Good thing that they changed the design back.

I agree. Sincere thanks for your answer. Removing the Connectors as done here is absolutely fine. If I want to be sure, I use a single wire with double alligator terminals. One alligator direct to ground (screw hole) and on the other alligator add any 1W [1 - 15] ohm resistor to touch each individual pin. Damaged test terminals (power supply or a multimeter), previously measuring the continuity of the wire to be used, serve this purpose. On the other hand, already skirting the limits of exaggeration; I cover with black or kapton tape the cable that goes to the screen and also the connector on the motherboard. I do this to any laptop. All the best.

or battery...? :P

@@RWL2012 Toast :P

Any kind of operation on the laptop needs the battery disconnected really, its kinda SOP and a good habit to make sure. 🙂

Interesting! A lot of overengineering purely for the sake of being able to hot-swap batteries it seems. I've never heard of anyone who's actually _needed_ to be able to hot-swap a battery though.

thanks for tip, I strongly recommend this to people if water is spilled on PC. Then right away enable "battery disable" this helps prevent further electrical corrosion. Cool

big mood 😩

@@Adamant_IT I remember the first time I had to replace a keyboard on a Thinkpad X240. I had to strip down the laptop completely... I think Lenovo has frustrated designers 😁

@@brecht4713 Why? There's always a Thinkpad HMM (Hardware Maintenance Manual) with all the Steps. The Keyboard should be easy. Look at the underside of the Thinkpad. There should be 2 or mor screws with a keyboard symbol. Take this out and then it's only a simple push in direction of the screen and the keyboard is free.

@@rainerbehrendt9330 That is exactly what I did. Believe me, for the X240 you have to remove everything to replace the keyboard. Look it up if you want 😉

I stand corrected. Sorry. Took a quick look into the X240 HMM. For access, remove the following FRUs in order: • “1010 External battery pack” on page 59 • “1020 Base cover assembly” on page 59 • “1030 Internal battery pack” on page 60 • “1040 Memory module” on page 62 • “1050 Hard disk drive or solid-state drive and drive cable” on page 62 • “1060 Wireless-LAN card” on page 65 • “1070 Wireless-WAN card or M.2 solid-state drive” on page 66 • “1120 Speaker assembly” on page 74 • “1110 Coin-cell battery” on page 73 • “1080 Fan assembly” on page 67 and two more steps. This is crazy. Not comparable to the T or P Series i own or owned.

I'll keep an eye out for those rubber tabs if I see one of these again! I've actually seen one of these before a long time ago, and don't remember having so much trouble with the keyboard. I figured this one was just stiff or something.

NOPE, cos if they did that, customers would replace the fuse, it goes bang and they then put a bigger one in or a shorting link across it. Then they bring it to a repairer and say "dunno what's wrong wiv it, it just stopped". Repairer has a ten times more difficult job to fix it. Been there, got the Tee Shirt, book, badge and plenty of kit that customers "broke" trying to repair it themselves. That's why they put labels on like "NO CONSUMER REPAIRABLE PARTS INSIDE". If it can't be fixed by turning it off and on again, leave it to the experts like Graham.

@@ChasLarge Exactly this ^^ 🤣🤣

@@ChasLarge Yep good point CIL...hadn't thought of that ...you are of course correct

@@cattflap1447 yep Furry you are both right

I use 7zip

I only recently found out that the never expiring free trial is because of companies that are only allowed to have paid software!

I agree, they later changed back to a better design, but you still have to disable the internal battery thru the bios before working on these machines.

The T440p is different from the T440 & T440s. The T440p only has 2 or 4 screws that are revealed when the keyboard "cover" is slide up to expose them. The back cover is a dream to remove with only 2 screws holding it in. Just remember to slide the back cover off the clips. Being used to earlier Lenovos I went and pried the cover off and broke 13 clips in the process. Fortunately Lenovo were very good and replace the AUD$103 back cover under warranty. 🤫

@@josephking6515 I have already T440p, this laptop is really great for upgrading. Now my T440p has FHD IPS display, 16GB RAM, i7-4702MQ and 2nd drive in DVD drive bay. If we can compare stricte cpu performance, this i7 is comparable to i7 8. gen, for me it`s a beast. I want to buy eGPU but WLAN/WWAN white list block eGPU adapter and i have to modify bios dump.

Best thing to do is isolate it by disconnecting it physically. Never rely on software to isolate power from a physical device.

@@IIGrayfoxII Yes , cant beat breaking the physical connection

Though I feel bad for the guy who did this without knowing that there was a 2nd battery in the laptop that he had to disconnect as well. :( From Graham's perspective, I agree, very poor design for serviceability.

@@gxc90 I have not worked on laptops in years, but quickly saw that the the unit had an internal battery. The internal battery did not look like a random bit of hardware a laptop would have(even a business based one), the connector on it looked like it could handle some amps. It looked like a typical internal battery. I also tend to look at labels of hardware to know what it is.

Correct, yes

Sounds interesting, but sounds like a DIY bodge... useful for someone with no tools, but easily outclassed with any other soldering equipment. I haven't looked into it at all though, so I'm guessing here...

Thomas Hood - Piano Intro I think it's Piano Intro, not in front of my editing PC atm. It's from the _All Because Of You_ EP, but Thomas' old stuff is very difficult to find and link to now. I obtained permission to use it a long while back. The EP is on his old Sound Cloud here: soundcloud.com/thomashoodoldaccount/sets/allbecauseofyouep But annoyingly the piano intro track is missing.

Fuses are non-polarised, so work any way up. They're just a bit of wire after all, albeit a bit of wire that's designed to break under specific conditions. Capacitors it depends. MLCC, the little brown guys, are also non-polarised and go in any way. However, you also get polarised capacitors which have a positive terminal. They're generally the bigger bois, and are marked with a + or a Line at one end.

If by upside down you mean + to ground and - to power Yes and No Polarity matters on diodes and on electrolytic capacitors. Otherwise polarity does not matter on a fuse, resistor or a non electrolytic capacitor. If unsure, match polarity. But if you mean have the component physically upside down on the PCB. It wont hurt assuming the top of the component has the metal tab for solder to make a connection against.

flux, for adhesion, cleaning and soldering.

These sliding bezels are only a good idea as long as there is nothing interfering or sticking. Otherwise they are an absolute pain.

@@anshadedavana thank you for your answer 1 - yes there's a resistor on the rail BKLT_EN it has 0.5♎ it's not faulty AND EVEN 19V comes until the LCD connector 2 - yup Compaq 610 doesn't have CCFL Maybe it's a problem caused by the components on the screen itself

Yes, do your research prior to servicing these units.

You have just fixed one of these . Can you answer a question for me . Does it show two batteries on the taskbar ?? O.k , found it , you have to go to the taskbar and expand it then it shows both as battery 1 and battery 2 . Few people have had issues with it just showing one after a windows 10 update , maybe thats why the previous repair person thought it was dead

@@MrTarmonbarry just saw this comment sorry. i also had to figure out the dual battery thing.

Same

Yea I really want Miniware or Pine64 or someone like that to make some nice affordable ones. I don't fancy the cost of some decent ones that I'll hardly use, and the last time I tried buying cheap ones they were just terrible.

T450s came with IPS touch.

Have you never replaced the keyboard on it?

@@josephking6515 Not yet , over the 5 years of owning this laptop , the repairs and maintenance i've done is repasting the laptop , cleaning and RAM upgrade. Battery was just busted this year 2021. As for the keyboard , none of the keys so far have been acting weird, i clean under the keys to remove some of the dust accumulated using a very light, dry and used paintbrush.
