Technical Support Asus GL702vsk not turning on.

[Mamdouh]

Hi, the MB has 3.3v on the 64bit BIOS (but not the other BIOS). 5V, 1.2v and 16v(batt).
the power btn. pulls down the line on the MB connector when pressed.
the driver chip for the battery charging circuit is the only chip getting worm when plugged in.

Hello
Check carefully that there is no moisture or burn anywhere on the board.

In diode mode, test the motherboard model that does not have a connection on the motherboard.

Reprogram the BIOS.

If there is no connection and 3 and 5 volts are available, usually BIOS - SIO - PCH - Hall sensor - switch button and crystal are effective in turning on.

Hello, Ser HP 640 g1 When I put the battery in and turn it on, it comes on, but the screen doesn't turn on, It works directly with the charger, what could be wrong?

Thanks Ahmad. The Hall switch does give 3v and gives 0v when a magnet next to it. MB is very clean. it stopped working after it was sleep. should I have the 1.2v for the DDR3 active with the 3.3, 5v ? I just have the board view but not the schematics.

In the steps of not using the method, in the first step or standby, we only have standby voltages, such as 3.3 V standby and 5 V standby.
If there is DDR4 RAM, the voltage should be 1.2V, and for DDR3 RAM, the voltage should be 1.35 or 1.5V.

1.2V RAM is in the next stage when the system is switched (stage S4) and before the voltages of the switch stage are produced, the power supply voltage of RAM or 1.2V is produced.

Usually MBs takes 0.02A when idle but this MB starts with 0.02 then 0.05A and the battery charging chip gets worm.
Although the MB is very clean, I cleaned it with ultrasonic and it worked. Thanks

The Asus stopped working after I assembled it.
I found out that if I keep the power btn. pressed and plug in the AC adapter then release and press the power btn., it will work
I have seen this behavior before, where the laptops takes 0.05A and one or 2 chips get worm and no POST. any ideas? could it be BIOS communication? Right now it is on and updating Windows with no errors.
