|"Just fix the floppy drive."|
Does it spin for at least a short time when you insert a floppy disk into it? It MUST spin.
If it doesn't, remove it, open it up, and see if it will spin after you have fiddled with it.
If it DOES spin.......
"Or maybe it just needs a good cleaning."
Try a standard floppy drive head cleaning diskette in it, without or with cleaning fluid on it's "disk" (e.g. isopropyl (rubbing) alcohol, or methyl (wood) alcohol, or ethyl (drinkable) alcohol).
There were five models (That I am aware of) in the T3100 series: The base T3100 (Which I shall discuss here), the T3100/20, the T3100e, The T3100e/40 and the T3100SX.
The base T3100, released in 1986, consisted of an 80286 CPU running at 8MHz, but could be slowed to 4.77MHz using a keyboard shortcut. It also had 640KB system memory, which could be upgraded to 2.6MB. It shipped with MS-DOS 3.2.
Storage included a standard 3.5" 720KB floppy diskette drive, and an internal 10MB hard disk drive. An optional external 5.25" floppy diskette drive could also be connected through the parallel/printer port. The T3100 also had a special optional "floppy link" cable, which allowed the T3100 to connect to and use the floppy drive on an IBM desktop system.
Although portable for the time, the T3100 is a beast in comparison to today's portability standards. It was 12.2" wide, 14.2" long and 3.1" thick, and it weighed a hefty 15 pounds, quite a burden to carry around. ....the T3100 was simply just a luggable computer. Except for the T3100SX, it had no internal battery, thus it required access to an AC outlet to operate.
Quick info about the other T3100 models:
• The T3100/20 was essentially the same as the base T3100, except it had a larger hard disk drive (20MB instead of 10MB).
• The T3100e had a 12MHz 80286 CPU, 1MB RAM and a 20MB hard disk drive.
• The T3100e/40 was the same as the T3100e, but with a larger 40MB hard disk drive.
• The T3100SX had a 16MHz i386SX CPU, 1MB RAM and a 40MB or 80MB hard disk drive, and also included an
internal rechargeable battery for true portability.
T3100 Bios Setup
To gain access to the T3100e BIOS, hold down the [Fn] key while it is booting up. After the memory check is finished, there will be two short beeps. Press [F1] to get into the BIOS.
That should work for your T3100/20 too !
