My Studio 1535 (laptop with Vista) suddenly stopped showing any display a few days ago. I have tried disconnecting the power cord and the battery, and doing a shutdown by holding down the power key, but none of these methods have had any effect. I have had nothing but a blank screen, but when I attach an external monitor, everything is operating properly on the external monitor, so it doesn't seem to be a processor issue. The day this started, I went to boot up the computer and there was a lot of beeping going on, so I had to remove the batter and the power cord to make it stop.
I also have flashing volume control keys, and was wondering if that might be a clue to what is going on, and what needs to be corrected? The Mute key and the Volume Up key are flashing on and off at the same time. The Volume Down key is steadily on. I will say that prior to about two weeks ago, the Media shortcut keys had all stopped working for about a year. Suddenly they started working again, (and actually continue to work), but the monitor is just a black screen. Any idea if this could be a backlight issue, video chip issue or something else? I'd like to at least be able to salvage the laptop for my kids to use if the fix is not too expensive. Thanks!
(This all began after a recent iTunes update, but I'm not thinking that is related. Just throwing it out there.)
