When I boot my machine the keyboard and mouse are totally irresponsive. Yet, it does not happen at every boot, only on most boots.

I then restart the machine (often several times) until it starts in a different state and the mouse and keyboard become responsive. I am clueless as to why my mouse and keyboard work only sometimes.

My machine is a Toshiba Satellite c670/c670d laptop, I am using the default in-built keyboard and (synaptics) mouse.

Any logical solutions welcome.

    Wait, this is pretty hard to understand. Is your mouse/keyboard switched off on a laptop? Is it an external mouse/keyboard (or just the inbuilt mouse/keyboard of the laptop)? What do you mean by switched off? Do you mean that it does not give characters when typed or the mouse does not move. – grochmal Aug 21 '16 at 19:10
  • Just the internal mouse/keyboard, and because the machine is therefore totally unresponsive the only option is to switch off and then on again. – Jmorrison Aug 21 '16 at 19:18
  • That is much more likely a BIOS/UEFI/hardware problem, than kernel. And definitely incredibly difficult to debug. Nevertheless, the first thing i'd try is to repeatedly enter the BIOS/UEFI menu (across reboots) and see if I can replicate the issue inside that menu. – grochmal Aug 21 '16 at 19:33
  • Could you please rephrase your question to make it easier to comprehend? – ABcDexter Aug 21 '16 at 19:57
  • Sometimes when I start the machine there is no pointer movement or keyboard response. After switching off and then on again, usually twice more, the pointer will work as will the keyboard. – Jmorrison Aug 21 '16 at 20:27
