My T60 came in on Monday and everything is running perfect.

However I notice that even I charge the machine to 100%, I unplug the AC power, turn off the T60, the battery drops to 85% when I turn it on the next day morning.

I have disabled wireless.... everything in the T60.

Please advise.

Likely you are going into Standby mode, and not actually powering off your ThinkPad. Check the settings: go to Start > Control Panel > Power Options > Advanced > and check the settings under Power buttons.

Even if he were going into standby, shouldn't it last a lot longer than that? My friend has an Acer which says, in Power Settings, that it can last something like 147 days in standby.

Why not use the Hibernate option? Sorta works the same as stand-by, but actually shuts down the whole machine. I get around 10-12 hours stand-by time (with screen off).

It should. My T60 would lose about 6% overnight in standby mode, which I thought was already pretty bad.

A new T60 should lose much less charge than that. The battery might have issues.

I had the same problem and this being my first Thinkpad I too was puzzled.

Unlike Dell Latitude's or most other laptops, the Thinkpad will NOT go from "stand by" mode to "hibernate" if the AC Adapter is not connected. Simply, if you are running on the battery the system will go in to "stand by" but "stand by" will not switch to Hibernate.

The fix is in the BIOS - there is a where you must allow the computer to run "scheduled" tasks when running on battery. There is even a warning about enabling it. The caution - real but absurd - is that the hard drive will start up while moving the laptop causing damage. For the real world however the whole idea behind power management is to place the laptop in to "stand by" mode after a period of inactivity and then eventually "hibernate".

You need to go in to the BIOS and enable this to get the Thinkpad to act like a normal laptop.
