Hi Ken,
thankyou for your time, ok i will start from the beginning, i have recently started a collage course and needed a laptop, my son found this emachine e422 at a car-boot sale with a cracked screen, bought it and brought it home along with the power lead etc, I went on-line and purchased a new screen and fitted it and this is where i am at, no i have not actually seen it working, but from what my son tells me it has had some upgrade (maybe memory?) i have tried your F8 procedure but nothing has changed, it still fires up ,the screen goes to some list of text, as follows, nysydel-120 3.5 , system bios version v2.06 bios build date 12/02/2010 and goes on to say the rest of the system but only for about 1 or 2 seconds then reverts to the"Enter correct Password?" but that's where i think something must be wrong, the cursor that i would think should blink just stays frozen, i have nothing to hide rethe password and am happy to give you the serial numbers if you wish?, what do you think might be the problem? or is there anything else i could try, seems a shame to have to give up since buying a replacement screen,
