Just have killed my notebook by enabling CSM (compatibility support module) in BIOS settings. Screen is full of garbage, have no way to open bios and reset it. Any way to reset it’s bios settings to factory defaults or reflash it? Also BIOS image cannot be found in the internet. I’m very sad. Any support is appreciated
Update: solution was to completely discharge (not just disconnect!)) battery. Made using usb cables to charge and tablet overnight. BIOS had been reset after that
Open the back panel of laptop, disconnect the battery connector, leave it for 10-15 mins, then reconnect battery and power on. This should reset the BIOS settings to factory defaults.
