Laptop problems i tried to fix a laptop that shuts down prematurely while the user is in the middle of working.the power battery may be on,also the hard disk light is also on.when i try press any key it doesnt respond.so we end up removing the battery or pulling out the power supply

Ebay battery? made in china? that happen a lot.. most laptop battery are designed with the proper voltages, Watts so on and so forth.. don't be fooled on a cheap battery sold on ebay it may works but only few times, what it does is restricting the power to your laptop and obtain time laptop can't handle the power... buy OEM replacement battery..

When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

try to do a hard reset and check if it works..
shut down the pc, take out the charger, take out the battery, press and hold down the power button for 20-30 secs. then put back everything in their place and turn it on.. see if it works.

Hi there.
Remove the battery and try to format the HDD on AC power only, if it still shuts down get a tin of compressed air and give short blasts through the air vents and the CPU fan which will be located on the underside of the laptop, this will remove any dust or foreign objects from the machine which could be causing it to shut down prematurely.

Good luck and thanks for using FixYa!!

if power is the problem then it shud run ok on battery if thats the case otherwise

i will insist that u change the RAM chips or atleast try one at a time if u have 2 chips of RAM may be one is giving u problem or if u have other notebook available try swapping the RAM from there and see if it works pls let me know with the results if it doesnt give any propmt and shut down suddenly it sure a hardware malfunction/conflict scenario

are ur drivers update have u recently updated any drivers after that this problem started , why dont u try restoring to an earlier date from system restore , what about safe mode try to go in safe mode when system boots up press f8 or f11 and see if it does the same in safe mode as well

u can get more help and pls rate me if fixed ur problem

I don`t know.

Hi,
by pressing the power button in, the computer has gone into standby or hibernate mode.
Heres what you Do:- press and hold the power button for between 10 to 20 seconds.
that should bring it out of hibernation.
if that does,nt work. remove the main battery.
when you,ve resolved the problem, run a disk-scan via your windows operating system.

is it hot when your laptop shut off ?
if it is, try to clean you cpu fan and heatsink

With the battery removed any interruption of the AC power will cause the laptop to cut off. The power adaptor may be faulty or intermittent or more likely the socket on the laptop motherboard may have a dry jointed connection. These problems would not be apparent with a charged battery fitted.
Otherwise [especially with P4 type processors] overheating could cause cutting out - clean any fans and make sure vents for air intake are not blocked [by bedding etc].

Its late, so just to make sure I'm not brain-dead basically your laptop runs fine as long as its powered by the AC adaptor but dies fairly quickly while running via battery. This is very typical of a battery that will no longer hold a charge, not normally a user repairable item. It could also be that the charging electronics (in the laptop) isn't charging the battery, again not a typical user repair job. About your only option short of taking it to the repair shop is buying or borrowing a battery as a test.
