Re: RT809H ISP programming for laptop bios.
Hi
Desoldering bios chip, in my opinion, is the best option. You connect only "this one" and You read/write software directly from/to this one.
RT809H is very good and useful for programming not only KBC and bios chips (ChipProg-481 seems too), but for effective work - desolder "it" :-))
CH341A programmer offers "on-line" programming bios chips too, but sometimes what You
see is not what You want when connected to the mainboard.
Good luckComment

Greetings badcaps community,
I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.
Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.
I have a Elitebook 820 G1 and a Elitebook 840 G2 here.
These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

My pc updated bios through Windows Update and I was greeted with BLACK SCREEN WITH CPU FAN MAX SPEED. I don't think there is even a screen signal, because it triggers my monitor for a couple seconds and then the monitor turns off. I tried the other outputs as well.- I tried clearing bios, resetting bios, removed the CMOS battery, removed m.2 ssd, wifi, and ram. Still black screen with CPU fan blasting.
- I tried using the Lenovo BIOS CD and BIOS USB, but neither worked. At least I couldn't get anything to work.
- I could only locate two chips that look like bios chips. Could someone verify this

Hi,
I have OriginPC EON 15SL, however, my laptop starts and shutsdown after 1-2 second. Keyboard leds are coming on then fans spinning then it shutsdown and not turning back on unless I plug out the power cable and plug it in. I had issues with bricked BIOS then I flashed BIOS I got from the vendor to the SPI chip and still it didn’t worked because my EC firmware was newer than the BIOS I have flashed. So I wanted to try flashing the EC chip with the correct firmware that matches with the BIOS also from the vendor and it worked everything was well, and then stupid me wanted to unlock some... -
Hello. I am asking you for a hint on how to solve the problem with my touchbook Panasonic CF53-2 standart model. After setting up the BIOS, the laptop displays the wrong image until Windows loads. (More precisely, it displays, but distorted, instead of the Panasonic image immediately after turning it on, it displays what is in photo #1 in the attached file) Then the image appears when Windows starts loading and then there are no problems with the screen until the reboot. If you enter the BIOS, just a black screen. If you connect an external screen, the image on it is the same as on the built-in... -
