HI friends, I have this lenovo laptop and I have been using it from a while it was working great but since few days I confront a problem in it that my lenovo laptop is shutting down by itself I checked for the battery too even if enough charging is remaining it is shutting down unknowingly what might be the reason I don;t know.Please help me fix this or I need to change its battery?
First, try to use the computer with the charger installed. If the problem is still present, we will know that this is not related to the battery itself. Batteries should last between 12 to 18 months, depending on the rate of usage. If there is no problem when using the charger, you will have to replace the battery.
Also, this can be an error in any of the drivers installed. Go to device manager, by right clicking on My PC and then clicking on Administration. You will enter to device manager and check if there is any yellow flag. A yellow flag indicates that there is an issue with that specific driver. If so, right click on the driver with the yellow flag and delete it. Restart the PC and if this is Windows 7 or 8, the driver should be installed automatically, if not, go to the internet and try to look for the driver to download using the description of the device with the yellow flag.
If the problem is still present, try to enter the self tests of the Lenovo. In some models, you have to press F10 during starting up to run the self tests. Pay attention to the hard drive and motherboard test results..
If you are using a laptop and it keeps shutting down automatically, the most common cause is overheating. This is a common problem with laptops. The easiest way to fix it without getting it serviced to replace the cooling fan is to use a cooling pad and you can buy them easily online. Check this one on eBay: USB Cooling Big Fan Blue LED Light.
