auto shutdown laptop....

Hi, Even I had similar problems earlier with my old laptop. Then i felt it was due to laptop getting too heated due to no air circulation between the laptop and the bed. I later tried a laptop pad with fan. It was good and my laptop did not get too much heated after using this. But still it used to shut down at times but the frequency was less. If nothing works, call service center.. Good luck.. Regards

Hi asliah, Robin has the most logical explanation for your auto shutdown problem. The phenomenon is termed as "automatic thermal shutdown," for us simple computer geeks, we just say "thermal." This is a built in feature for most CPU chips to automatically shut down the power whenever core temperature exceeds certain limits, mostly above 60 degrees Celsius, to prevent permanent damage to the micro circuits in it. Tolerances in matters of nano-inches can easily be melted by such temperatures in CPU chips. When you place your laptop on the bed, it accumulates heat from the soft material on the underside due to lack of ventilation. Thus the auto shutdown: the computer is just trying to save his sanity for the excessive heat, so to speak. On a harder surface, such as a tabletop, air can pass through in between the small space of the laptop chassis and the table surface facilitating ventilation and cooling. The CPU chip may have saved itself but the one to bear the brunt to this unscheduled shutdown is the hard disk drive. Too much of it and the HDD may no longer start up if the "flying" stylus crashes on the disk surface scratching it resulting to data loss. Be careful to check the ventilation between the underchassis of the laptop and material it is resting on to prevent ATS. Some recommend packing some ice while in bed but it may cause short circuits if the ice eventually melts. Just enough space to let cool air to flow is enough, two books on either side as props may do. I hope this long winded narrative is helpful to you.

You might check the battery, or other function. You said the laptop was ok while you have it on the table. But while you were using it on your bed, it automatically shut off? I might not have slight idea why that is happen, and it really sounds weird. You might check the power category on the control panel, try to adjust it to longer than 1 hour or more.
