T43 whole lid swap?

[dcouzin]

I have two identical model T43's. One runs Win 10 as my main computer. The other runs Win XP (needed for a few old actions).
One T43 has an unreliable DC jack. The other T43 has a pretty bad display -- a reddish 53 nits rejected by my bank's optical TAN generator.
I haven't the heart for the teardown necessary for replacing the DC jack, so that T43 should be the Win XP one.
Swapping displays is also an unpleasant job. I remember the plastic prying, and uncertain taping, and fussy squeezing in of antenna wires.
Is it possible to swap the whole lids of the two T43's?

Thanks.

If both are the same size (14.1" or 15"), then yes, no problem, BUT...
14.1" Intel only takes XGA.
14.1" ATI takes both XGA and SXGA+.
15" Intel only takes XGA and SXGA+.
15" ATI takes XGA, SXGA+ and UXGA.

PCDR5 says they're not quite identical. The 2668Y4G is 9½ months later than the 2668WMZ. Their one difference seems to be in their ATI X300 graphics cards, the later having 128 MB memory vs. 64 MB. They have the same 1400x1050 TFT panels.

I trust there is compatibility between the two lids. I'm asking about the amount and kind of work involved in a whole lid swap.

P.S. There are not ATI Catalyst drivers for Win 10, which treats the X300 as a "basic display adapter", so direct color control is lost. (One could build funny ICC profiles.) The T43 isn't 100% itself with Win 10, but it's a decent computer.

Pretty much the same machine, apart from the CPU.

You need to remove battery, hard/media drives, keyboard, both lower bezels, unhook the antennae and unscrew the lid. It shouldn't take long and HMM is your friend.

I *believe* that you can force Vista driver - the last one to be developed for X300/X600/V3200 - to run under W10. Just don't ask me how, since I don't run W10 and I never will.

Good luck.

George, mine is 2668-Y4G, not 2669-Y4G. I think all 2668's have the 2.0 GHz CPU.

Great thanks for the Hardware Maintenance Manual reminder. Swapping whole lids will be much easier than swapping LCD panels.
But oh, to have some control over color.

The only difference between 2668 and 2669 was warranty entitlement when new. And no, not all of 2668 units have 2.0 CPUs.

Well, can't you load the profile from an older OS? Once again, I've played with W10 for one day and decided not to touch it with a thirty-foot-pole ever again, so I might be way off base here...

I stand corrected. However my two T43's, 2668-Y4G and 2668-WMZ, do both have 2.0 GHz CPU's.

So I downloaded 1yd302ww.exe from Lenovo and it ran. I found the setup.exe file it put somewhere in c:\drivers\win\video and it ran too. Catalyst Control Center sort of installed. Device manager now recognized that there was an ATI X300. Win 10's visual color calibration routine could now do something: gamma adjustment. But the CCC itself was crippled, no color adjustments possible, and it flashed the message:

The Catalyst Control Center is not supported by the driver version of your enabled graphics adapter. Please update your ATI graphics driver, or enable your ATI adapter using the Displays Manage.

Color adjustment, rather than profile choice, might be one thing the T43 forfeits under Win 10. There is also no Lenovo Power Manager with battery info, and Win 10's own battery report doesn't work. But on the whole, the T43 works with Win 10. It's as peppy as with Win XP. The T43's 2GB memory limitation isn't fatal. And use of Classic Shell makes Win 10 not gruesome.

I've got no wisdom to offer here...

There's a sticky on getting Power Manager to work in W10. No first-hand experience on my part, though.

Oh I know it works. I run W7 on the T43pSF in my sig, and it does OK. It's just that I maintain no interest in anything that MS has dished out after W7. But that's me.
