Can someone provide a photo in the best possible resolution around the EC chip, EC controller and BIOS chip.
I need to compare whether there are any SMD components missing.
It is a HP EliteBook 840 G9 board, 6050A3417601-MB-01.
I unsoldered the BIOS and the EC chip, but since then I can't start NB.
After connecting the USB charger, the orange power LED flashes 5 times. it repeats 2 times in a row and nothing.
If I connect only the battery, the same thing happens as when connecting the charger.
If the battery is connected and I connect the charger, it charges normally.
The 3.3, 5V power supply works and the 1.8V turns on for a while, the smaller chip on the CPU starts to heat up, but after about 5 seconds the 1.8V turns off and nothing more.
I have no idea what could have happened, I've done it many times and nothing like this has ever happened to me.
Thank you in advance.
