Windows 7: Laptop crashes with black screen when connected to AC power

Laptop crashes with black screen when connected to AC power

Hello all,
I am using a dell studio xps 1645 with ati mobility radeon HD5730 inbuilt.

Problem i have been facing past few weeks is that my laptop screen is going black and is crashing a few minutes after booting up when i connect to ac power.

I did a few diagnostic tests. It is working perfectly in safe mode. It is working perfectly when i disable my graphic adapter and boot in normal mode. The tricky part is that it works perfectly with graphic card enabled when im using with battery. As soon as i connect AC power it crashes with black screen in a few minutes/seconds. I also uninstalled and reinstalled the graphic drivers and BIOS is also up to date

I recently updated my graphic card drivers but still it worked well for a few days. I could play games with no problem at all.
I used to have a heating problem aswell. The screen would lag and audio would distort. I have cleaned my heat sink now but cannot test it out as my laptop crashes. Also my battery is pretty old now and gives only 30 min backup.

Any help would be much appreciated

Can you try another AC adapter there? Does it behave the same?

Its quite hard to come by where i currently stay but i shall try. But how can the adapter cause this? Because the battery is charging when laptop is on and off too..

An AC Adapter not only charges a laptop but also works as an external power supply.

So it appears that the adapter is charging the laptop, but not supplying adequate power to the laptop to tun properly. In that case the issue that you are facing is most possible.

But we cannot test the AC adapter in hand. So a replacement adapter will tell us about the performance of the current one.
