Battery discharge order

I'm running with two batteries: standard 6 or 9-cell, plus a battery in the ultrabay slim. The ultrabay slim battery discharges first, then the standard battery.

Is there a way to change the order, so the standard battery is used first?

There isn't a way to control the order.

Logically thinking there should be one, the ultrabay battery should be used when the main is empty, so it'll power the machine while the battery is changed.

You are so right!
Many a time, I have cursed the discharge sequence...My slim battery has about 120 discharge cycles through it and it is down to 60% rated capacity...it is only 9 months old!

i bought this thing, thinking it would be used when the primary battery is depleted.

Alas....not so.

I would be cool if someone could hack the BIOS on these T4x to alter the discharge order...

Oh God..I must be tired...my typing is atrocious!

Can't you replace that battery under warranty?
And incase they only replace the big batteries, you could get a 9cell one, of course, if you already don't have one.

Well, this is a bit wierd, the battery was already 1 year old when i got it back in March 04, it was manufactured in February 2003!
I thought nothing about that until I see that it was not holding it's charge as well I would have hoped.

IBM promises to take it back, but I keep forgetting to get it to them....Ahh well, Perhaps I will do it one of these days before the 1 year is up!
