My t42p LCD went dead yesterday. they are sending someone over to fix it tomorrow. Its all well and good, but im afraid that this new screen they're going to give me is gonna have dead pixels. Does anyone know IBM's policy on dead pixels? I guess if worse comes to worse i could pitch a baseball through the screen and claim it as an "accident" but i just dont think i have the heart

Hardware Maintenance Manual, p. 65:

http://www-3.ibm.com/pc/support/site.ws ... MIGR-46464

"The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. The LCD should be replaced if the number of missing, discolored, or lighted dots in any background is: * XGA: 8 or more bright dots, 8 or more dark dots, or a total of 9 or more bright and dark dots. * SXGA+: 11 or more bright dots, 13 or more dark dots, or a total of 16 or more bright and dark dots. * UXGA: 11 or more bright dots, 16 or more dark dots, or a total of 16 or more bright and dark dots. Note: A bright dot means a pixel is always on (white or color.) A dark dot means a pixel is always off (black color.)"

Yes, sure you can, just as you like, it's your personal property. But they won't repair it for you unless you pay them. Accidents are not covered by the warranty, of course. Do you really think the people at IBM are nuts?

maybe he has thinkpad protection

i mean he has onsite service already so i doubt he has the standard warranty
lol

thanks for you reply. I guess i forgot to mention i have accidental protection coverage on my machine.

Why not wait and see if (1) the LCD actually needs replacing (the problem could be with something else, e.g. a loose cable) and (2) the new LCD has any dead pixels (it may not.)

Ethical issues aside, why would you suppose that the 3rd LCD will have any fewer or less objectionable defects than the 2nd?

I once read a study which says 30% of notebook LCDs manufactured are prone to have atleast 1 dead pixel from factory itself. It IS possible to manufacture deal-pixel-free LCD, but the total LCD production cost grow up a lot and so the TP cost.

I have a dead pixel at the bottom. I worried first and asked my dealer who has a good relationship with IBM. He said he can manage to send the TP back to IBM, but there is no garantee that the new LCD arrives after replacement has no deal pixels. It may even have more than one or 4 or 5 in worst case, where you can't do anything.

The waiting time/official procedure until you get a replacement for any accident/damage is a headache.

I would keep it, though there is one or two dead pixels. Sorry, your opinion may vary.

one way to get over the problem, it seems to me, is to check thinkpads for dead pixels and then to sell them at lesser prices for increasing number of dead pixels.

How do they get away from this problem on desktop LCSs, or do they? We have 25+ desktop LCSs in the office and not a single one has a dead pixel that I can find...

desktop LCDs are not excluded from dead pixels according to above document, but I agree with you (mattfromomaha) in my opinion. All in my dept. have mostly good desktop LCD with much lesser dead pixels.

In my guess, one difference is that backlight is good in desktop LCDs, besides the build quality (no need to think of LCD weight, etc.). This may make a difference.

As you see from the above link tomshardware, IBM is not clear which ISO specs (which class!) that they follow or they may not follow a specific spec, but implement their own(legally or illegally I dont know) spec.

well, the guy came to fix the LCD but he made everything worse. IBM sent the guy the wrong LCD (the XGA model). He connected that LCD not knowing its the wrong one, and then computer would shut down two seconds after turning on. After noticing that the LCD is the wrong one, he connected my old LCD back, hoping that it would atleast startup again. No such luck. The motherboard is zapped. Now hes gonna come back this friday to install a whole new board into the computer. Word to the wise: dont get on site service! the guy who was fixing my computer was using a swiss army knife as his primary tool. WTF is up with that

Was this guy really from IBM or from some outsourced repair company?

In either case, something is wrong with the service provider. Report your experience to IBM management. The words you've posted above are sufficient (although I'd lose/reword the last sentence

)

After alot of hassle with IBM, my computer is now fixed, but the guy who installed the board didnt update my serial number and the machine model-type on the motherboard. I made IBM cancel my on-site service, so now they are telling me to that i have to ship my computer out for them to update the serial number. This is bull, i cant be without a computer for another 2 weeks, let alone the 3 weeks i had to wait to get the motherboard changed. I was reading the hardware maintenace manual for my machine, and it mentions the "Hardware Maintenace Diskette" version 1.71 that can do the job. Do you guys know where i can get that?
