Hey people, I was using my laptop, about to log in, when BANG. The screen went scrambled. I turned it off by holding down the power button and then rebooted it. It then got to the log in screen (in normal windows mode) and I went to log in but the laptop just shut down. I tried to turn it back on, but it would not turn on?!

I did some searching on the net, and people have said, take the battery out, disconnect the power and hold down the power button for 45 seconds. I did that, and hey presto! The laptop is back on! Supposedly it's to do with the CMOS battery? Can anyone explain that to me??

Perhaps if the clock battery is dead to the point where it cannot be recharged, or if it is a dead non-rechargable battery, the laptop might not boot up.

Laptops don't seem to like dead clock batteries. Probably best to just replace it. I don't know what type your perticular laptop will use (a service manual should tell you if you don't know), but they are usually just those small, thin, circular types.

Strange. I've never had a PC (laptop or desktop) not bootable due to the CMOS battery. Which battery did you take out to make it boot? The CMOS clock battery, or the laptops main battery? I have seen such behaviour when a laptop's main battery dies.

I took out the main laptop battery

So the main battery is to blaim, which is a common fault on all laptops. An old trick that I don't know if it works any more with modern laptop batteries was to put the battery in the freezer for a couple of hours. Seal it into a plastic bag and then stick it in the deep freeze.

I often used to work and get dead batteries working again. Something to do with correcting the chemical imbalance within the battery and returning it to normal. Worth a try if the battery is dead anyway.

I did read about that harrison a few years ago and tried it with a couple of laptop batteries. Can't really remember whether it worked or not, but I think it was for NiMH batteries only and that it would either not work or damage lithium batteries. I will have to check that out.

Im not sure its dead, I havent even had this laptop for a year??

I have a dead battery for one of my laptops, and I got another one, which unfortunately isn't working 100%. Ok, it's always better than the old one, but still, it only loads until 80% and decreases very fast.

I put the old one in the freezer yesterday to do a test have to remind me to take it out though.

That means nothing. Batteries can die at any point in their life. If it is less than a year old it is still covered under warranty so you can get a free replacement.

Just don't put in the microwave to defrost it...
