Battery/AC power display error

[dworley]

Hi,

I have a Toshiba X305 laptop which thinks it's running on battery power when it's plugged into AC power and says it's plugged in when it's not. The only exception is when it gets low on power and I plug it back in, it says it's plugged in and charging. Once it reaches a certain threshold however (about 90% charged), it reverts to the "battery power" icon.

This problem began when I installed Windows XP instead of Vista which it came with.

Any ideas on how to fix this?

1. 

I have a Toshiba X305 laptop...

Is this a Tobshiba Qosmio X305 laptop?  And if so, which one:
    X305-Q701
    X305-Q705
    X305-Q7051
    X305-Q706
    X305-Q707
    X305-Q708
    X305-Q710
    X305-Q711
    X305-Q715
    X305-Q720
    X305-Q7201
    X305-Q725

2.  After you installed Windows XP, did you go to the manufacturer's website to download and install the motherboard drivers?

It's a Q725.  I have installed all of the drivers.  Some are from Tosh.  Others are fromt he orginal manufactorers  No unknown devices.

Well you might take a look at the following two links.  The first one addresses similar problem with Windows ME and Toshiba models available in the year 2003.  It was resolved by installing "Toshiba Power Saver Utility".
    Microsoft AC/DC icon on the task bar does not change when power changes are made

The second link was closest download (30 June 2008) I found that refers to a Toshiba Utility.  It is applicable to your operating system and Toshiba model number, but I was unable to find description for what it does.  I think this download is worth a try:
    Toshiba Software Upgrade for Windows Vista / XP

Since laptops contain proprietary hardware, it might make sense that Toshiba would provide a utility to address power status.

Basically, I think you're pretty much on your own unless you want to talk with a Toshiba representative.
