Laptop originally worked but was bios locked. After unlocking, won't post but power rails are all present CPU gets lightly warm and fans spin normally for as long as I leave it on. Already pulled a bios from a donor board (same board model, 3662) no change it won't post. I have tried NVRAM reset, it doesn't respond. KG keyboard, SMC reset works. I checked all the SPI termination resistors, no problems, as I said laptop was working, no physical damage.

Hello... Where do I start. I have 2 questions/scenarios that might bring this laptop back to life, so here it goes!
I have this laptop (Asus UX52VS) where I was flashing the BIOS to it and it froze during the process. I didn't have a reliable BIOS chip programmer at the time (It was a CH341A USB Programmer from Amazon where it took hours just to get the clamp on the chip and then every time I read, it gave me different results/corruption, and never would pass the verify test as no 2 reads were the same data), so I brought it to a shop. They had it for almost 2 months, but during... -
Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Hello, sorry for the long post, I just wanted to include any details that might help.
A bit of backstory - I currently have 5 of these MiniPCs - I got them for very cheap from Ebay. All of these PCs are BIOS administrator password locked without their drives.
I also got a G3 large tower, that I could reset the password of fine just using a header and a button on the motherboard.
So I thought that I could do the same with the G4 MiniPCs, oh how wrong I was.
First of all, I stumbled upon a tutorial, that apparently showed a BIOS password reset procedure - where I basically... -
Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
