First try unplugging and removing the battery, press the power button for five seconds. Leave it for two minutes and try the USB again. If that doesn't work, remove all USB devices.... Restart in Safe Mode* Open Device Manager, click Start, and then click Control Panel. Double-click System. On the Hardware tab, click Device Manager. Double click 'Universal Serial Bus Controllers'. Right-click every device under "Universal Serial Bus controllers ", click Uninstall and click OK for each instance. Don't worry, Windows will re-build them. Restart normally and try again. *Note: On start up (before Windows loads) keep tapping either F5 or F8 (be aware that some manufacturers use F8 for system recovery!) then use arrow keys to highlight 'Safe Mode with networking' and hit Enter/ Return, click on a user account, enter the Administrator password (if you don't know it, there probably isn't one so leave it blank) and hit Enter/ Return. ©Techno |
