|If you have not re-loaded the orginally supplied software installtion, assuming it had Vista on it already, look for settings that affect how the computer behaves when you close the lid - in it's bios Setup, or in Toshiba specific settings programs, or in info about special keys the keyboard may have that may toggle that . That info should be in the User's or Owner's manual for your model |
If you have loaded or re-loaded Vista from a regular DVD, ACPI features such as Shutdown will often NOT work properly until you have loaded the drivers for the mboard's main chipset.
Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.
If you haven't used Vista for long, you may not be aware that that there are many things that have no RIGHT click functions in Vista like they did in XP and previous. That isn't significant unless you're sure you had RIGHT click functions to select from before for the things you're clicking on.
