Thinkpads Forum

I have a T61p, and this morning after using for only about 20-30 mins the battery had drained enough to force windows to go to hiberation. I plugged in my power adapter and tryed to reboot and nothing happened, no power indicators no lights at all. I checked all connnections trying defferent outlets as well as a different power adapter with no luck.
My T61p is still under warrenty; would something like this be covered, and has anyone else had this problem.

Just a quick update, after letting my laptop sit unplugged on my desk for a while, I took out the battery, plugged in the power cord and wouldn't you know it the power light came on. Put the battery back in and booted, and it is running fine. Although none of the open documents or programs i was using before the hibernation have remianed.
My system is set to enter Hibernation at 3% battery remaining. Is it possible that I have a faulty battery and 3% battery life is not enough to complete the hibernation process. If so how can I get it replaced.

Hi there. I sent my T61p for service and they changed motherboard. When I got it back I started with this annoying problem. Everytime I leave my Thinkpad in sleep mode it shuts down after a few hours or even minutes. Why? Then it stays bricked and cannot boot up from battery, I have to take out the battery and plug in the power cord to be able to boot.

I'm talking to lenovo and tomorrow a technician is suppose to phone me to find a solution. I'm afraid it has nothing to do with software and I wouldn't like to send my lapton for service.

I don't know wether you have the same problem as me but I think you should set your system to enter Hibernation at 5% battery level or even 10%.

Thanks, I have since set my laptop to go into hibernation at 10% battery remaining, and I've let it drain and shut off several times and each time it has rebooted properly. I think it had just failed to fully complete the hibernation process before the battery was dead. Although I don't understand why the power nor battery indicator would come on... any ideas?
I am hoping to get my battery replaced, but I don't know how to go about it. The battery information in the power manager says that my battery is at 29% capacity with a cycle count of only 71. The estimated battery run time is only 33mins.
I'm not very happy.

Your battery has probably gone bad. If it's less than one year old, it is covered by Lenovo's warranty and you should not have any problems getting it replaced.
But maybe there is also something wrong with your hibernation file or hard drive, if the actual hibernation process takes too long to complete. Have you tried recreating the hibernation file?
The reason I'm suggesting this is that I set my systems to hibernate when the battery reaches 0% and it has never failed, even when the battery is very worn (e.g., I did this with a A31p with 1GB and 2GB RAM, a T40 with 1GB, a T60p with 2GB and a T61p with 3GB (though, with the latter two the batteries are still more or less brand new)).

How long is too long? my laptop takes ~15 seconds to complete the hibernation process.
To recreate the hiberfil.sys file, I just disable hibernation, restart, and reenable hibernation? Also do I have to send my whole laptop in for lenovo to give me a new battery, my warranty doesn't run out until Febuary.

15 seconds seems reasonable. A good battery should not have any problems lasting that long with 3% remaining (as I was mentioning even pretty old batteries (like the 5 year old one in my A31p) can do it).

Your approach to recreate the hibernation file is correct.

You won't have to send in your laptop for a new battery. They will send the new one to you and may require that you send the old one back (though, so far I have never had to replace my battery).
