my vaio's battery care function missing so that I check some drivers in the device manager there is a driver intel 6 series/c200 series chipset family thermal control but it doesn't work properly when i check it it gives me this device not working because of a resource problem (somethin like that) and this device sometimes comepletly gone ..
why it is happening? whats the problem .. if it's a hardware problem i will send it to the service...
This driver could be any component integrated on your motherboard; I recommend downloading and installing the latest Chipset Software Installation Utility;
If it does not work, contact your computer manufacturer for troubleshooting assistance.
