1- Scanning computer to eliminate malwares, spywares and the viruses from your laptop.
2- Repairing and cleaning Windows registry.
These two tips are found to be very helpful to fix the laptop shutdown problem. Almost all the computer users surf internet which could result in viruses attacking your system. Some of these infections are really pesky and cause the machines to shutdown randomly.
The registry errors, however, are the internal errors and can become a cause of system crashes and freezes. The registry keys shall be in good health to keep a system perfect.
When I noticed my pc keeps shutting down everytime, I tested the Intel Software Partner, RegInOut to fix the random shutdown problem with my laptop.
You could have an overheating problem, The CPU shuts down when it overheats and the laptop won't bootup until the CPU has cooled down.
The overheating problems are caused by a faulty fan or the heatsink/fan assembly is clogged with dust which prevents proper cooling.
Check the fan to see it it spins freely, if not (it has a bearing problem) then replace the fan. Also remove and vacuum the dust off the fan and heatsink.
The fan may be cluttered with dust. Clean it. Then turn the unit on and watch to see if the fan does indeeed work. If it does not, shut the unit down till you get a replacement fan. The fact that the unit shuts down is a saftey feature to keep your Proceesor from being damaged.
If cleaning it works, your processor should be ok.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it. Thanks, Joe
If the battery is removed, it should still start up with the charger connected. A lot of laptops develope problems with the jack where the power supply plugs in, from constantly plugging & unplugging the charger. The jack in the back of the computer is probably bad.

Try running a good malware program like AdAware. Often these spyware programs can driver your processor to 100%, causing it to heat up too much and shutting things down. Once you have the anit-spyware loaded, bring your system up in safe mode. This will allow the spyware to search the hidden partitions on your fd, along with the rest of the disk. R-.
