Every start, appears a bios screen.
Asus rog G75VX, I resolved a power issue: replaced a mosfet near the power pin, drived by the ACDRV signal from
TI BQ24735.
During a motherboard test phase, it appears the bios screen in a few seconds.
After reassembly the laptop:
- first start, after a lot of time (20 sec), appears bios screen but boot override with linux pen don't work.
- second start, after a lot of time...., bios screen, no device detected.
Using this setting, the laptop starts with the usb pen:
disable Secure Boot, Save and reboot, Enable CSM , after restart it boots with linux pen, BUT.
what is the cause of this delay ? I have noticed this is a common issue in Asus laptops and in some HP for example after the use
of a bios dump.
It could be a problem on ec, or ? (last week I have solved a similar issue on an asus, the culprit was a resistence on RTC RESET signal, but this is not the same situation)
I have a post card, but on asus notebook works only with jdebug port ; there is another procedure to see all bios post code ?
