Mere laptop mein usb nhi kaam kar raha hai

Hi @vishalsing19054

Plug in a USB device which indicates that power is being delivered from the USB port, e.g. a mobile phone or USB mouse with a laser light. It doesn't have to show that it is connecting to the laptop it only has to show that it is charging or that power is connected.

If it shows that it is NOT charging or has no power check the following setting:

Go to Start > Control Panel > Device Manager > Universal Serial Bus Controllers > click + to expand the list > scroll to first USB Root Hub entry > right click on the entry and select Properties > Power Management and uncheck the box (if it is checked) next to Allow the computer to turn off this device to save power. Click OK

Do this for all the USB Root Hub entries.

Restart the laptop and when it has booted to the Windows desktop see if:

a) there is power being supplied from your USB ports by plugging in the phone again,

b) that USB devices are being "recognized" when they are being plugged in.

If it shows that it IS charging or it has power but is not being recognized do the following:

Go to Start > Control Panel > Device Manager > Universal Serial Bus Controllers > click + to expand the list > scroll to first USB Root Hub entry > right click on the entry and select Uninstall. Do this for all the USB Root Hub entries. Be aware that after you do this, that the USB ports will not work until the laptop has been restarted.

Restart the laptop and allow Windows to find your USB ports and reinstall them. Wait until the HDD activity settles and then test that the USB ports are working correctly.
