  • F1
  • F2
  • F12
  • ENTER key
  • ESC key
  • ThinkPad key
  • removing PSU then rebooting
  • or someone has even suggested (for windows 10 UEFI only) “C:> shutdown /fw /r /t 10”

USB 2 v USB 3 or 2 USB 2 or not 2 USB 3

USB 2 v USB 3 or 2 USB 2 or not 2 USB 3

To get maximum performance out of your USB peripherals make sure you plug USB 2 devices into USB 2 sockets and USB 3 devices into USB 3 sockets

For example is a waste to plug a mouse into a USB 2 socket and you can increased your USB 3 disk drive from 30M/s to 80M/s if its plugged into a USB 3 socket.

So how do you tell ?

  • USB 3 sockets are often BLUE
  • Run Device Manager and Order by Connection
  • Use a hdd case that has a power light showing you the speed (the SALCAR SATA USB 3 case power LED glows WHITE for USB2 and BLUE for USB3)
  • Manually test transfer speeds in different sockets
