3-The Pwm ic i dont know if it was blown but i replaced.
4 The TL 431 blown, (replaced)

Re: HP Elitebook x360 1030 G2

First of all thanks for your reply.
In attachment there's the dump removed from the 128Mb bios chip.
Do you want the dump from the other chip?
I must solder the wires then to motherboard to make the dump, but you can check if this dump is ok?

HP Elitebook x360 1030 G2
I there
I have a problem with the motherboard of this notebook.
When i connect the power supply the power supply LED blinks 7 times, i was researching for this problem and found that this is a BIOS related problem.
Then i flashed the Bios with a CH341 programmer and soldering tho the motherboard and still the same problem.
Does anyone had similar problem or possible solution?
note: I flashed the 128Mb bios, could the problem be on the other bios chip?

Re: HP EliteBook x360 1030 G2 dump urgent
I there
I have one HP EliteBook x360 1030 G2 that the screen does not have backlight. The pc boots normaly but when i changed the screen, because the old one cracked, the screen backlight stopped working.
I have the chance to buy a used motherboard with bios locked supposedly working properly, can i copy the dump of the Bios of the old working and program the locked Bios with that dump? Since it has 2 ic chips, which one should i copy?
Appreciate the help in this subject.
