It really is an easy mod to upgrade the screen, just don't go try and pair up the intel chipset based thinkpad with a UXGA screen.

Thats exactly what I am trying to do.

mmmm, I would not recommend you proceed, but it would be interesting to see if someone else has better success

I'm gonna ask you for a little favor..

Can you please post the following:

- Your model number (You said 1871-XXX something..?)
- Laptop's configuration 14/15" T43 - CPU - Video Card - Mem - HDD - etc. (Stuff thats not directly available through the MODEL number lookup in Tabook)
- The FRU for the LCD Assembly you bought

Last but not the least an LCD parts look up.

http://www.cpuid.com/pcwizard.php

CLICK: File > Save As.. (Brings up Dialog box)
SELECT FOLLOWING OPTIONS IN DIALOG BOX:
Range: (o) Selected Category: Hardware
Format: Format TXT

Also do the same for DISPLAY.

I'd really appreciate it.

Also, I wanted to see what you had on your machine in terms of: FRU / Model numbers for - LCD, the Inverter, the Cable Assembly etc, the Video Card. - The ones that WORKED and the ones that DID NOT work. Whatever you can remember from your experiments.

Hi,

Will help as much as I can, but note I am running linux, not windows, so I cannot run the pcwizard software. During my attempted upgrade, I did install windows on a partition, to allow me to run the pc wizard program upon request from those who tried to help, but I have dumped the install by now as I required the hard drive space.

As far as I know, there is no easy way to get the FRU part number for the screen, appart from taking it apart - which I am not going to do, as I don't want to run the risk of breaking it now that I have it working. If anyone who reads this know of another way, please do tell.

You can consider asking Dimitri (whom I had bought both the screens from) if he could help with that information. He does hang about on this forum, and he does have an ebay shop (check previous posts) He may be willing to help. If, by chance he knows, but does not want to devulge info about a sale made to me due to privacy reasons, point him to this post, as I don't mind him giving you such details about my purchases with him.

If you need any further info, please do ask.

It would actually be nice if there was some way to boot windows from a cd, to allow running the pcwizard software, but I don't know if that is possible.

Regards
Lucas

Did I not see someone reporting that they had run PC Wiz & other such apps under a Windows PE environment ... WinPE, Barts PE Cd etc?

Yes, your'e right. BartPE has a way to boot from USB stick

I am trying to make one, and will get back to you with the rest of the info once done.

Having a bit of a problem getting bartpe setup with a working pcwizard on it. Get the boot cd made (abandoned the flash drive one, as I found my ultra bay dvd writer - have not used it in months) but pcwizard just hangs when starting up.

Anyone know where I can download an ISO image with a working boot, with pc wizeard on it ? Burnt 8 cd's already, still not got it.....

Upgrade my screen to uxga today.

As mentioned, very easy to do, easiest mod i had done to date, took about 15 minutes.

I am now getting 1600x1200 res, but ran into an oddity. My screen runs off to the right of the physical display, by exactly a quarter in size of the whole display.

Any ideas ? Can't get to my expanded windows scroll bars, close buttons etc.

I do not even get the 1600x1200. I am getting a stretched blurry version of 1024x768. How did you make yours happen originally?

Darn. Sorry, out of ideas for now...hmm.

Yeah, and I would guess that swapping inverters would probably not have done any good. The inverter is strictly used to power the display.

Think, think, think...

@ Nathan - Are you sure? Then why the big deal about INVERTERS when anyone is doing a screen mod?

Note the Working desktop.....I think that is the part of my desktop that actually fits to the physical display and is visible to me.

@dedmeet - Marked in bold - What did you do exactly? I want to try the same.

I still have my fears that Lenovo and IBM are total pedantic about keeping everything stock, so that one could not buy one of the cheaper T43s and basically turn it into a T43p (w/o the GPU performance).
That might also partly explain why there is an XGA and a SXGA+/UXGA LCD cable available, and two different BIOS firmware downloads available.
They have all the power to code it in firmware that display resolutions of the LCD is 1024x768.

