The T41p was bought because my own T41p, bought from the IBM SPP used PC site, went dim/pink (presumably the CCFL). The T42 was hard to explain except it was promised to boot to BIOS and I wasn't sure what the T41p would do, so I thought one way or the other I could Frankenstein up something.
My own T41p I had previously shipped off to an outfit in MI called Business Services, at
http://www.bztechservices.com/ibmlaptoprepair.htm
not wishing to be bothered (this was some time ago).
They replaced the backlight but said it promptly fried and wanted over $100 for something I think they described as the video relay chip - or I could send them another mobo which they would presumably scavenge. I asked them what part number? They gave me what I was not sure was the right answer (though perhaps it was a common part) and at length I asked for it back, and they returned it. No charge, I give them that.
Happily the display still displays, but very faintly, as if the backlight were quite shot. Just as I sent it to them (it had been limping along with the screen getting brighter after some warmup time, but finally conked).
I mentioned this on another thread and was advised too look out for squalls if these meatheads had fried my mobo (as I say apparently not). And that if my mobo fried backlights, nobody will be very interested in it at e.g. The Board Room.
Well...the mobo is not fried. The backlight is not on. (The video still displays, faintly.) My understanding of the problem is not complete.
But what is positive is that I have a pretty clean parts/repair T41p from eBay, bless the nice people at scottsales, and I took the HDD and 9-cell and optional RAM from my machine and put it in the 'new' T41p.
It worked - a few BSODs, a few hiccups digesting the last gen 802.11b card (I had upgraded my T41p to an Atheros abg card trying to avoid the 1802 (?) error I learned of here many moons ago), but it seems to boot and run OK.
- The screen is bright and has no bad pixels at first glance but there are a couple of wear marks - which are not at all bad, really only one of any note, but my old screen was cherry.
The fan on the new machine makes a little noise which I simply don't recall or note in the other.
My abg card and 1GB SODIMM are still inside the original machine.
And my IBM SPP T41p was mfgr date 05/01 compared to the eBay T41p's date of 04/01 - so that GPU problem or any other crisis is theoretically a year farther down the road with the SPP piece than the new eBay piece.
Do I bother trying the CCFL again, on my own this time? Should I try the inverter first? Should I delve into this "video relay circuit" issue which bztech said fried the first backlight? None of the above?
Also: would need a new HDD not only for this but for the T42. Can't readily find an IDE HDD bigger than a 250, which is not too shabby but of course is more $ than a SATA. Well, can do. A 30-40-60-80GB would be fine if anyone has lying around...
but as an alternative, how about I get one of the first-gen SATA 2nd HDD UBay Slim caddies, which ThinkWiki says is intended for the T6x+ but has a bit of plastic which I can somehow get off and fit into a T4x, and use that as a boot drive? Is it such a huge ronking performance bite on the PATA-SATA bridge that (even assuming I can in general live without the dvd-cdrw) I will be sorry? Is there a SATA-IDE pin adapter which would fit inline in the prime HDD bay? (Surely not?)
Other than that, quite happy with the ebay T41p. Both T41s are the 2374-GGU, by the way. Oh, and the DC jack on the eBay T41p might be a leeetle wiggly.
Now as to the ebay T42...
which is a 2379-R6U...
it is a 15" XGA (1024x768) which is no great shakes. It seems clean, which I suppose is all I ask, but I can only boot to BIOS because of what appears to be a CMOS, i.e. battery error (date always = 1998). The HMM says 14.1" and 15" models have a different SKU.
Also googling on a T42 CMOS battery turns up a part which says it obsoletes many other old SKUs.
What should I buy? (Am I wrong that this is the problem? Should I buy several - if the same part can be used - and swap all 3 of the CMOS batteries as long as I have them open?)
Then again, the plastics are not clean. The top lid has a crack on the right side, no biggie but I notice, esp. as it mars the fit of the top lid and the bezel together along the edge. Also the top of the lid is a bit scratched up.
And the plastic grille over the fan exhaust/heat exchanger is somewhat bashed up. I see no functional impact however.
This T42 has 1GB RAM (I think 512MB was standard), and a b/g card which is good enough. No HDD no caddy no drive cover no adapter, and apparently no good CMOS battery. (BTW it and the T41p both have the 6-cell battery - one is OK condition one is red, a little under half strength, haven't tried conditioning it yet.)
So for another $20-30-40 in parts , I guess I can get it online. More for a new LCD (what are options?) if I went down that road. Again, maybe a SATA HDD in a UBay caddy?
In sum: What would anyone do with these machines? Who would want them? What should I buy? What should I sell? All three appear fundamentally sound (except maybe my SPP T41p if it fried backlights). If I chose to keep them or value their use, I would think to max out all their RAM, but maybe that is a waste of time if I am to sell or part them.
Oh, they all have XPP COAs. Can I use the same recovery disk set on all? Or, having one good HDD with a recovery partition, can I use this to clone to new IDE or SATA HDDs of the others?
Umm...Also: on long boot, the T42 BIOS says that it is US Government property and should not be resold. ?!?!?!? Of course that was so many years ago. But should I call the GSA or the FBI or somebody? Will they care? Will they arrest me and/or my eBay seller? Will they offer me a new Lenovo in trade, haha?
Anyone with personal interest please PM me. I would be glad to sell any or all of them at this point, Dad can have that T400 or I can move into that one and give him my T61.
