Several things it could be but im going to look at the obvious the battery and cord hook up
laptops when plugged into contstant 120 power the battery is supposed to go into stand by mode and shut battery off so power dont leak into battery
if you have low battery with it plugged into 120 the comp will still think the battery is powering the laptop if battery dead then comp shuts down lack of power

other thing is somehow you caught a virus that reboots comp from dos screen mode
the main thing i always ask is what was the last thing that happened before it did what its doing now
example= was there a power surge pop up screens ect.

    I have completely replaced power adapter and battery with no change. I feel this is something to do with a bad circuit board in the laptop. I here the power relay constantly cycling. And sometimes it does boot. Virus no, this is a pre-boot problem would love to know the most likely board and part number for immediate replacement.

Reset factory settings for toshiba S241-504


Back up all of you data to an external drive before you begin the process
If you make a mistake during the process, your laptop may not be able to turn on or load the
operating system, so copy valuable information to media where you can retrieve it, even if your laptop malfunctions.

Turn on your system and wait for it to finish loading Windows and start-up programs.
You can tell when the operating system has loaded, and start-up programs have been initiated, by the HDD (hard disk drive) light.
It should have came with discs. Put one in and reboot the laptop
Insert the system disk when the hard disk light stops blinking, signaling that the processor has finished accessing the hard disk, and that the system is idle. Shut down your laptop after you insert the disc.
You do not have to wait for the computer to access data from the disc.

Turn on the laptop again. Keep pressing the "C" key continuously as the system boots. This will enable the laptop to boot from the disk. Once the disk is accessed, the laptop will show

the message "Loading Files;" begin the factory reset process by always selecting the default option that pops up.

You can also use the "F12" key to boot from the disk.
Highlight the CD/DVD option and press "Enter" to begin the restore process.

Follow the on-screen instructions until the process finishes

Restoring a Toshiba laptop back to factory settings may take 30 to 45 minutes.

Unless you terminate a process by pressing "Cancel," your laptop will be rolled back to factory defaults, when the operating system installs completely.

hope this helps

My laptop turned off but it has 35% remaining battery


Laptop turns off suddenly? Computers may not be smarter than people, but if they’re designed properly, they will shut themselves down before overheating to the extent that they do themselves damage.

If the smart person keeps turning the notebook back on and figures out a way to foil the protection, the laptop is probably doomed.

Once a laptop shuts down for thermal event protection, it may refuse to power back up for a fixed period of time, five or ten minutes, or it may begin to boot and shut down immediately as soon as it boots to the point that it can figure out that its too hot.

The over-temperature protection is generally a BIOS rather than an operating system function, so one sign of an overheated laptop is one that shuts itself down while you’re using it and then refuses to boot as far as the operating system unless you leave it alone for an hour or so to cool down.

Unless you’ve been working in a very unfriendly environment, high temperatures, direct sunlight, etc, you should take even a single overheating shutdown as a warning to back up your data at the first opportunity and to give the cooling system a serious cleaning.

UNMOUNTABLE______BOOT_____VOLUME ***Stop: 0 X


It could be a problem with the harddrive and memories ,if you enter the DELL bios setup page when the computer starts up does it have an option to test the hard drive if so test it.
Also if you have two memory sticks then try with only one and vice versa.

Try booting with another boot CD like the ultimate boot CD it has some hard drive testing tools too.

Good Luck

Laptop keeps shutting off by itself


When you encounter about this issue this is overheating problem maybe the CPU fan is not spinning and faulty already, you need to check the CPU fan and replace a new one.

My Toshiba m205 4806 shuts down spontaneously. The lap top feels warm but the fan is running. any suggestions?


The cpu get overheated and will shtdown to protect it. The fan continues to run until a CPU safe temperature is reached / sustained.

1. Use laptop on flat surface, not on pillow, carpet, bed, etc. that will restrict air flow. Using a can of compressed air, clear the air vents.

2. If the symptom continues, then the heat conductive paste between the cpu chip and the heatsink is no longer effective (hardened, too thin, etc.). Remove the heatsink and add thermal paste
