Reload your sound card driver if you have one. XP has resident support for most sound cards, but not for all. . Short of that, you need to go to device manager and see if your sound card is showing up as "working correctly". If not, microsoft has articles that address sound problems. You should be able to get an answer there.

Try downloading this (The audio driver)
If that does not work, go to control panel and to "Audio devices and sound themes", Right-click on a empty spot in the window that pops up, and choose "Show disabled devices" and "Show disconncted devices", if you see a icon that is called internal speakers or speakers..something similar. You have to right-click it, and choose Use as default.

Sounds like your battery is dying and the unit is saving energy.
