Re: [Thinkpad] A21e to A21p upgrade project - works, with a small snag - advice needed

If you look at the mobo's for sale on Ebay, they do seem to be specific as
to which LCD they work with. Probably incompatible with your unit.
It is also possible that the REASON that Mobo was pulled is that the video
card is bad!!

snag - advice needed

> I am in the process of upgrading an A21e (celeron 700) to an A21P with a
new system board (12P3291) and a micro-PGA PIII 850. I am using the A21e's
existing 1024x768 screen. I work on Thinkpads from time to time, but mostly
replacing parts on a one-for-one basis, so this one has me stumped.

speed, cooling seems adequate, etc.) - EXCEPT that the LCD only displays a
compressed image in the lower left third of the screen, rather than a full
screen image. This is not a driver issue, as it occurs before on POST right
after power-on before any drivers are even loaded. It is also not a dead
LCD, as I just watched it work with the other motherboard and the same sub
card.

> Again, I am using the 1024X768 XGA 15" screen from the A21e. I have
noticed that there are no A21ps with this resolution, but shouldn't The Rage
Mobility 128 be able to adjust for that? I am using the sub card from the
A21e, which I figured would work since the screen is the same (am I wrong on
that, and if so, would an A21P sub card which is presumably designed to
operate a 1600X1200 screen work with the XGA screen?

the A21P board, EVERYTHING else works, and I would really like to keep the
better video card if possible. Any ideas? Thanks in advance.
