Hi guys,
Bit of a strange one here.
I will soon be getting a Compaq M300 with the MEU but I have been told
the battery is on it's last legs. I have found a source for a battery
that sits in the Multi-bay of the MEU (docking bay) but I wondered if
such a battery will still power the laptop if the laptop battery itself
is dead or not even in place.
Obviously it will only work with the laptop connected to the MEU (I
ain't that fick, lol)
My thinking being that maybe the drive bay battery runs the laptop
THROUGH the laptops own battery.
Any clues?
Cheers,
Steve

Dunno about your Compaq, but my old Thinkpad T30 had a drive bay
battery and it would power the laptop while the main battery was
removed.

The right bay has 2 connectors: a connector for the battery and another
for the cd/dvd.
With a CD/DVD in there it uses ONE connector, the battery uses another.

It will work fine. In fact, the M300 does not run off both batteries at
once anyway; it drains one first, then the other. I think it pulls from
the bay battery first, then switches to the main battery once the bay
runs out of juice.

However the M300 is significantly ugly and heavy with the MEU attached.
There are plenty of sources for third-party normal batteries; grab one!

(The MEU battery does, however, last longer).

Thanks for the helpfull tips, guys.
I'll let you know for sure when all the parts get her and I've tried
them out.
