Thanks, qayyum786. I made a rookie mistake in my haste to flash the BIOS. I forgot the battery was still when I was placing heat tapes on resistors and capacitors around the BIOS chip to prepare for desoldering the BIOS chip. I ended up shorting the BIOS chip (it burned). I replaced it with the same part number from a donor board and flashed your bin file but now there's no power. The laptop doesn't turn on anymore. I tried with battery only, power adapter only, and battery with power adapter with the same results, no power. I guess I might have damaged other components besides the BIOS chip...

Thanks, Hoaca388 and Shiyab for the files.
I tried Hoaca388's file and it worked. I have display.
However, I lost DMI info (S/N, Model #, UUID and Windows Key) as shown in the picture.
I tried using the Lenovo Uone tool to write the DMI info but I get an error "Locate protocol with LenovoEeprom, status [e]"
"Eeprom fail when reading or writing data."
Is there a way to fix the DMI tool error? I'd like to try that first if possible since I'd prefer not to desolder the BIOS chip again.

Thanks, Hoaca.
After flashing, when I turned it on the first time, screen turned on but after the ROG logo the screen froze displaying only statics lines.
I force shutdown and it's behaving as before; turns on but no display....

Thanks, Danito.
Flashed it but still no luck.
When I press the power button, the fan runs at full speed and nothing else happens. No lights on the keyboard
I guess this confirms it's not a corrupt BIOS issue.
I appreciate the time....

Thanks, Hoaca388.
I flashed the BIOS and it's still the same.
I guess it's not BIOS related.
I appreciate your time.
Cheers!

Please help with my BIOS.
Unsure what exactly I need but I am assuming a clean ME.
Any expert here please suggest or point me in the right direction as to what might fix my issue.
The laptop was working fine. I got a notification about a critical BIOS update to prevent a known charging issue.
I updated BIOS using Lenovo update utility after the laptop won't boot.
The power LED turns on for few seconds then off and repeats.
When the power adapter is plugged in I can hear a high-frequency sound similar to what's described in post #9 of this thread.

A million thanks Guyyum786.That worked.
For newbies like me, I found this how to video that was very helpful in using the HP BCU tool [URL="https://www.youtube.com/watch?v=aimAllxphic"]hp DMI tool || easy way to update serial no || manufacturing mode off (youtube.com)[/URL]
It does a walkthrough, original language is not English but provides texts in the video of the important steps so I was able to follow without understanding the language.
Also, I run into an issue on boot with a MPM error "Cirrus Discrete Amp Calibration Data" Missing or invalid....

Thanks!
It worked. The BIOS password is removed but I have the MPM countdown. I have updated the device information through "Set Machine Unique Data" in the BIOS but still have the MPM enabled.
I'll wait to see if it goes away after the countdown reaches 1.
I will update the thread once the countdown reaches 1 or whenever, the MPM goes away.
I appreciate the help.
Cheers!...

Thanks Gayyum786 for the quick response and the file. I followed the instructions but there was no option to reset BIOS. The first screen I saw was information stating "there was mismatch in the BIOS and it has been recovered" and the only option was to press OK.
After that the BIOS lock is still on.
Not sure if I did anything wrong.
Thanks again for the help....

Can someone please tell me what the part # of the BIOS chip is? I need to unlock my BIOS but when I opened the laptop, I see two Winbond 25W256JVEN chips (U367, U368) and I'm confused about which one is the correct chip to read/backup. Thanks in advance....

Re: Acer Nitro 5 AN515-54-58YY
Thanks
I flashed the BIOS then the EC files.
Not laptop doesn't turn on at all. Its charges when I plug in the power adapter.
When I press the power button, nothing happens. The power LED turns on for a few seconds and turns off again.
Not sure if it's just a coincidence or BIOS related.
I flashed back the original BIOS backup file and still the same. Laptop not powering on.
Any ideas or pointer on what could be the issue?
