Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice... -

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered... -
Just had a customer bring in a HP 14s-fq1010nm to do some maintenance.
After updating the BIOS to the latest (F.35) I get black screen (no backlight turning on). However the backlight turns on if I connect an external display to HDMI, but when booting to Windows, both displays remain black.
After disconnecting internal LCD, and plugging in external display via HDMI, it works on external.
I tried downgrading it using official method - using an USB drive with older BIOS version, but it fails, saying that the BIOS files are corrupted. I used about 5 different older BIOS versions...
