Re: HP 450 G2 & 470 G2 Bios dump CLEAN ME ( 4th & 5th gen Intel)


Hi Alfred, thanks for your replay. Bios is working but it show advice at startup. In any way I skipped it and boot in windows, so I edited DMI using WNDMIFIT tool (I don't know because Feature Byte change when I close and reopen this tool). Also I can't edit UUID.
In any way pictures attached.
How can I remove this advice on start up?

Hi, I have this original BIOS dump not working for HP ProBook 450 G2 no graphic version as blink continuosly white led of DC jack.
I tried to use a cleared working dump found on net, so inserted by HEX editor DMI information and it's work fine but hard drive is not found as into boot order there is mSATA only into UEFI section so i think this is the issue, also start up is delay like 15 sec.
Anyone can clear my bios dump keeping DMI info please?

Re: Acer nitro 5 an517-52-55aw

Hi hoaca388 and thanks for files!
First I flashed BIOS with TL866A, as this minipro not detect XMC chip model so I selected W25Q128FV chip model disabling Check ID but same issue.
Then I flashed EC, when MB start keyboard light colour has changed, now is white, before flashing EC was red and absorption increased up to 1.56 Ah, when close display absorption decrease to 1.25 Ah but same issue, no video
Maybe TL866A is not good?
Or something is wrong on MB?
