hp windows vista sleep problems help

i have a windows vista hp pavilion dv6000 laptop that goes to sleep fine but will not wake up. It has been doing this for a while (over a year) but i do remember when it first started doing it if you opened and closed the lid a few times it would resume, but not anymore. when you press any buttons move the mouse via built in touchpad and keyboard the light just keeps blinking and never resumes, and holding down the power button for any amount of time does nothing. the only way to make it reboot is to unplug and remove the battery and restart. i have tried many things, like turning off hybrid sleep and looking at command prompt power settings, originally hibernate wasn't an option but i managed to turn it on and it still works fine. i have searched and most of the threads i have found are pretty old and the problem was usually a little different. please help
 
This is a common problem with HP laptops.

The best solution I have seen (one recommended by HP) is to do a hard reset:

Performing Hard Reset

1. Turn off PC

2. Unplug both battery and ac adapter

3. Hold Down on the power button for 30 seconds

4. Plug everything back in and turn it on.

When you are back at your desktop screen, change the sleep mode and display settings to 1 minute to see if you can wake it back up.

If not, then load into your BIOS by pressing F10 during boot up. Once in BIOS, press the F9 key and select "load defaults". Once you load defaults, press to F10 key again to save changes and exit. After that, search the hp website using your product # on your laptop to see if there are any BIOS updated for your product.
 
kmkrreeves1,

Sorry to hear that you are having issues with your notebook. Do mind letting us know if the excellent instructions you received helped to resolve the issue?
 
thanks for the suggestions but none of them worked. I did the hard reset and no result, reloaded the default bios configuration and looked for bios setting for power but found none, and there aren't any updates from HP, I'm thinking it must be a hardware defect.
 
if anyone is reading this and has a similar problem, the answer is simple-there is none, and anyone willing to help seems to mysteriously disappear so good luck. and the laptop i'm talking about the lcd went out and its not worth fixing so there is no need for sleep (and no one is willing to help with that either)
