HP 840 G1 not power on fixed https://bios-fix.com/index.php?threads/hp-840-g1-not-power-on.49771/#post-82135
Hello, I have a 840 G1 with motherboard 6050A2560201-MB-A03 and SPS 730803-001. I was trying to dump the main bios with an unstable soic test cable when the ch341a got shorted, and the laptop got in blinking mode (power led blinking in white and orange). Tried flashing main bios, EC without success. I don't know if it's just a matter of bios reflashing or something got burnt on the way. Thank you in advance.
try with neo programmer to read/write bios chip https://bios-fix.com/index.php?threads/ch341-software.49844/
I already use neo programmer, with the current EC chip the led blinks in orange and white alternatively. When I changed the EC chip I got the following behaviour. Thank you very much.
