Default Laptop keeps turning off.

Hello, I'm Bill.
I have been given a Toshiba L650 to fix for my sister. The problem is that it turns off just as it goes to the desktop, I took out the fan and the cooling pipes cleaned them all and then put it all back in with Arctic Silver 5.
The laptop started fine and I thought I had a win but about ten minutes later the stupid thing turned off again, it did this several times.
Has anyone had a similar problem as I am stumped, it may be that I have taken a two year break from computers and my brain just isn't working at the moment.
Any help will be appreciated.
Many thanks, regards Bill.

I worked on a HP throw away laptop that was doing the same thing. Turned out to be a bad cell in the battery.

Have you tried using the laptop without the battery to see if the same thing happens?

Also try booting up into safe mode and see if it turns off.

To get to safe mode , when booting up right after your computer logo dissapears, keep pressing the F8 key on the key board and it will bring up the start up menu...then choose safe mode.

Hello, thanks for all
your fast replies, I have tried going into the safe mode with the same results, I will now try it without the battery and let you know the results.
This is one of the reasons I stay away as much as possible from laptops, they're to small and costs can be more than the laptops are worth.
Many thanks, regards Bill.

Hi again, I tried it without power, without a battery and even put in the battery out of my wife's laptop which is a L660. It still shuts down after about 5-10 minutes, I did forget to add that it makes a click sound when it shuts down and you have to wait about 15 minutes before you can start it again.
Any other ideas what it could be?
Thanks to all, regards Bill.

This might help, Try taking one stick of ram out at a time and see if there is a change..

I know this one. If there is anything of value on that drive in the time it's running, copy it off. Drive is about to go.

Hi Bill, welcome aboard. Take that laptop and toss it out the window.

I've owned a lot of laptops and I had pretty good luck with them. I grew up with brands like Compaq, HP, and Gateway. I tend to stay away from Toshiba's though as I heard they can have lots of problems. Also all the HP lappy's i've had tend to run hot, and that's not even gaming on them.

EDIT:
But that's the only issue I had with my HP laptops, other than that...they run fine.

Yes that's one way but I might just accidently leave it on the driveway so the missus backs over it, it will work to as she managed to hop out of her auto car with it still in drive and the car went though the auto garage door, yep $2200:00 later and we could open it again.
I'll just have to keep plodding on, Cheers Bill.

LoL..Well good luck to you Bill, and don't be afraid to try a different laptop in the future. I have always used laptops and I had pretty good luck with them.

EDIT:
Out of all the laptops I've owned I only had one HHD go out on me.

Hi Mate, Your right about that, I've got another Toshiba that has a warning come up when they start it saying "the hard drive is going to fail" so I took the hard drive out and out it into my test bench to check it and is was going to fail, I managed to save the 1000's of photo's and then it failed. This is the first for me to. I've put a SSD into it and it runs perfectly now so that was an easy and quick fix.
I use laptops but I just don't like to work on them but family is family so you do what you have to do.
Thanks to everyone for your help, I think I might just replace the whole cooling system.
Cheers to you all, Regards Bill.

It's a good thing you got to save all those photo's before it failed. Well good luck to you my friend.

Hi Bill,

I know this is a bit late, but have you tried disconnecting the hard drive then attempting to boot up the PC? If the PC stays on (it'll just display an error message on screen as no Hard Drive will be in the machine), then try putting a different hard drive in the PC and see how long it stays on for.

As for the "click" sound. That's actually fairly normal when the power is immediately taken away and doesn't necessarily indicate hard drive failure. You can replicate this sound yourself by holding the power button on the laptop until it switches off (kills the power immediately).

EDIT: For some reason I skipped over your most recent update simply because it was written in a different font... glad to hear you fixed it!

Well in light of all that's gone on in this thread, I'd have to say it got wet. When lands and SMD components get wet they grow metal hairs that can lay over and cause shorts. That would explain why it's doing what it does regardless off what's hooked up to it. A stiff brush over the board might dislodge what ever hair is causing the short. But then you're going to need a powerful magnifying glass to see them to start with.
