Your Laptop Overheats

Due to the strong electrical resistance of your laptop  components, your laptop can heat up to 170 degrees. The shutdown is necessary to protect the components from melt down. < To fix the the overheating problem, stand the back of the laptop up on a laptop stand and allow the air to flow under the laptop and around the batter. It should do enough to cool the laptop down. If you don't have a laptop stand, I suggest you purchase an adjustable  laptop stand.  to keep your laptop cool.


Automatically Shut Down
your laptop shuts down because you have configured it to automatically shut down  shut down in your default settings to conserve battery energy. This happens after several hours of inactivity. To avoid this inconvenience, check your power settings in control panel under "Hardware and Sound" and  remove this setting.

So there you have it.  follow these suggestions and you can prevent the scenario where your laptop shuts down without warning.

No Operating System Found

So far your Fujitsu laptop is  playing great. It's functioning at the right speed and you're enjoying it to the max. So far so good. Until one fine day you turn the laptop on  only to see this scary message on your screen "NO OPERATING SYSTEM FOUND!"  You're like! "I've only been using this laptop for three years. This cant be happening." So you check your bios, and much to your horror, there is no hard disk.(BP starts rising). Not only is there no hard disk, but you can't even turn the hard drive button on. Even worse, your IDE legacy says 'Disabled. You start wondering "Is my hard drive faulty?"

Let's try a few possibilities.  Assuming the bios in your laptop doesn't recognize the hard drive, either the hard drive has gone kaput or there are some loose screws on the hard disk somewhere. Also this situation happens when   you accidentally knock the laptop to the ground. When that happens, the hard disk suffers considerable trauma , causing it to go kaput.

Another  scenario that could cause the hard disk to go kaput is leaving it on overnight on hibernation. Hibernation seems cool for a while. But at some point, the  laptop being all night 24/7 is bound to take its toll on  the hard disk causing it  to give in.

Now what to do in a situation like this? you could try a few things.  First, make sure the drive is properly connected. Then take the hard disk out and check the pins for damage and slide the hard disk back in...carefully of course. If the hard disk is not recognized,  you may need to fit the the disk in another laptop  by way of an external adapter to check whether the laptop works. if it doesn't work, then your hard disk has issues. You  will have to take it the technician to have it looked at. .

Another suggestion would be to to borrow a friend's laptop and go online to  download the "HDD diagnostic utility" from the website of the manufacturer of your hard disk. Then copy the program on your empty CD, and  the CD in the CD-ROM of your laptop. Then test your laptop hard disk for errors. Hope it works.
