Thinkpads Forum

Hi everyone.
I just want to know whether this problem be solved or not.

I have a X61 tablet (7767 01u) / L7500(1.6GHz) / 2Gb ram / Windows xp 2005 for tablet.

I have the same problem. BATTERY DRAIN when standby or hibernation.
I will loss nearly 30% (Standby) battery power overnight. When I follow this thread and turn off all the wake-on-lan from BIOS and Device manager, I still loss 13% overnight (Standby), (But thanks! much better than before! AHA!)
I saw there maybe a setting for vista (HD audio controller?), but I cannot find that for XP.

I am using Active Protection System v1.71, I will try to use v1.53.

ps: I have a T43, standby over one week will just lost 3% battery.

Hibernation is different from Standby in terms of Windows terminology. It's normal that the battery drains if the PSU is not connected during Standby, as power is needed to keep the data in RAM intact. The 13% figure sounds normal to me.

Are you sure your T43 is in standby mode? At first brush, I would say 3% for 1-week seems like it's in hibernation instead of standby.

Cheers.

After weeks of trying, I *finally* solved my problem. I have an x301 that was eating through 100% of power in 12 hours on sleep and hibernate. First, I ran the powercfg command line switch to figure out what devices were set to wake the computer... in my case it was the HID compliant mouse (what?!?). I turned that off, but I actually don't think it's the main issue.

The main thing that solved the problem was that I made sure that before hibernating or sleeping, I removed the computer from the a/c power source. Basically the issue seems to be that the thinkpad doesn't switch power plans unless you unplug it first. So the easy way to fix this is to unplug the computer (you'll hear a beep if you have the power options set to "beep when power changes") and *then* put the computer to sleep.

If you put the machine to sleep before unplugging it, it appears that the machine still thinks it's in ac mode and continues to eat power with wild abandon.

Posting this in case it helps anyone... this was absolutely driving me crazy before, as I love everything else about this machine.

Chanel,

The wake timers is the culprit draining your battery while your PC is in hibernation. Try the following fix:

1. In Control Panel, Run "Lenovo's Power Controls" (Power Manager v3.2)

2. Under Power Plan folder, select "Energy Star",

3. Click "Restore default settings".

4. Under "Advanced settings"-> "Allow wake timers:",

Select "Disable" for both Battery settings and AC settings.

5. Under "Advanced settings" -> "Wireless adapter settings" and "PCI express"

Select "Maximum power savings".

6. Click "Apply" and "OK".

interesting, i did not know that, its essentially standby, with backup.
