Assuming your laptop has a NiCad battery, they develop a memory effect; if you always have the laptop plugged in when you use it, you are only using the battery in a charge state from 95% to 100%. After a period of time, the battery "remembers" that so from fully charged to fully discharged is effectively only 5% of its capability. Not using it for 12 months will probably have killed it completely.

For future reference, with any NiCad powered items, use them until almost fully discharged, then fully charge them. Best still, buy items with NiMh batteries, thay have no memory effect!
