combining R52 base with T42p screen?

[ilakast]

The closest I could get to any relevant post was the 14.1" T41/R51 Frankenpad (Intel GMA 900), SXGA+? so if this has been asked before let me know.

Having inherited a few thinkpads from edik I am now looking at possibilities to get the most out of them.

T42p (2373-HSG) has an issue that I cannot resolve as yet but apparently a working IPS screen. R52 (1846-AQG) has no screen at all but hopefully has a working motherboard (haven't tested it yet). Could the 64MB ATI Radeon X300 drive the T42p screen and are the pins compatible? I have all HMMs but no clue as to what I should be looking for

Yes...the R52 board can drive the UXGA screen no problem. You will, however, need the UXGA ribbon cable to stay with the screen, and I think there might be some difference between the T and R series cables (length, I think), so best bet might be to put the R52 motherboard in the T42p chassis.

Brilliant, thanks for your reply. Found my weekend project, will report back with any results

Just in case: the T43/R52 uses different CPU and RAM, that is NOT compatible with the T40/T41/T42/R50/R51.
And if your R52 has a 1394/Firewire port, there is no opening for it in the T4x base.
In a 15" T4x you could cut a small 'matching' hole with an Xacto knife or Dremel (between PCMCIA flap and fan exhaust).
Also, the fan from an R5x is higher/thicker than the T4x fan, so reuse the T4x fan (it will fit).

Thanks for the tips.

Unfortunately the project came to a halt, the R52 has a power on password. Following lenovo's steps wasn't succesful. I booted with an external monitor, did not try the T42p screen at all. I am not very confident that edik will know the password, so if I don't post again that's going to be the reason...

Not feasible to get the R52 booting in the near future, so would a R50e be able to drive that IPS screen instead?

The R50e only supports XGA.
