power button the power is on but the screen remain blank(completely black). i already drained the battery but nothing happens. and when i plugged the charger , it has a short beep sound and also when i unplugged it has a short beep sound. im confused and dont what to do. i have so many important documents in it and im scared thinking if i can still retrieve it.
thanks for the response.
