What gives?
Well, not enough information to make a good guess.
But I’m going to go with:
- It’s overheating and going into protective shutdown.
- There’s a bad connection in the battery circuit or AC power circuit.
- It doesn’t like you anymore.
There are viruses that shutdown the system at random times.
But I just fixed a friend’s laptop computer that was doing this. The battery was defective, and not charging, so it shut down just after boot. So verify the battery is good, or run it on <AC only> to test, if you can.
Is it really turning itself off, or is it just hibernating? Does it have to go back through the bootup process after you turn it back on?
Some laptops are configured to go into hibernate after a period of inactivity, at a particular low battery %, or whenever the display is folded down and closed.
Mine does the same thing, it shuts down at random. When that happens, I turn it upside down and clean out the vent on the bottom to keep it from overheating. Then it works fine until the vent gets clogged again.
- I assumed it was the LT overheating.
I leave the battery and AC cord “in” while using it. -Thought this was the “Correct” way to do it… Use AC when you have it, but leave the battery in so it kicks in if the power goes out, so you can save and safely turn off the LT.
And yes, I do clean the fan vents… A LOT of lint collects there… but it does little good. (Laptop still turns off)
- Not Hibernation, the LT shows all Boot screens. -But do not get me started on Hibernation…thats a whole other kettle of fish.
3.Battery is great. Ran it off the battery to post the OP.
Folly, Ironically (and frustratingly) this is what happened with my previous Laptop… a 2001 Vaio… Im sure some peeps can realate. -However this one only started being a hassle later in that lts Life.
I have a Wal-Mart bought “Averatec” which I think is big in Dublin… To replace said above computer. It was 1000 and did more than double what the VAIO could do… which would have been 1600 (yes 1600) to fix.
When my IBM laptop got old there was something funky with the battery that would cause the system to shutdown. I finally removed the battery, because I never used it anyway, then it worked fine.
There’s a quite thorough laptop shutdown-tweaking page here.
IIRC, when my Windows 98 laptop sometimes failed to start up again, I found a power system logging app somewhere in the Windows directory.
It didn’t help me much, but it could help you if you look for it.
I had a problem like this on a Toshiba laptop. I took it in to get looked at after trying all the standard overheat/battery/bios fixes and it turned out to be a problem with the motherboard. Unfortunately, it’s so expensive to fix a motherboard issue on a laptop, it’s usually just as economical to buy a new one.
Is the laptop new enough that you are still under the one-year parts warranty that most manufacturers provide? Mine was over a year old so, I had no luck there, but the Toshiba service company said they would have replaced it for free if the issue had happened before the warranty expired.
I’ve seen many laptops that will overheat if they are not on a flat surface like a desk top (hmmm… if you can’t use it in your lap can you still call it a laptop?). What kind of surface are you using yours on?
We could call it a desktop! …oh wait.
Meeko, did you ever try it with the battery removed? AC only?
I don’t want to attempt to use power only.
Its on my desk.
It is still under warranty, but I wonder where my documentation is. :smack:
Why not?
