Randomly shutting down

Hi katrina1331, From what you describe it could be a couple of things but the two the come to mind first are power and perhaps overheating. The fact that you can?t run on battery power very long would suggest it can?t hold a charge or much of one or the AC power adaptor or charging circuitry aren't working correctly. To proceed I need to get some more information from you: Are the A/C adaptor and the battery the original ones and how old is the laptop? There are several LEDs on your laptop, (we?re going to ignore the touchpad light and the wireless LED), a power/standby LED to the top left of the keyboard three just below the touchpad. The left LED is another power/standby LED, the hard drive LED in the center and the battery LED on the right. -What are they doing just before the shutdown and immediately after while running on A/C power? -What are they doing just before the shutdown and immediately after while running on battery power? Try running the laptop with the battery removed and the A/C adaptor plugged in. Do you notice any change in running time? With the battery and A/C power plugged in click on Start, Settings and then Control Panel. Find and double left click on power options. A box labeled Power Options Properties will open, click on the tab labeled Power Meter. It should indicate the battery is at 100% or that the battery is at some percentage and that it is charging and running off A/C power. Let us know what you find. When you first start up the computer run your hand along the bottom of the laptop, especially along the four screened vent areas, to roughly gauge the laptops temperature. Use the laptop in a way that causes it to turn off and then run your hand along the bottom surface again. If the laptop is hot, to the point where it is uncomfortable to touch, then overheating may be a factor. Let us know what you find out and we?ll continue.
