MY HP PROBOOK 4530S DOESNT WAKE UP FROM SLEEP!

[usmanyo]

Hi guys i am currently using a HP PROBOOK 4530s i5 2.4 G, 1GB RADEON 6490M, 4GB RAM. the OS is windows 7 proffessional 64 bit. the problem i am facing currently is that my laptop when i put it to sleep or close the lid doesnt wake up from it, i mean i hear sounds of it turning on but nothing comes up on the screen! I have been trying to install the new ATI drivers since the ones i have are old and they are the only ones seem to be working as whenever i downloaded the latest version, they wouldnt work, couldnt switch between cards and it didnt show up! i did that and restored my windows a couple of times to get back to normal, then i upgraded my BIOS, as i thought that could help but it didnt! instead this new WOULDNT WAKE UP FROM SLEEP thingy started happening! ive tried a couple of steps to amend it but its just not happening, 

1 tried cleaning registry

2 triend using the powercfg command: it resolves the issue for then but afterwards it starts happening again

i am thinking about reinsatlling my windows, but wanted to make sure that this issue could be resolved any other way. i am really worried as i am afraid to put my laptop to sleep now! HELP PLEASE!!

I have the same problem with you, it's problem of F20, and still wait for HP bios update. Nothing to try now, just wait

Don't know whether this is still relevant for you, but I've just had a very similar problem with the ProBook 4535s. Couldn't get it to wake from sleep no matter what I did, and ultimately had to remove battery and power to kill it completely before rebooting.

I found a solution, which was to enable "Hybrid Sleep Mode" within the Advanced Power Settings of the active Windows 7 power scheme.

Might be worth you trying this if you're still having issues, though I hear there is now a new BIOS version for the 4530s, which may resolve the issue anyway.

Best regards,

Simon.

great, if the BIOS update is the problem, then why don't they pull the update down? i just bought a 4530s LAST NIGHT, and this morning wouldn't wake and i got a corrupted drive ecryption

i'm doing a system recovery now, but the bios can't be flashed backwards can it?

This might help.

haven't had the problem since system recovery. i did do the hybrid sleep thing, but not sure if that was the fix or the recovery was the fix.
