I am sorting out th chaos of a young relative's Toshiba laptop!!!
It has W7 Home Premium 64 bit. The charging symbol in the system tray disappeared, and on trying to restore it by the normal method (Rt click in tray, Properties, Customise, it is greyed out (as is the volume icon). I tried the Google suggestions including regedit and MS Fixit, but still it will not show. A similar laptop is fine. Any ideas? Problem is the PC goes dead if the battery is not monitored to see if it is charging. I have used the Toshiba tool, but this is not on continuous show.
Have a look in Control panel, Notification area icons, and click the link at the bottom left " turn system icons on or off". Or click the up arrow and "customise" in system tray will bring up the same page.
Thanks; will look later. This young relative's PC is a nightmare- cleaned up most issues. Still to try to find a solution that windows updates fail to install - tried CHKDSK and sfc /scannow...without success.
