Vista Tutorial - Power Options and Sleep Mode Problems

Hi everyone, Firstly thank you for the great tutorial! i have spent two weeks working on this issue and have finally resolved it. between this thread and some other sites i noticed a couple of people in this thread with the same problem behavior as me and dozens of them in Hewlett Packards forums. My problem was sleep mode would work fine once then the second time the monitor would shut down but the hard drive remained active and nothing would wake it. so i would shut the power button down and restart it. as soon as i pressed the power button it would drop into a proper sleep state and then reboot (almost like initially it got stuck half way dropping into sleep) like i say after reboot sleep would work fine once but not a second except when running solely AC power or solely DC power sleep malfunctioned straight away. anyway i tried everthing including formatting and reinstalling windows, updating bios and drivers, different power modes, setting bios back to default then today i opened the case dropped out the cmos for 10 mints problem still there so i removed the memory sticks put only one back PROBLEM SOLVED! put the second stick back in problem back again so all along the problem was one of my memory cards even though no memory problems were displayed in sys. info or with windows memory diagnostic tool. well i hope my experience can help someone else who has not yet resolved thier sleep problems (or mabee check the easy things before reinstalling windows like i should have)

Thanks Brink for the help, unfortunately it did not change the behaviour of the hybernation. The battery was 86% when the computer was put into hybernation using the proposed shortcurt holding shutdown -h and 81% after 5 hours which means the hybernation mode is still S3 type and does not perform a full save to disk. Any suggestions ? At least it is a good opportunity to discover further your tutorial which are very helpfull. Best regards

Hello Mitchell,

You might see if there is a "Memory Mapping" option in the BIOS that you try with it enabled to see if that may help.

However, you might consider flashing the BIOS back to the older version since it work perfectly with it. Be sure to send a report to your motherboard's manufacturer about that bug in the BIOS to see if they may be able to fix it in the next BIOS release. They may also already know of this bug and have a workable solution for it to.

Hope this helps,
Shawn

Hi i am back again and am really at a loss and hoping this may trigger something for someone. i obtained a replacement memory card and the problem was back again now i have tried all different configurations for this and come up with the same results basically:
1Gb of ram sleep mode works fine.
1.5Gb of ram sleep mode works once ok then after that it fails as per previous post
2Gb of ram sleep mode doesn't work at all.
This problem seems to have arisen about two weeks after i did a bios upgrade as prior to this i had no problems and had operated on 1.5Gb of ram for over two years, I only have option S3 and says other options are not hardware supported I re enabled hibernation today it did not make any difference although it works ok. am not really expecting any miracles on this as i have exhausted pretty much what everyone else has tried i just thought that the memory card thing might jog something in someones memory, here's hoping.
