Got an HP 1740 with the exact board playman posted the pics on. Need the schematic for 48.L1G02.A01 Benq board. That rev number at the end makes all the difference as there are subtle difference between rev numbers.. The schematics and board layouts and component designated numbers are different. Does anyone know where I can get the correct schematic and board layouts? Thank you

I had a desktop form factor mini-server die on me a few weeks ago. Through my initial diagnostics, I was convinced it was the motherboard because when I shorted the Green wire on the ATX connecter, the multimeter gave me all the correct voltages on the various pins of the ATX connector and 5VSTB was also correct. To my surprise the replacement motherboard wouldn't turn on with the case power button either. I threw in another PSU and it turned on right away. This is an 80 Plus EVGA 430W PSU with PN:100-W1-0430. I pulled the cover off and don't see any immediately obvious blown caps or scorch... -
Good day,
In my hands I have a Thinkpad T14 gen 1 (20UD002BIX) showing sporadic BSOD issues caused by failing onboard soldered RAM. I suspect disabling the onboard RAM via a bios mod would do the trick.
The laptop has already the latest updates as well as latest bios 1.51 as of today.
I informed myself in an attempt to DIY my way to victory but it left me with more questions than answers. This is not a BIOS request, what I really need is somebody to verify that the following procedure is correct.
Step 1: grab a bios image:

I noticed that in schematics is used random triac simbol, where on gate side is T1 or T2. I know it pass current in both direction, so generaly it is not important, but ask for consistency to learn correct. Why is developed this two way of marking if symbol is standarized?...04-27-2024, 06:26 PM

Hi!
Happy to be part of this forum for my first post!
Short story:
I believe my dad's UX51VZ has an incorrect bios (v207) for a UX51VZH flashed onto it. I'm not quite sure what the differences are between UX51VZ, UX51VZA, and UX51VZH. The serial number of this machine is D5N0CY845932229 and comes up as a "UX51VZ-DB103P" when checked on this ASUS website. All of the bioses can be found at this ASUS website.
1) Do I have the correct bios or should it be the v205 for UX51VZ? Is there something I can check inside the machine to make sure?

2015 macbook pro which has no sound.
Noticed some corrosion by the Cirrus audio ic. Resister R6324 had corroded off the board, pad indicated in pic is gone.
So soldered another 100k resister to the pad closest to the ic and ran a jumper wire as per pic to l6201 for the 3v.
Is that correct or should i be jumpuring to somewhere else?...
