Does anybody know why a laptop would turn off for no reason?
It's not the battery, cos I have it plugged in all the time.

please help me.

Hiya OceanWave :)

Is there any particular time the laptop switches itself off? (like when your running certain programs)

Run antivirus and spyware scans, if it continues to switch itself off i would have to guess at an overheating problem :?

i left mine switched off for about a year switched it on after charging and it kept switching off even though i had it plugged in
i left mine charging for 24 hours and that sorted it
i think it still takes power from the battery even if its plugged in
Hope that helps

Overheating. It may need a good blow off. i.e. dust on the inards syndrome. This should do the trick. I have the same problem, but only when my power cable is plugged in.

To be fair, it should be charging whilst plugged in - it'll be an overheating problem, I reckon.

:)

could it be power saving? set to hibernate after 20 minutes (or something) of inactivity?

power saving is shutting down your screen or your hard drive, check your settings

Start
Settings
Control Panel
Power Options

This is common with laptops that are plugged in all the time, it still draws power through the battery, even when plugged into the mains, it's happened to mine, my battery is dead now from leaving it plugged in all the time,

The battery has lost it's charge "Memory", resulting in a permanent flat battery,

Try removing the battery from the Laptop, if it stops shutting down then it's the battery causing it, it should still power the laptop even without the battery attached, this has worked on 2 laptop with the same issue

it happened to my think pad what you could try is use it without the lead if it doesnt do it then it will mean that the laptop is over heating the way to fix that is go into the bios settings and change the power settings to best for battery or powersave its something like that it cured mine for about three months but it might be better to get someone to check it out as mine died shortly after well pm me and let me know if that was any good for ya :thumbsup:

my laptop went in for that not so long ago and know its doing the same thing again and its really annoing me cause i have lots of work to do

My thinkpad had an issue like this,I flashed the bios witht he file from IBM and it sorted it,the updated bios allows the fan to kick in earlier thus keeping it cooler.

I disagree,I have owned many laptops and repaired alot as well,leaving it plugged in does not create a problem if the laptop is functioning correctly.

When the system is run on mains power,the charge circuit should be cut off once the battery is fully charged,if the system still draws power from the battery then the voltage supplied to the system would be too high and cause the unit to fail.

The battery fails because the will only accept a full charge so many times,over time the battery will lose the ability to become fully charged,after all they would not sell you a battery that lasts for ever would they.

One mistake people make is failing to discharge the battery before recharging it,although with modern batteries this is not required but its still good practice to do so.

I have along with others An IBM Thinkpad 600,quite an old machine but very reliable the battery still holds a good charge and will last for up to 4 hrs depending on type of use.
When on charge it takes only 3 hrs to restore battery to its full state and I follow all the methods I have stated above.

My laptop still works with battery inserted but it doesn't keep its charge anymore, the charge circuit will stop it charging when its full, and did when it was new,

But I had my laptop plugged in all the time at home, so when the battery lost a bit of charge it would start charging the battery again till it was full then stop again, it's this constant charging, not charging that kills the battery,

Plus the only way to discharge a battery is disable the windows auto shutdown when battery is low, and let windows run till battery runs out (not wise), or leave it running on the bios screen till dead, not practical,

Personally I would like to be able to stop the laptop charging the battery once it's full, then only charge it when it's empty or when I tell it to

Not everyone has one handy, let alone know you can get them, plus it wouldn't do my battery much good as it doesn't hold any charge anymore, would make a good paper weight tho
