What you do is get a new charger.that's what is what was wrong with mine
well i have a laptop so if you keep your battery on your laptop forever like since you got it will get use to your laptop and it wont do anything but if you keep it on for a little bit then take it off
Yes. extra monitor wont work If this is a laptop, power the laptop down, unplug it, remove the battery, press and hold down for up to 1 minute, plug it back in and power it back on without the battery attached. May take a few times.
Turn down the brightness settings
Check your battery
If the battery is good and the starter is good, then you must have a wire disconnected somewhere.
Turn you battery round the right way and it might.. :)
Turn your laptop over, theres a slide catch on nearly all laptops, slide it over and take out your battery, you can have a guess then at what size it is.
