Re: ThinkPad L13 Gen 2 i5-1135G - smartbeeps 011000 & shuts down - worth a repair?

if someone looks for that issue, this code was resolved by reballing on-board RAM. Device was posting with one of chips hardly pressed on board(dont do that in chassey, put board on flat firm surface).
it is pain in the ass, so if it is not economically viable in your repair, you can try reflowing it instead. it uses 138C solder, so do not overheat the board and use low temp flux.

Re: iMac 27" 5K 2017 bios dump needed

this thread helped me (not) finding the bios. great job asking for bios and not sharing it after you found it.

macbook pro 2018 with a touchbar. since waterdamage rework did not help, i need some clue what could cause SSD malfunction.

Re: Lenovo 500-15isk - Charging/Power problem

So I fixed this board today. after checking chip voltages i found that VCC drops from 19v to 3.1v on one tiny resistor which looked more like a fuse. i googled a little bit and found the same exact problem with the same exact symptoms on some Russian forum. I decided to short this resistor and it really worked. It was a 10om resistor, and i replaced it with a tiny copper wire.

even though i could not find this board schematics anywhere, chip datasheet really helped me to troubleshoot this issue....

Hello everyone.
I am new here, and i am new in the industry(i started to work in a local repair shop a few weeks ago).
I have a laptop Lenovo 500-15isk with the following symptoms:
starts with the battery, do not charge|does not see DC adapter.
without battery turns on for a second, then shuts down. Amp consumption hits 0.5A then goes back to fluctuation 0.1..0.2 with a tiny noise near the charging circuit.
Could not find schematics diagram and i also do not have enough experience to find all control voltages without it.

I would appreciate any clues...

Hello everyone!
My name is Alexey, I am a former cellist, trying to learn board repair while working in local PC repair shop in Munchen. To my surprise, nobody makes it here, especially for normal laptop motherboards. people just buy a new device even if it worth changing something inside. However, i have already repaired few bad caps (literally) and learning with youtube videos every day.

I also have basic programming skills and a small ferret. I am also a co-developer of "The Polynomial" game...
