Why is my laptop not booting

Hi,

Firstly 2 beeps indicates a system board problem, nothing specific is mentioned.

Have you tried turning it on with the power adapter connected and switched ON?

If so and it works you may have a battery problem.

If it doesn't, try the following:

Disconnect the AC power adapter, then remove the battery pack (Section 5-5 in the attached link) and finally reseat (i.e remove and reinstall) the memory module(s), (Section 5-10 in the attached link).

Reinstall the battery pack, connect the AC power adapter and see if it comes on.

If not, unfortunately you have a problem with the motherboard. here is a link on how to remove the motherboard.

Compaq Presario v2000 mother board Replacement

You can go online and find replacement motherboards (check your motherboard version) but given that the PC was released 10 years ago it may not be worthwhile fixing and you may be better off buying a new replacement PC.
