X61 tablet battery drains fast in Vista?

[ronan_zj]

my X61T is using vista Business, and i notice after overnight in standby mode, the battery drops from 100% to 85% in my bagback.
I am wondering if its common on your tablet?

In terms of idle power usage for Vista modes, here is how it goes:

Some used by Sleep
Least used by Hibernation

Of course, there is an inverse relationship to how long it takes to resume computing from each mode to how much battery life is used during that mode.

That's why I would plug in the laptop during overnight, or simply shut the unit down entirely and let the unit get a full night's rest

I generally keep my battery out when I am plugged in. Just for heat issues and drainage anyway.

If I remember correctly (at least; what I think it is, looking to the battery information tab of power manager), Lenovo's Power software just bypasses the battery if its full and plugged in - it just says "not active", so if its a little bit smart (and I hope it is...), it will not use any of the battery....

Haven't tested sleep-consumption though...