I still have hope that the SXGA+ screen from the T43 works as it should, since it came from a T43 (and not T42)

Would they go that far to restrict things in the BIOS?

Boy, I'll say! Let us all know who the seller is so that those of us here who might need some ThinkPad parts can reward him with some extra business.

For what it's worth, I also hope the SXGA+ panel works out for you, and I think there is some reason to hope that it will, given that there are, as others have pointed out, R-series models with the SXGA+ panel paired with Intel graphics. But that doesn't mean anything, really.

Keep us posted.

-- Nathan

@ Nathan - Which R series are those? I went through the former Tabooks and when I searched for GMA 900 the only models it would show having that card were the XGA ones.

dedmeet wrote:Hi

Well, new screen (SXGA+) connected, and practically worked out the box.

I had to patch the video bios to allow the 1400x1050 resolution in xorg, done with 915resolution program.

There is a new xorg driver (called the modesetting intel driver) that allows xorg modes to be specified, with out having to use 915resoluton, but I could not get my external screen working in dual head using it.

915resolution works 100%.

Many thanks to all who had tried to help with this upgrade.

@dedmeet - Elaborate on that PATCH please? Did you modify the BIOS or just some Video settings in Linux?

Did the SXGA+ work under windows as SXGA+?

Did you try a similar PATCH / HACK with the UXGA? or you tried it only when the SXGA+ came along?

Out of curiosity, had you tried to use 915resolution with the UXGA screen when you had it?

Did the BIOS screen look fine with the new SXGA+ screen out-of-the-box, so to speak?)

-- Nathan
Yes I did, but it had no effect The bios actually had the UXGA resolution listed, so there would have been no need to do the patch, if the screen had displayed correctly.

I even tried replacing every bios mode with the 1600x1200, did not work. Using the modesetting xorg drivers I did mamage to get 1600x1200, but it was still off-center, to the right.

Figure the eventual assesment made was correct, UXGA with the intel chipset just was not possible, possibly due to a firmware bug, or intentionally done by IBM

The bios screen etc all look fine, perfectly centered on the SXGA+

I am very very happy now

At least my 'experiment' had help add to the collective knowledge base, and hopefully someone who was thinking about the same upgrade will be spared the hassle, and cost involved. I was lucky in the fact that the money involved was not my own, but from my company.

I'd like to figure this out and try it out. Could I get some guidance?

Did nothing, that was the default mode, I got with the UXGA. You can try and change your bios settings, but that only shifted my screen to the right, but still had 1600x1200. When checking the available bios modes using 915resolution, that mode was the last mode listed, so it was the default.

Could it be because you are working with 14". Mine is 15"

crashnburn wrote: @dedmeet - Marked in bold - What did you do exactly? I want to try the same.

Been a while, I recall that for some reason i had about 3-4 monitors/panels listed under control panel->system->devicemanager->monitors

They ranged from 'Default monitor' to VGA 1024x768 lcd (or something like that). I removed them all, and then made sure to just have 'default monitor' which was plug and play listed. This took quite a bit of trial and error, as everytime xp reooted, it just put them back. There was also one for TV listed I think. Think I used 'safe mode' to remove them.

crashnburn wrote: Would they go that far to restrict things in the BIOS?

It is a high possibility. We would never know, unless someone actually asks them. Consider that it is not benificial (financially) for IBM to have us upgrade like this. It woudl be best for them that we go out and buy a whole new laptop. Their main concern is still just making a profit.

915Resolution (and 815Resolution) are userspace BIOS level patch programs that allow you to 'patch' the display bios and list new display modes that the built in bios does not support.

You cannot append new modes, you just replace a current mode with the new one. for example I replaced the 800x600 mode with the SXGA+ mode (1400x1200). Now in my xorg config files I can specify that mode. Without the patch xorg will complain that the bios does not support the mode.
Google for 815Resolution, been around longer, so you will get more hits, then you can read how it works.

