Mitac 6133

Mitac 6133

The Mitac 6133 was a Celeron CPU (PIII core based) laptop that shared case design with the 5033 and 6033. Fastest CPU that I've seen installed was a 550 MHZ, but faster CPU's may also work.

The 6133 used the same floppy drive and CD-ROM drives as the earlier 5033 and 6033. Keyboard design appears to be the same size, but keys have been moved around somewhat. I do believe that they all do swap with each other if one is in great need. The plastics did evolve during the evolution and so not all plastics exchange with the earlier models. Most LCD lids are the same except for location of LCD mounting holes and LED locations.

The motherboard came in three sub-revisions per Mitac, but the BIOS appears to have been the same for all three revisions. Current newest BIOS is R1.17 I've not been able to flash any of my 6133's to this newest BIOS since the MiFlash.exe program informs me that the BIOS chip in my 6133's is not a supported type. (???) Besides and Mitac laptop BIOS update is a bad thing, there's a 99.9% failure chance with no hope of recovery. Don't do it!!!!!!

I have installed up to 12GB HDD's. Larger will most likely work, but untried. Memory is limited to onboard plus one SDRAM slot. I've installed 256MB FULLY compatible RAM modules (not the cheaper and much more common sticks!) and with 256+onboard you can run at quite decent speeds with newer OS. Fully compatible modules cost more and most have 16 chips (or more), if you use a 256 cheapie module - it will report as 128 MB. So don't buy incorrect memory.

Mitac support is gone and limited parts show up on the internet and are rare at this time.

CMOS battery is a 2032 type with long pigtail leads.
