Yes, I understood. that it will come to this, but this is the last stage and I really wanted to check out the “softer” options.
Unfortunately, I don’t have an infrared station for personal use, I’ll look for opportunities.
Thanks again for your help.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

[FONT=Calibri]What possible solutions might there be?
It is very confusing that identical boards have the same fault (symptoms).
Thank you.[/FONT]

I turned off DB2/DB3/DB4 sequentially, then turned it off in different combinations, also turning off all diodes.
Unfortunately, I did not get a positive result. The board does not start, shuts down after 4-5 seconds.
Signals via “PWR Sequence” remained the same, starting from PM_SLP_S5#, ESPI_RST# are missing.

Acer Aspire 5 a515-52g, EH5AW LA-G521P Rev.1a does not start.
Hi goodday to all.
I really ask for help.
There are two motherboards (absolutely identical) Acer Aspire 5 a515-52g, EH5AW LA-G521P.
Both boards have exactly the same fault symptoms. It turns on, the power indicator lights up for 5 seconds, turns off (the fan does not spin).
Both boards are flashed with Bios Main and Bios EC from the “Bios Acer A515 LA-G521P FULL TEST” topic. XM25QH128AHIG replaced by W25Q128JVSIQ (also NOR-FLASH, XM was not detected by the programmer). On one of the boards, KB9022 was changed, followed by firmware. The fault persists on both boards....

Hello.
Electronic engineer. I worked in service centers for 15 years, mainly repairing laptops. Now I have switched to working in the production of electronic equipment (medical), but I continue to repair laptops in my personal time.
I accidentally came across the forum and saw a lot of useful information.
Thank you, I really liked the forum. Deadlock situations often arise, and help from other participants is often needed.
