LE: Thank you @andrew25 It was my mistake. I was using a brand new chip instead of the laptop original chip. HP bios is paired to the MOBO. CH341A Does not support CHIP ID chgange to match the original chip so you need to always use original chip from the laptop. Thank you very much. I hope this will help others too! Andrew's BIOS is good!!!

try this one and report

Thank you for the response! With this one I get 5 blinks.
Is there a chance that my programmer is to blame even if I can Wipe/Confirm Blank/Write/Verify?

Hello. I have a problem with a HP 840 G1 laptop. My bios is corrupted (my original backup gives 2 blinks) I tried the files from @ridamouh159 and they give 5 blinks (mobo failure)
My laptop has only Intel graphics. I am thinking that the 5 blinks might come from the fact that I have a different mobo. My mobo is SPS: 730808-001 and I know for a fact that the laptop was good before the original BIOS got corrupted (bad read from chip). I have spare chips and I tried flashing a new chip with no success. My programmer I am using is CH341A.
Can somebody please help me with the proper BIOS dumps for my laptop?

Re: Bios needed for HP Elitebook 840 G1 (6050A2559101-MB-A03)

Thanks, but it's not the right one. There is one Winbond W25Q128 chip and one Winbond W25W16 chip so the bioses are 16MB + 2MB. I found some bioses on ******* forum and flashed them but the result is the same.

When the power adapter is inserted into the motherboard, all the lights for power on are immediately lit up. There are 3.3V and 5V standby. There is also voltage on coils for the battery charge (2 battery terminals) and one coil has about 1V. No other coil on the board has voltage. No voltage for CPU and no voltage for GPU. When I long press the power button laptop won't turn off.

Is it maybe the problem with KBC? I will upload high res photo of the board to mediafire shortly...
