Unplug battery

Well mostly when the screen goes completly blank I grab my camera charger and give it a good 5 hr charge, that sorts it out mostly.

Hello,

The screen cannot display anything, not even the charging display because the flex of the screen of your phone is faulty.

All you need to do is to replace the flex on the screen of your phone in order for the screen to display.

Take care.

If you plug the charger into the computer without the battery and the laptop runs fine, then I would suggest to you that your battery is failing and will no longer accept the charge. On the other hand if the laptop will not stay running or acts strage and the screen dims and gets bright, then I would suggest to you that the charger's built in voltage regulator is failing and will damage the laptop if it continued to be used. A bad charger will also permenently destroy the battery condition.

1. Make usre you charge ur laptop for max 1-2 hours.That increase ur laptop life.
2. Take out the battary,Press and hold the power button for 1 min.Put the battary back and turn on.

Get it checked from your supplier it might be defective screen
