BIOS Aspire A514-54G FH5AT LA-K092P.

[huzo]

Can someone repair mine? I have 0.17A ,after power on 0.9A and the again 0.17A, other dumps give me fan spin and 1A draw 4 times sequence then stop at 0.17A,and the powers up,draws 1A ,but no picture

SN is NXA1JEX0052021F9913400 SNID: 20212942534 The board is : FH5AT LA-K092P Rev. 2.0 2021-10-18

The bios is corrupt, make another backup. The serial number is for an A515-56G ,the bios type for that is FH4AT . Check the motherboard model number again , is it FH5AT or FH4AT

This is the board,and it is 56G..unless someone already flashed the wrong dump before...

Ispravljena verzija:

Too late, I already flashed the chip, and it seems the chip was faulty because I couldn't erase it at first. Then it took only 10 seconds to erase, which seemed too short, so I tried erasing it again. After that, it locked up and I couldn't stop the program. I resoldered it to rule out any loose connections, but the result was the same. I also tried a different programmer with the same outcome. Then I took another chip and erased/flashed it without any problems. Unfortunately, I don't have a better backup copy.

ok so just try some of the bios in the thread https://www.badcaps.net/forum/troubl...22#post1749922

Make another backup and compare it to the bios you flashed, see if it looks corrupt. Check the bios with MEAnalyzer as well, it should have initialised the ME firmware. Try another bios chip , flash the EC , if that doesn`t make any difference then it will have some other problem.

I can't make another backup because the chip is bad...i tried like all dumps from the forum here...

I know, i want you to backup the current bios that you flashed to the chip and compare it with the file you flashed see if it looks corrupt. Check the current bios backup with MEAnalyzer as well, it should have initialised the ME firmware , if it`s still Configured then the bios chip isn`t being read/written to

The issue with the original chip was that it was faulty...with it the laptop drew only 0.083A at power on and went back to 0.17A, then i tried to read it and got what i got,and then tried erasing it and it was giving me trouble,wouldn't erase ,and then next time it said erased after just 10 seconds, then third time it locked the neoprogrammer,it was recognized,and i did read from it and made a backup,but it was something wrong with the chip obviously since the dump is corrupted and it wouldn't erase...I got heaps of donor boards and i took the other 128Mbit chip from some donor board and it erased succesfully and programmed and now i have everything going ,but no picture, the board starts and draws around 2A now and it resets a few times (4 or 5) and the sixth time it stays off,then i press the power button,fan spins ,proc is getting warm,all voltages present,but shuts down to 0.17A and then starts at 2A again ,probably charging...So i think it's either the bios or ddead GPU,but not likely the GPU,

Ok will try that dump from a banned guy ...

Why are chip types important?Aren't they all the same?

[SMDFlea]

This is the board,and it is 56G..unless someone already flashed the wrong dump before...

The motherboard is FH5AT . Someone has replaced the base cover from a different laptop or the FH4AT motherboard has been swapped with the FH5AT

[huzo]

Yeah could be,not gonna argue with that...

It matters on Intel platforms, MXIC branded BIOS chip won't work in this laptop, only the specific ones in the list (Winbond, Gigadevice, XMC, EON)

The other dump from post 3 on the thread I linked looks like it's from a working laptop and has Initialized ME region (not clean), if it works it may take long time to boot and won't detect SSD, you need to clean ME region on that one first

It's the same board and BIOS for 14" and 15" models it seems
Checked the BIOS for the A515-55 (not G) and the BIOS is also the same (labeled FH4AT in BVDT), even if the board is labeled FH5AT... (The schematics are labeled FH7AT/FH5AT/FH4AT LA-K092P)
