Vostro 1400:System doesn't go to Hibernation when i close the lid

If you upgrade your operating system like windows xp to vista or windows 7. try to download sound driver compatible to your new operating system. And got to device manager and uninstall and reinstall the new driver.

Once any OS is installed over old one or clean install is done one of the drivers that has to be usually reinstalled is sound drivers. You will have to go to dell.com and choose support and downloads and find ur system and install the new vista driver. This should fix it. Good luck.

If your Vostro came with windows XP there's no way of restoring it to default settings. you can just manually reinstall XP. if it came with Vista. you can restore it by going to winRE. restart your computer. tap F8 repeatedly when you see the dell logo. select repair my computer. select keyboard layout (just press next). select your username and type your password if you have one. select Dell factory image restore and follow the prompt.
