Hello I have a 3 year old Toshiba Encore WT8-102 which had been working GREAT. After leaving it plugged to some PowerBank it never worked again Says 'no bootable device' and the biggest problem, the HDD is not recognized in the bios page. Any way to know what is the real problem? The bios settings are very limited. I have some experience dealing with PCs but i have no clue what to do / how to procceed. If the board is fried, shouldnt it be acting weird with other stuff instead of simply not recognizing the HDD? thanks Sample of a similar tablet bios. In my case, on the HDD/SSD it appears blank.
