Having problems with your Acer Aspire 5500 5570-2609 Laptop ?

Laptop screen flashes... i.e.... goes bright then dim

\015 I have a Gateway M280E Laptop. It works fine, but recently, when I have it plugged in (AC) the screen flashes bright then dim. When it is running on battery power, it's just dim, which I know is the norm. But it's not normal to be doing this on regular power. It's driving me 'crzy', because I can still 'surf the net', do email, do word processing... just with a flashing screen... HELP !!!\015

Answers :

Check your power supply. Maybe its wire is broken then intermitently making contact every now and then. Its my first suspect. Its like disconnecting and reattaching its power supply only in much faster way. Or test it with a good similar power supply if this will be the same.

Hope this one helps already.
