My daughter’s laptop froze during a game, so she turned it off but it never came back on. The profile button and predator logo blink once, but that’s it. So after trying everything I could think of, I am now trying to flash the bios with a CH341A programmer. I extracted half of the bios file (upper 16 MB) from Acer’s bios exe. I plan to merge it with the other half, but when I try to read from my bios chip all I get are 32 MBs of FFs or 00s. Would anyone have the other half of the BIOS image?
Motherboard: DA0ZGPMBCD0 REV: D
BIOS Chip: GigaDevice PJ2314 25B256EYIG
If you cant read how do you expect to write it back humm???
If i may, can i ask what more clues have lead you to take the decision of manual re-programing the bios of the system?
Have you drained the system’s energy and tried to reset CMOS/NVRam? Re-seated SO-DIMM etc…
This device is a “VOLCANO” heater… with a 4090…absurd on a “plastic” chassi…ups seems this one is CNC aluminium body.
1.31 GHz @ 3.53 GHz @ 81°C @ 157W
1.55 GHz @ 3.48 GHz @ 90°C @ 157W
2.55 GHz @ 3.12 GHz @ 96°C @ 140W
How old is the system? Is it thermal maintained?
Of course! I don’t have a lot of confidence in my ability to flash a bios, so I saved it as a last resort. Prior to this I tried draining the battery & tried different wall outlets. Then I reseated the battery and reset & shorted the rtc pins. Then I replaced the battery with a brand new one and tried a brand new adapter. And finally removed the ram and tried booting with one at a time in case one had failed.
As for thermal protection, the laptop sits on a cooling pad with fans.
It’s just out of warranty, only 14 months old. The only other time it was opened was by Acer. (It arrived with a dead battery so I sent it back to them to fix so as not to void the warranty.)
As for the mini-programmers, I started with two older ones that worked a couple years ago, and eventually ordered a new one, but I get the same result - all FFs. Hopefully I didn’t fry my 3.3v chip with 5v from the programmer.
If you have any other questions or suggestions just let me know!
Just saw your first question - how will I write to it if I can’t read it. Good question.
I’m hoping it’s an error on my part that I’ll figure out. Or do you think it’s fried?
Well that’s not a valid dump and in this way you have no valid backup file… again if the reading of the IC is not valid then it’s not going to be a valid programming.
Once the IC is erased or bad programming, without backups the user loses the system motherboard original data, like Win key, SN, PN, MAC etc…
Some ICs must be desoldered from the PCB to be programmed, some systems need CMOS battery OFF/ON and /or PSU standby ON/OFF…
Only a user with same system, that had done the same can be your helper in this matter…
The 5v “Bug” is almost gone from recent CH341A programmers… usally a bad reading is due to bad contact/short…assuming this is a SOP8 and not WSON8.
The GD25B256E(YIG) is indeed a 3.3v IC
Okay, thank you! I will keep trying. I do have the board completely disconnected from everything (including battery and RTC). I will go through the guides you linked and see what I might be missing. Hopefully I don’t have to desolder it, but i will if I have to. Thanks again!
