Hi Everyone,

A friend brought me his laptop to have a look at. the display had been developing horizontal line across the screen and kept defaulting to the lowest resolution in the display settings. Ocassionally the screen would not come on at all although a restart it would usually come on. However all issues were becoming worse. We updated drivers etc. One suggetsion was to check that all the cables were properly seated. So last night, using dells online manuals, I did just that. Now it seems I have made the problem worse. It will not start up at all. When the power button is pressed, the power light and hard drive light come one briefly, along with one of the other lights by the wi-fi and bluetooth lights. After a few seconds they all go off. The battery light flashes every ten seconds or so when plugged in.

Does anyone have any suggestions?

thanks in advance.
