Yeah, it looks like I just have to buy a 4.5A power supply to replace
the 3.5A one, as the new 4460mAh battery requires a 4.5A charging
current.
I did try inserting the battery while the machine was not powered on,
and had the same result: the power supply would turn off after a few
seconds.
I'll let you know if it works with the new power supply!
Thanks agian for your help,
Chris.
