E6500 Wont stay asleep

Hey guys haven't been around in a while but I have an unusual problem with my Latitude E6500. This started a few months back for an unknown reason; I didn't make any large Hardware or Software changes, when I put my E6500 to sleep (either closing the lid, hitting power button, or going through menus) the machine will either not sleep or won’t stay asleep. I noticed when the unit is plugged in it starts to sleep for a few seconds and then the CD/DVD drive lights up and it just stays on with the screen blacked out. I have had better luck with the Unit unplugged although occasionally I have come back and found the unit on. I am Running XP Service pack 3 With an Intel core duo 2.40 GHz processor and 2.95 gigs of Ram I also have the 250 gig HDD with the bog standard screen and graphics card, the machine lacks a fingerprint scanner and webcam with the only extra being the Backlit keyboard. I had to clean install the machine around 7 months back because of a virus, however, for an entire semester I didn't have this problem, because of my clean install I don't have a regular log in screen just the small Username Password screen because of a conflict with msgina.dll This doesn’t seem to have anything to do with the problem and I am thinking of getting rid of msgina.dll since it doesn’t seem to be a part of Symantec Endpoint. To try and Resolve this I installed BIOS A22, which obviously didn’t help. Anyway if anyone can help that would be great I am at a complete loss. Thanks

 

Try looking in the logs in Event Viewer (My Computer > Manage > Event Viewer). This may provide some useful clues about what is waking the computer up.

You should also go through the power management options of devices in Device Manager and disable any "allow this device to wake up the computer".

In Event Viewer all I get are some old crash reports no active logs, Do I have to look through every single device in device manager to determine power usage all I see is Power Capabilities under details. TO give a heads up I removed msgina.dll (no problems and got the welcome screen back)

 

Specifically check the network and modem devices.

Also look in Task Scheduler for tasks that have a regular schedule with a time when the computer may be sleeping. I have also seen cases where the sleep to hibernation time-out wakes up the computer and it waits for a password before it can hibernate.

Personally, I rarely use sleep because it is too easy for programs to wake the computer up. A hibernating computer usually stays off until the power button is pressed.

Thanks I have reset my settings to hibernate and that seems to work fine at least while I look for whats causing the standby problems. At least now I don't have to worry about the damn thing turning on while its in my bag and overheating. Thanks alot so far

 

Use the GUI to switch to the problematic power scheme and then try:

powercfg.exe -devicequery wake_armed

Run this command from an elevated command prompt (admin privs).

In theory the command above should list all devices currently configured to wake the system from any sleep.

Read the command help first:

powercfg.exe /?

Good luck.

 

Sorry for being relatively computer illiterate (think hooked on windows phonics for this ex mac user) I ran powercfg.exe from the run menu and a black command prompt screen popped up and closed, then I ran "powercfg.exe -devicequery wake_armed" in command prompt (I believe thats what you wanted me to do and it said)

Dell Wireless 1397 WLAN min-card
Intel<R> 82567LM Gigabit Network Connection

Does this means both the wireless card driver/Ethernet driver are waking the system? Or did I do this incorrectly? I am running control point, I should also mentioned that msgina.dll reinstalled itself I manually deleted it with no problem and I get my welcome screen, also it seems the unit will not wake from hibernate, when it is left unplugged I was on the road the past 2 days I didn't plug in my laptop and it remained in hibernate mode for long stretches (12+ Hours) Thanks again for the help guys it definantly deserves a couple of pints

 

I just went through event manager and its seems both these devices were allowed to wake from hibernate I am going to try standby and see what happens

 

Wow this seems to work with standby thanks guys I'll give it 24 hours to see what is up but so far so good I got 30 minutes in standby plugged in previously the machine would wake up in under a minute

 

It means either network interface (device) is capable of waking the laptop, if network activity is detected.

They are enabled somewhere, otherwise it would remain in hibernation.
