Hi,
My Dell Precision 5510 stopped working: Black screen, fans spinning, power led turns on and after several seconds shuts itself off. CMOS / RTC battery was ~2.4V. gives the black screen and shuts down. Thumb drive with BIOS rcv file didn’t work. Display test using the power + D key works.
Next step is to check the BIOS. Ordered a CH341A which will arrive in 2 weeks but I have some questions on the process:
- Is there a guide specifically for Dell 16M + 4M BIOS configuration?
- I understand that the 16M and 4M chips need to be read and combined. How should they be combined? 16M then 4M? is there padding, alignment…?
- The BIOS Precision_5510_1.23.0.exe file needs to be unpacked. I ran a python unpack script and got a .hdr file. Now what?
- Which offsets need to be overwritten from the files that were read?
- What if the current BIOS is completely corrupt. Isn’t there a file that can be flashed as is?
Really appreciate the assistance!
