Hi guys, I have a Toshiba Satelite C650 Laptop, it previously came with Windows 7 Home Premium. What I did, I did clean install of Windows 7 Professional, thus deleting the OEM that it came with. I have now a peculiar problem of having laptop charged upto 99% only and it shows Plugged in, Not Charging after that. I have to remove the battery while it is connected to power to get it charged. Support Engineer says, deleting the OEM caused it. Is it true guys? Please help me on this. Thanks in advance..