The patch needs to be applied after every reboot, thus it is part of my startup sequence.

Yes I tried doing it with the UXGA screen. No luck at all.
Yes windows worked on the SXGA. Don't recall if I had to patch the bios as well, but if I did I would have used a program called PowerStrip, which woud allow you to patch the video bios in windows. PowerStrip is the only proggy I know that works well, as I use it for psone lcd screen mods I have done.

crashnburn wrote: I'd like to figure this out and try it out. Could I get some guidance?

Personally, I would suggest you go for the SXGA+. I tried for many days, many hours, with a lot of help from the other members. We could just not figure it out. I still believe it is not possible, but that is just my opinion.

If you do get it right, I will be the first one in que to get a new UXGA screen and try again.

Sorry, should have documented some of the stuff I tried, but I did so many things, some in despiration, some totally illogical, nothing worked, and as the ideas/help dried out I just gave up and went SXGA+.

Understandably though it was amazing in the kind of information it could read and cycle towards the LCD.

I doubt it. Its working 1600x1200 (Also did one more thing -

Display Properties > Graphics Options > Panel Fit > Maintain Aspect Ratio.

This creates a BLACK BAR on the left of the screen - It being equal to the amount of screen that gets shifted to the right.

Sorry, no
You don't actually have to install linux to try it. You can run linux off a 'LIVE-CD', meaning you can boot from a cd/dvd that holds a complet linux distro, thus keeping your windows on the hard drive intact. The trick would be to find a linux live-cd distro that contains 915resolution. check out www.distrowatch.org - their distro search option may help, or just try going at it with google.

Powerstrip comes into action once you logon to windows, it is part of your startup programs. So even if you do get it to fix the issue, you would only get the correct display once you login. I am unsure if it canrun pre-login, but it is entirely possible. Boot (and BIOS) would still be wrong as powerstrip cannot work that low-level (before windows) I am not a guru on powerstrip, and have not used it in a while, so I can be wrong.

Yes, I think that is the main issue. In my case the graphics chipset thought the panel was a wide screen, thus it tries to display widescreen. It may sound simple, but the trick would be to fool the chipset to read the panel as UXGA not WUXGA. How this could be done I could not find.

I also got that, with the black bar to the left. Basically what happens here is that the 'stretch' is gone, and the chipset tries to center the image on where it thinks the center of your physical screen is (well, that is what was deduced). I can only figure that if you really had a wide screen the right hand side would also have a black bar, same in size to the left one, thus a 'centerd' image. you just can't see it.

There was someone (check the previous posts i this thread) who aparantly did get it right to 'shift' his off-center screen to the left, thus making it display correct, but I think the cause was not the same, but the end result was what you get. This did give me hope, but his post did not reveal how he did it, and a private message asking him how he did it gave no response.

Which one was that? I cant seem to identify the post and what he did.

I am aware of Live CDs but I havent touched linux in ages. So I'll try to look for it. Are there any forums where I could ask people which LiveCDs have it?

I mean, this is far from a standard question, just like they can't answer how to DIY outfit a T40 with a WWAN antenna, although it might be possible.

You might want to write to DB2DUDE considering his last post could sound like he has tried playing around a lot with this,

I was aware I would void the warranty. To get rid os the 1024x768, well, it seemed worth it.

I contacted DB2DUDE via pm. Hope he is still around, as the issue he described sounds the same. Old post (2005), hope he is still around.

Gives me some hope that the issue is correctable.

Have a look at this thread, http://forum.thinkpads.com/viewtopic.ph ... pgrade+lcd, second last message. Not exactly the same issue, but in my opinion close. What he did was fool the monitor EDID to bios comunication to set the correct lcd type.

In my view that is what we get with the UXGA EDID says it is WUXGA. I could not get it right. He did not respond to my questions.

Check out https://www.scientificlinux.org/news/livecd-50 The first listed program on this live-cd is 915Resolution. There are many more I just googled with term 'linux live-cd 915resolution'
