- If you are unable to get it past the BIOS boot screen, you must have a hardware problem locking out the BIOS from completing.

Try this.

Unplug everything and remove battery.

Turn the machine over, uncover the hard drive in its bay, and remove it. Then try to reboot. If this does not fix it to allow you to enter the BIOS, shut down again and remove the memory and any other card from the system you find exposed on the underside of the machine.

When you reboot, you should either get a BIOS message saying the memory count is incorrect, or other memory error, or else a beeping sound from the laptop. If you do not get one of these, I would guess you either have a motherboard problem, or, possible, the keyboard, which is connected to the motherboard by a thin ribbon, has become disconnected.

If you get the beeping sound or a memory error, try putting the memory back in one chip at a time until you get a memory count and BIOS message and can enter the BIOS. If you put the memory back in and get the same error as before (machine locked, cannot enter the BIOS), it might be a memory problem or (more serious), a motherboard problem.

If you cannot access the BIOS to troubleshoot the problem using the above methods, you probably need professional help with troubleshooting the hardware, or need to find a friendly geek who can help diassemble the machine, test the keyboard and memory, etc. If you want to have a bash at this process yourself, post again with the results of the above process.

Good luck...
