Im using sony vaio VGN-CR353, after installing w7, the battery display is not working correctly , all the times it shows low battery , but if i plug out , it works for one and half hours. the battery is working normally in my friends Vaio. what should i do?
That model does not seen to have Windows 7 drivers for it. The power management just can't read your battery settings. Do nothing, or install the original operating system if you really need to have the correct power meter settings.
Not every system can run Windows 7 with no issues, you need to check for compatability before installing.
