Ok guys, in the end I flash the BIOS Chip and everything is ok now, I really don't understand why the BIOS corrupted though, maybe about efi/uefi - mbr/gpt missmatch installation. There is a way that I miss to try, that is [B]editing efi/uefi from cmd[/B].
again, thank you everyone, this problem solved.Ok guys, in the end I flash the BIOS Chip and everything is ok now, I really don't understand why the BIOS corrupted though, maybe about efi/uefi - mbr/gpt missmatch installation.

Operating system not found, cannot enter bios or boot to usb
Hello everyone, I had issues on my laptop acer 4752G
I'm using windows 10 until I decided to install windows 7 because of old hardware limitation, then I just found I cannot access my bios anymore. So far I already try these:
1. On system information its uefi not bios/legacy
2. Advanced restart but there's no uefi setting
3. Try to reinstall my pc using fdd but cannot enter boot selection
4. Press f2 f8 f10 only beep but straight into boot
5. Try reflash bios using fdd fn key+esc+power not success
6. Take the cmos battery off and...

Re: Bios and Schematic HP 840 g1 - 6050A2560201-MB-A03
Yes you can reprogram Main & EC with CH341A, I've done it few times.
But you have to take the Main chip out from board or it won't readable by the programmer, and for the EC you can reprogram it directly using adapter.
here's the picture

this may be important notes except you know different ways:
-use [B]default CH341A software[/B] for Winbond
-use [B]asprogrammer[/B]...

Re: Migrate from MICRON to WINBOND SOP8 SPI flash
Thank you for reply, and just as I thought I never know about this VSCC table. I want to stick with the same chip model but I can't find anywhere in my country, so I have to find alternative.
I may take your advice, it may be not the bios chip, it may be the ram or something else, I'm using diferent RAM brand with the same spec, only the timing slight different. What makes me to think it is the motherboard was the blinking count.
Thank you SMDFlea, I feel very reassured...

Migrate from MICRON to WINBOND SOP8 SPI flash
Hello guys, I need some advises.
I'm buying used Elitebook 840 G1 laptop with EC & Main BIOS chip in it. The EC is Winbond 25Q16BVSIG and the Main chip is Micron N25Q128A. My laptop randomly crashing with glitched screen and static sound, and then it won't turn on with 3x5 blinking capslock (which I know it's board failure).
Then I tried to reprogram these chips with different softwares. I'm using CH341A, default CH341A software for winbond and using asprogrammer for micron (since micron chip cannot be reprogrammed using default software). It's work and my laptop...

Re: Bios and Schematic HP 840 g1 - 6050A2560201-MB-A03
It's hard to request smc.bin from HP if you don't have first-laptop-payment-notes as evidence as the right owner, it's elitebook afterall. And they need you to capture Device Information Screen or something like that. I tried before and always rejected.
In the end I down to reprogram my Main+EC chip using CH341A with 2 different programing software. You can reprogram Winbond EC chip onboard without desoldering using SOIC8 clip adapter, and for Micron Main chip you have to take the chip off or it...

Re: Elitebook 820 BIOS update failed
Update!!! Hello guys !!! Finally I'm done repairing my Laptop!
After long thought in the end I'm using W25Q128FVSG chip because it's easier to reprogram without desoldering first.
At first I thought I can use bios file extracted from HP BIOS updater and it's a mistake (dumb me ), my laptop won't turn on. The LED keep blinking white and yellow nonstop (I guess the soldering wasn't good, but it was good).
So I made a new thread:

Need HP Elitebook 820 G4 BIOS file.
Hello everyone. I just failed to upgrade my laptop bios via HP software and now I down to reprogramming my chip. I want to buy this BIOS file from some website but I got no creditcard
I'm really grateful if you can share this file with me (and if there's fee needed, I'm willing to pay with IDR). thank you

Re: Elitebook 820 BIOS update failed
Thanks bro, this is very reassuring. from the paper JV series can operate at higher voltage + faster read speed The motherboard currently using 8-PIN WSON type, but it provide 8-PIN SOP too like in the picture, I wonder if that's meant to be able to use another chip type.
Thanks for the reply. Yes I can reprogram the chip using CH341A, and yes I intend to keep using the same chip, but if, if the chip's gone bad after desolderin, I wonder if I can use another chip type as an alternative (and 8-PIN...

Elitebook 820 BIOS update failed
hello everyone, I need help troubleshoot my laptop. So far I already tried:
[LIST][*]Unplug the adapter & battery, push power button 30sec.[*]Unplug adapter, battery, cmos/rtc battery, and push power button 30 sec[/LIST]
but still no progress
it's happen when I try to upgrade BIOS, it's said my laptop will restart several times and it's normal, so I wait for about 5 hours with adapter plugged and no completed sign at all just blank screen and caps lock/num lock light blinking (and keep restarting again and again).
I planning to change...
