Shut down, remove the AC power, then remove the battery unit. Put it back on AC power, boot and what happens?
i've been using an external (logitech) keyboard & mouse for 2 years with my compaq v6000. NO PROBLEMS until yesterday. the keys on my laptop don't do anything. the touchpad light is ON & the cursor moves until i touch a key, then nothing!
i've tried trouble shooting, but everything is "fine".
just before this, (hours) i was unable to shut down the computer properly, then it didn't want to start. i told it to use the last good config. same problem a little later & i started it in safe mode. it is still taking a LONG time to start up & the keys & mouse don't work. i've done several scans (kaspersky & webroot), defragged, disk cleaned, you name it.
i don't know if the two things are related. any ideas would be helpful. i DO move my laptop, but CAREFULLY - i have a hardside case,etc & have not spilled anything, etc.
