Sleep mode not working

Do you have a model number for your you computer? That will help us find a bios update if there is one, I found one for mine on the HP website, and all the drivers, even though my computer came with 32bit Vista and I am now running 64bit 7. Also, you said your computer is a HP, if getting into bios is the same as on mine (a HP) you will need to tap the (esc) key a few times when the blue, circular HP icon appears when you first power on the computer. This will bring up a menu, press F10 to enter bios. On mine however, there is nothing you can change regarding sleep modes, it automatically detects the settings.

Hopefully we are getting to the bottom of this, Tim.

hey thanks guys i appreciate all your help.
i entered the BIOS but there was no option to change the sleep mode...and once again went to the hp chat, and the person told me to reset BIOS so i did that...

he also told me to reinstall power management...i guess i'll do that now...hopefully it will work this time!!!

My HP doesn't have a power management screen like the one you posted earlier either, from what I understand they are somewhat known for having a very 'locked down' bios.

Also had a look on the HP support site, and there seems to be no W7 support for the model of laptop in question, so no bios updates.

ahh tim how did you fix it so easily? we seem to have very similar laptops.
do you mind printscreen or tell me what you have for advanced power option screen with all the + sign open?? here's what i have that i think might affect it,

sleep
- "sleep after" (on battery 10 minutes, plugged in 20 minutes)
- "allow hybrid sleep" (on battery ON, plugged in ON)
Power buttons and lid
- "lid close action" (do nothing for both)
- "power button option" (sleep for both)
-"sleep button action" (do nothing for both)
Hard disk
-"turn off hard disk after" (20 minutes for both)

i wonder if those affect anything..but thanks so much !

Ok, so here are my advanced power settings;

Hard disk
Turn HDD off after (20minutes for both)

Wireless Adapter Settings
Power Saving Mode (Maximum Performance for Both)

Sleep
Sleep After (Never for Both)
Allow Hybrid Sleep (On for Both)
Hibernate After (30min on battery, Never when plugged in)
Allow Wake Timers (Never for Both)

Power Buttons and Lid
Lid Close action ( Do Nothing for Both)
Power Button Action ( Shutdown for Both)
Sleep Button Action ( Sleep for Both)

PCI Express
Link State Power Managment (Off for Both)


So there are my settings, Hopefully this helps.

i'm not sure what was the problem though, i fixed 3 things yesterday
i reset BIOS, then reinstalled the ACPI fixed feature button and reajusted what Tim posted earlier. and voila it's fixed FINALLY! thanks for all your help guys!
