serious work until you burn the first of many holes in it.

Two 10mfd capacitors in series results in 5mfd.

55 years of electronics and I have never seen a fuse that was not zero or infinite ohms.

Unlock the batt and keep it as a tester

Where did you get your UK Amtech flux from? i'm still recovering from the smell of the fake stuff i got from ebay :(

Please provide the link to buy flux in UK.

hi, i love your videos, really helps a lot. maybe you would be so kind to assist me. i have a bricked gigabyte p17 v3 with the wrong bios and i am trying to reprogram it with a ch341a. now i followed your steps and advice as close as possible. my problem is that i cannot find a bios bin file for the chip (gd25b64csig) or i am just too ignorant. can you please assist me.

Take this UNHAPPY Capacitor off the board! He looks GUILTY as heck!

"sensitive data" = lots of porn 😂

Why didn't you unlock the battery it's only has 4 cycle count Didn't you see sorin how he use the battery analyzer tool

Which screw driver is best for opening any MacBook and which brand screw driver do you use

👍👍👍👍👍

Please enable subtitle option

Is the client using an original charger? It's all very fishy, this laptop has gone through 3 batteries...

Could we just take a moment and acknowledge, that 0805 capacitors with 22uF and 25V should not exist? Whether it's an old Macbook, a new Macbook, a Lenovo thinkpad, a Lenovo dockingstation, an Dell Laptop - these things are becoming a running gag and not a very good one at that. Apparently they can be manufatured with that kind of spec, but with 0 tolerance and thus only with a very low reliability.

When I sent my MBP A1706 to a place to be fixed they said it’s shorted through CPU. I refuse to believe them. They couldn’t fix it, It’s still dead ☹️

Hello Interwebs

2 x 10uF caps in series would give you 5uF!! Also all that scrubbing from side to side with the soldering iron tip is a very bad idea IMHO. You run a very high risk of detaching the pad by overheating in combination with mechanical force.

0-5 ohms on a fuse is ok.
