Battery runs flat. Laptop "hibernates" without warning. Starts up again immediately.

Laptop hibernates, and then starts up again immediately, like it was switched off?!

Hi guys.

Anyone able to shed any light on this?

My Optimus II doesn't seem to be able to hibernate anymore, when i'm sure it did a week ago...

I hibernate the machine, or it hibernates itself when the battery is flat... The screen goes black, and you expect it to hibernate... once it's "hibernated" it wakes back up immediately. The "Style Note" splash screen appears, and along the botto, says "Returning from hibernation......" or something... I then get a windows error recorvery screen, asking if I want to go into safe mode, start normally etc. - seems it's failing to hibernate... despite plenty of disk space on the windows partition etc.

Not normal that it wakes up on it's own after supposedly "hibernating" either, and a problem, as if the battery is low, and it's hibernated itself it'll sometimes die completely before getting me to the login screen... Do you think these two problems are related?

Could this be related to it waking itself up from sleep on it's own sometimes, completely randomly, often in the middle of the night? I will check Wake on LAN setting in BIOS and report back.

I'm sure it's just some software problems I can fix, but I don't really know where to start!

PS. According to advanced power settings it should hibernate when power level is critical, but do nothing when battery level is low. It should warn low battery at 15%, which it has started to do again, thankfully... I'm reluctant to plug in at 15% though, and wear the battery quite a bit, bit it's ever so easy to get carried away and forgot to when the battery is more empty, especially when you're busy... and with it losing my session, I could easily lose my work!

Any ideas much appreciated.

Thanks in advance,

Matt.

I fiddled with the advanced power settings, and the laptop does now give a low battery warning on 15% battery... yet I still have problems.

The screen goes black, and I expect the machine to hibernate. It seems to. It then switches itself back on immediately, and then tells me Windows has had a problem, and asks me if i want to go into safe mode, start normally, etc. - I select start normally, and the machine boots up, like it's shut itself down, and starts a completely new session.

Why is it switching itself on immediately when I hibernate it/it hibernates itself? Sometimes it dies before it's booted up windows/before i've got the charger, when it has hibernated due to critical battery level.

It's not hibernating properly, and failing to resume, despite the splash screen saying it is resuming windows... It's also still trying to resume immediately after it's hibernated?!

Any ideas?

I've seen this type of issue occur before due to driver issues.
Unsure if this would be where your issue with hibernation is but would recommend if not already done in making sure all drivers are up to date as well as the BIOS just to try to rule these out being the culprits.

Right click on your “My Computer” then select Properties.
Click Device Manager on the left side of the Properties window.
Check your Network card on the Network Adapters (Click on the + sign to expand).
Right click on your network card and select properties.
Go to the Power Management tab and untick the option there to prevent your network card from ever waking up Windows.
To find out for sure what event/device woke up your Windows from its last sleep state, go to command prompt (type cmd on the Run/Search box and press ENTER), then type this:
"powercfg -lastwake" or type "powercfg lastwake" (without the quotes) then press enter.

Thanks for the suggestions. I had already tried yours Vanthus, and it's already unticked

I'll turn wake on LAN off in the BIOS though... it woke itself up the other night when I left the uni network ethernet cable plugged in... not sure if it does it when it's unplugged yet, will have to keep a closer eye!

I'll troubleshoot drivers when I have time Paul, thanks.

I just gotta get the hibernation issues sorted, sometimes resuming fails... sometimes it seems to work... I think it did today. It went flat, and resumed the system after hibernating... it did do it immediately though, which is stupid, and very annoying!

I need to keep tabs on it's behaviour better I think, so I can troubleshoot it better.

I'll be back with some proper findings soon!

Today, disconnected from the ethernet, and with no wi-fi networks available, it woke up at 12.30pm, from SLEEP, and popped up the resuming from hibernation splash screen... it then failed, asked if I wanted to start windows in safe mode, normally, etc. and booted up a fresh session...

What the hell?

Since it did a fresh restart though when it woke itself, and tried to resume from a hibernation image that I presume wasn't even there, it won't have recorded this wakeup properly will it, cause it essentially rebooted itself?
