A shut down the computer every night. When I wake up in the morning, the computer is already on. In general, after is turned off, it will self restart after a few hours. I looked in the BIOS setup, but I couldn't find anything related to self-restart settings, or wake-up on modem (is not even connected to a phone line), or wake up on LAN (it is connected to a wired hub, which is connected to a router). There is no other computer on the network that is on at the time it wakes up by itself.
Please help me to save some energy!

Open Control Panel, Power Options, set to High Performance, open Change Plan settings, open Change Advanced Power settings, set Sleep and Hibernate to Never, adjust advanced settings to your preference. Always shut down your computer when not in use, it will last longer, If you don't have a UPS, will help protect against power surges.
remove the ram( memory) and clean with a dry cotton cloth and make sure to insert it properly and after the first display go to setup useing f2 or f10 depends on the laptop model and load the deafualts. i think this may do the job
To wake it up,first try just quickly pressing the power switch on front. If worse comes to worse,just turn it off by holding the power button in until the pc shuts down & simply power it back on. Then you'll be able to get into windows & make the proper adjustments for the power settings you want & be able to configure the keyboard to put the pc to sleep or wake it. The above link is straight from hp,reguarding the same issue. I gave it to you for reference.
k when the computer first boots up hit f8 or shift f8 to get to advance options . move arrows to last known good configuration. if that fails to get you on desk top you will most likely need to call hp and get replacement disks to reinstall the missing or currupted drivers. your NTloader is not reading from your master boot record that is why your getting this.
There is a lot of controversy over this issue, and it depends on how you use your PC. I use my PC for business, from 8-16 hrs a day. The best time to scan for viruses and perform other maintenance tasks is when I'm not using it, which happens to be while I'm sleeping. I set my PC go into hibernation, so it will 'wake up' at 3 a.m. and perform the full virus scan. There can also be problems with 'cold starts' on your hard drive if you turn it off every night. My recommendation is to leave it on, but make sure you have proper energy savers for the screen and hard disks on so it doesn't waste power.
IT is really easy.
Open the side of the computer and on the motherboard you will see a flat silver disc about the size of a quarter.. a little smaller. Take it out and take it with you to radio shack/Wal-Mart or where ever, to get the right replacement. IT just slides back into place.
Sleep on Vista is a combination of Standby and Hibernate. First it will go into Standby and then later if a laptop it will go into Hibernate. Any movement of mouse or keyboard may cause it to wake up.
Some computers will wake on Lan. If you have ethernet connected this may be the cause. You can turn this off by using Device Manager - Hardware - Select ethernet adapter - driver - Advanced - look for Wake on Lan and Pattern Matching and disable this.
ALso check your BIOS settings and disable all Wake on XXX settings.
