Re: Toshiba M400 Battery 100% but when power disconnetced...
Hi I am Vortash .. firstly take the battery out entirely then put your adapter in and boot up if the charge light is off you can safely assume the computer is fine .. batteries have a shelf life and an internal memory , they tend to do strange and wonderful things when they reach old age lol one of them is telling lies it says it's full when it's empty .. you will probably find a cheap replacement on Ebay or Amazon and I think you will find that will cure your problem .In the event the first test was a bust and on your computer the charge light still came on .. then you should take it to a service department for a free estimate they will tell you whats wrong and if you don't get it repaired there you can ask on here how to repair it ?. regards vortash

This is the procedure for solving consider replacing
your battery problem. Start by running the command prompt with administrator privileges.
This will give the full control over the command prompt. There are those
commands that can only be executed when you are using the command prompt with
administrator privileges. Change the destination path showing on the command
prompt to be set to C:\ then type the command POWER -ENERGY( to change destination path to C:\,
type CD\ ). This command will make the computer scan the battery status and
after 60 seconds, a report will be generated and saved in C:\. Simply open the
energy report and scroll to check the battery information. Look for the design
capacity and the last full charge, note the difference in this figures.
For my laptop, these were the details Battery Information
Battery ID: Hewlett-PackardPrimary
Design Capacity: 88800
Last Full Charge: 36467
To remove the message consider replacing battery fully charge your laptop battery then unplug the charger to use the laptop on
battery power. Use it until the laptop
to automatically shut down. Still with the charger unplugged, power on the
laptop again. Do this until the battery is totally empty. Now plug in your
charger and charge the battery fully. Then perform the commands steps again by
running the POWER -ENERGY command. Make sure you note the differences in the
last full charge details. Continuously perform these steps until the figures in
the last full charge are more than 40% of the design capacity.
I own the Toshiba NB505 netbook and the very same thing was happening to me. Here is what I did to fix my issue: Step 1: Shut down the computer and remove the battery. Then turn it on but now with the battery out. It should say "battery not detected". Step 2: Open control panel and open the "device manager". Under "batteries" (the first one), uninstall the one that says "Microsoft ACPI Compliant Control Method Battery". This is the battery driver. (Don't worry. The computer will automatically re-install it) Uninstall the driver and shut down the computer. Then reinsert the battery and power on the computer. The driver should have re-installed itself. Check to see if the battery is now charging. (It will take awhile for it to fully charge to 100% Best to shut it down and let it charge. The far left indicator light on the front of the Netbook will turn green when it is fully charged) Hope this helps. Yeah I had to figure this one out on my own. Toshiba support staff over the phone were useless! Good luck!!
Have you seen inside a laptop battery, it's not just a battery. It also has control circuitry inside, could be that. Not usually repairble but you can do some makes of battery. See here:Circuit. Personally I would buy a new battery.
Here's a link for Toshiba's UK site. I looked around a bit and they don't seem to offer much in the way of drivers. You might try driverguide.com I've found it to be a good place to find those hard to find drivers, plus it's easier to use than most manufacturer's sites.
It sounds as if the power pin (where the AC cord connects to the computer) has been damaged. The part to fix it usually runs under $10 but the labor is gonna set you back $100-200.
Because the connector pin is so fragile, the damage to the pin is caused by the day to day tugging and pulling on the power cord.
What you needed when you got the computer is a cable stay or cable retention device like the Jerkstopper. It takes up the strain when you yank or **** the power cord and minimizes the damage to the power pin. It's a very common problem with laptops.
Here's a short video that talks about the problem. . . .
