What should I do if the power indicator (Green) lights but my computer screen stays
blank?
Follow these steps:
1 Press the power button for more than four seconds to check that the power indicator goes out. Then turn on your computer
again.
2 If your computer screen still stays blank, unplug the AC adapter, remove the battery, and leave the computer for about a
minute. Then plug in the AC adapter, install the battery, and turn on the computer again.
