However, all was not completely rosy- on switching on, it would load the BIOS screen (with the blue Dell logo) then switch to a white/grey screen with the following text:
Dell Inc.
The computer system #XXXXXXX-XXXX is protected by a password authentication system. You cannot access the data on this computer without the correct password.
Please type in the system or administrator password and press enter.
This looked pretty damning, I presumed the primary drive had been low-level formatted, or something similarly destructive. A cursory web search brought up a few forum posts on this issue, seemingly all from people who had ‘bought second-hand laptops’.
I purchased a cheap USB caddy from local shop, Computer Orbit, put the laptop hard-disk in it and tried to access it from a couple of other computers- with no success; it just seemed to appear as a corrupted or blank drive.
I phoned Dell technical support (an overseas call-centre). The first-line support couldn’t get a handle on the problem (“…so this is Windows log-on prompt, yes?”), but to his credit, quickly knew to pass the call upwards. The second-line support guy was very helpful and, after a few questions to validate my identity, eventually offered the two passwords I needed (one initial system password and one primary HDD password).
To my surprise (and joy!) the system now boots straight into Windows, as before, with all user accounts and data still intact. I still have no idea what happened to the laptop while it was away- perhaps a battery was removed? Certainly the system clock had reset.
Call time: circa half-an-hour. Out-of-warranty support call cost £30 (though a year’s support was offered for £109). End result: priceless!
One strange positive to emerge from this escapade is that when I took my laptop apart I discovered it had an empty bay for a second hard-drive, which could be a very easy way for me to grab some more storage space on my overloaded system!
