I cannot do a full hardware reset because originally it didn`t stay switched ON long enough to get into the BIOS.
I`ve tried removing all the power (battery + mains ) and keeping the ON button pressed ....to no avail.
------------------------------------------------------------------------------------
However, earlier this afternoon , I discovered that pressing the ON button rapidly for a few times (10 + ) kept the power switched on and the fans running ....but there was no response from the keboard ( No display on the screen and also the Number Lock, Caps lock, Scroll lock lights did not light up when the corresponding keys were pressed ) ..plus no response from the F keys to get into the BIOS....so this was another dead end....unless the keyboard is locked somehow?
I then thought about the BIOS so removed the CMOS battery for a couple of hours , then replaced it ...but still no response
I then replaced it with a new battery...but still no response.
(I also proved that the spare laptop screen was working OK by trying it in my other laptop...and it worked OK )
So I`m now stuck. I`m reluctant to try the HDD as I`m fairly sure that this spare one is faulty and caused all this trouble and do not want to risk damaging the working HDD or working laptop (again !).
Anyway, the laptop should respond to my Ultimate Boot CD on switch ON ...or at least show a display on the screen or beeps in the speaker ...but it doesn`t (I`d already proved that this spare laptop CD drive works OK in the other working laptop )
So there you have it. A laptop that now switches ON with fans running , but the keyboard shows no response and there is no flicker of any display on the screen or green "lock" lights on the keyboard (apart from the ON light)
Unless the keyboard is locked and there is a known solution out there somewhere that will tell me how to unlock it .
Does anyone know?
