Laptop Freezes when AC Cord is plugged in.

Specs: Windows XP Processional SP3, 2.80 GHz / 256 MB
Hey ALL you experts out there,
I have a major problem with my laptop (OK, maby not that major but its irritating)
It's a Dell Latitude 100L (quite old i know),
This is the story:
I got this laptop from one of my buddies he sayd it doesn't boot up and can't charge so I took it and upon getting home i plugged it in and waited 30 Min, I tried to start it but it only lit the screen and in the top left corner there was a blinking (underscore) cursor, thinking it was pretty old and took a long time to boot I waited for it for another 30 Min, nothing. I removed the AC power cord (original that came with the model, I checked it on the internet) and tried to reboot, it went perfectly and booted into windows XP no problem, i even ran IntelBurn Test with RealTempGT to see if was doing OK and it did. So no problems running off of the battery.
I then tried plugging the AC cord in while still in Windows, it froze after a couple of seconds (about the time it took the power light on the charger to come on) and then froze again, removing the cord still left me with a frozen laptop. So no luck there. I tested the Voltage output with my multimeter and it was exactly what is should be, 19.5 V, I then plugged it in to the laptop (which I had disassembled) and tested the voltage that was comping in, also 19.5 V Exactly, so it's not the power port. If you need any more info please ask me.

Please reply asap.

Hi Hitman7987,
Welcome to the Community.
I understand your concern with regards to the computer.
As you say that the computer is freezing a lot when the adapter is connected to the computer. I would like you to try to update the BIOS on the computer and link to do it is: http://www.dell.com/support/drivers...
To update the BIOS on the computer adapter and battery needs to be connected to the computer
If this does not work, try to connect with a different adapter (if available). If the system is working fine, then the issue is related to adapter else could be connector on the motherboard.
If you have any questions further can reply back to us.

Thanks for your quick reply, I have tried to update the bios but it needs the AC cord plugged in, which makes the laptop freeze rendering it unable to update the bios, do you perhaps know of a way to force flash the bios?
Oh and another thing I saw while trying to charge the battery with the PC off, is that the battery light flashes Orange, Orange, Green and repeats them processes. If that is any help please respond ASAP.
Thanks,

Hi,
There is no other way to update the BIOS update on the computer as you would require ac adapter to be connected to the computer.
With regards to second concern that you have where it is flashing Orange, Orange, Green and repeats them processes it states that the issue can be with the battery not getting charged properly sending you the link for document where you can mention about it http://support.dell.com/support/edo...
