Yeah, the T4800 I have suffered the same fate (resume batter leak), and it was clear the previous (not the seller) found out and removed it. There wasn't much damage, would need a serious cleaning. Just powder everywhere.
But I do agree, the proper glass covering just makes it look different compared to plastic covered. It's also much easier to clean.
But yeah the 4400's have a proper socket. Shame they don't have the expansion abilities (or even integrated sound) because with a x5+voltage shim and a recelled, higher capacity battery they would have been killer portable DOS gaming machines.
Today's retro activity: I am true to my word. I went ahead and stuffed the 63MHz Overdrive in my T4400C.
Sadly I didn't take a picture of the underside to show the rigging, but it was essentially this: Re: This 486, can mount the pentium overdrive?
I selected the Overdrive not for performance, but for the full Pentium compatibility. In this case the fan was removed so it would fit in there (not much space) as well as to disable the multiplier as it isn't being supplied through enough power pins. I didn't want to risk it with this portable (by pulling too much amps through the pins supplying power). Not to mention the lack of airflow in this laptop.
Running at 25MHz isn't stellar. It's still a wee slow, but there is a noticeable performance increase in certain areas. I just need more ram.
