Windows 7: Laptop restarts 50% of the time when the power cord comes out

Laptop restarts 50% of the time when the power cord comes out

Hi there, I suppose this issue could be seen as a need for a tweak (but apologise if I am posting in the wrong forum).

I have had this issue for a while with my Dell Studio XPS 1645 laptop.

It is a guess, but i'd say 5/10 times the power cord comes out of the laptop (for whatever reason - moving it etc) then the laptop will simply black screen and instantly restart and boot up again without an error message or any information as to why.

This doesn't make any sense to me because every time I do have the battery pack inserted into the laptop and over 30% battery life (this is when ill plug the charger in).

If anyone has any ideas, please do post that would be super.

Thanks a lot, Nick

The power cord issue could just be a red herring.

How long have you had this computer? The reason I ask is that it's quite possible the CMOS battery wants changing.

The batteries normally have a life of three to five years depending whether it is a rechargeable battery or not.

You mention inserting the laptop's battery pack. Is there any particular reason why you remove it in the first place?

Hi there, thanks for the speedy reply.

I have had the laptop for just over a year and so I guess it cannot be that. Also, when I say I insert the battery pack into the laptop, this is done extremely rarely - maybe twice in its lifetime for no particular reason (sorry after reading through my post it does seem as if I remove the pack very often!).

As the CMOS battery is not very old, you might want to consider resetting the CMOS chip itself: How can I reset CMOS / BIOS settings?

Failing that, you may have a motherboard issue of some sort.
