| IBM ThinkPad A30p display defects Once again, my ThinkPad A30p (model 2653-65U) has developed the infamous display problem that has plagued many A30p owners; flashing blue lines, unreadable, garbled text when the machine is turned-on. The display corruption (seemingly) stops after WinXP loads the display driver (the Windows GUI looks OK), BUT full-motion video (overlays, et al) is severely distorted (flashing horizontal lines), AND instead of 32MB video memory (onboard), only 16MB video ram is detected by the driver, the other 16MB of VRAM is missing! This can be verified in WinXP by bringing up the Display Properties (right-click on desktop), Settings, Advanced, Adapter tab; the detected Memory Size *should = 32MB*, but it shows only 16MB, where did the other 16MB go??? obviously, there is a hardware problem. details - On the A30p mainboard, there are 2x16MB Samsung memory modules located near the ATi M6 GPU (Graphics Processor Unit), which as we know is NOT heat-sinked (big mistake) and gets very hot (because it is located underneath the CPU's heatsink); this design flaw leads me to conclude that heat and/or mechanical stress has caused the GPU to form a cold solder joint, which is BGA-mounted (ball grid array) to the mainboard, or perhaps micro-cracks formed in the mainboard itself. Whatever the actual source of the problem, it results in an electo-mechanical failure; if the A30p chassis is moved or flexed slightly (during POST), the distortion pattern on the screen (blue lines, garbled text, etc) also changes and sometimes the video corruption will temporarily stop. In my case, this is the second time it's happened, the motherboard in my A30p was already replaced once, for the exact same problem (blue lines, garbled text during POST, missing 16MB VRAM). I suspect that the display corruption problem stems from moving the ThinkPad when it's still warm. That is, after the A30p has been in operation for a while, the mainboard and GPU heat-up considerably, then, if the machine is packed-up and in-transit (in your backpack, laptop bag), expansion/contraction of the internal components (GPU, mainboard, et al) and mechanical stress (from normal usage) on the delicate chassis causes electrical connection problems to develop; certain components (GPU or VRAM) become disconnected or the mainboard itself develops micro-cracks (broken circuit traces). IMO, there are design/manufacturing defects with the ThinkPad A30 series, but will IBM will acknowledge this? Unfortunately for their customers, probably not. Incidentally, I've also had the LCD display panel replaced in my machine twice, because the backlighting dies; there's a problem with the fluorescent tubes, they prematurely fail. Has your backlighting gone dim, acquired a pinkish hue, particularly during a cold start? That means they're gonna die soon. The backlighting in my A30p died not long after I bought the machine. The backlighting issue is unrelated to the overheating GPU (display corruption) issue, however. Whatever the sources of these well-known display issues, the simple facts are: A30p ThinkPads are prone to LCD and GPU/VRAM (heat-related) failures and the chassis is much too delicate for portable use. I firmly believe that IBM should make amends and offer to extend the warranty on these defective A30s, the machine is prone to serious display problems, making it unreliable and costly to own (repair costs, downtime, frustration, etc). It's shameful that IBM won't acknowledge and take responsibilty for what is obviously a manufacturing and/or design defect. My otherwise great experience with the A30p has been tainted by its persistent display problems. The reason I bought the A30p was because of its high-quality UXGA display, ironically, it's the one thing that's been an unending source of frustration and expense. And this machine was not cheap either, with a base price of several thousand dollars (cdn), plus hard drive and memory upgrades, etc, it set me back almost $5,000! I expected to get at least 5 years of trouble-free operation out of it, but it was less than a year before all the problems began. Anyone got ideas??? Can we, as a group, petition someone at IBM to replace our (defective) motherboards, free of charge... hell, I'll even put the board in myself if necessary, I've already replaced the LCD panel myself (the second time it went dead). The A30p has a beautiful display - when it works that is - but the machine is too delicate and sensitive to heat. Someone at IBM knows this, but they're not talking... or listening either. If someone at IBM/Lenovo is reading this, please FIX what is YOUR mistake, and do right by your customers. Replace our *defective* motherboards at no charge or at least offer us an upgrade to the A31 series perhaps, for a nominal fee, if any. Restore our faith in IBM... and what WAS a good brand of portable computers. btw, my A30p is the third ThinkPad I've owned over the years... the other two are still working great, even though they are older models. too bad the same can't be said for this A30p hunk of junk. -- francis techcafe******.com other issues with the ThinkPad A30p include well-known problems with the IEEE1394 bus controller and Philips S-video decoder (PHILDECN.sys). Essentially, the firewire bus is unreliable (resets itself intermittently, causing data loss) and the PHILDECN.SYS driver causes intermittent blue screens in XP). i've had to disable the Philips WDM Video Decoder via the Windows device manager just so the machine remains stable. Thankfully, I don't need to use the S-Video ports, and I was forced to buy a PCMCIA firewire card, but shame on IBM for not dealing with these obvious defects. |

I agree that it's likely a bad joint under the GPU, or possibly a broken via. However, if the machine has outlasted its warranty period (which it has), then IBM's obligation to you is at an end. If it was my machine, I'd try heating the area under the GPU with a butane torch to re-melt all the balls (practice on something disposable first!). Note that the bottom surface of a BGA chip is made out of FR4, or if not, another material specifically chosen to have the same coefficient of thermal expansion as FR4. This is intended to prevent joint stresses caused by the chip expanding faster or slower than the board to which it's mounted. > Incidentally, I've also had the LCD display panel replaced in my > machine twice, because the backlighting dies; there's a problem with > the fluorescent tubes, they prematurely fail. Has your backlighting I'm surprised you haven't encountered the other common problem with the A30 series, which is the infamous "Fan error" message on powerup. I'm selling a bunch of A30 series parts including a fan-error mainboard (but good video :) and an LCD/inverter - search for eBay user ID larwe74. I think the whole set of lots is currently under $10 right now, including the LCD :) > set me back almost $5,000!

Buying a piece of consumer electronics is a gamble. The manufacturer gambles that the machine will last for the warranted lifespan; they gamble very carefully and analyze the statistics to make sure they won't have to pay out. Consumers gamble very recklessly that their purchase will last {2x, 5x, 10x} the nominal service life, with little more than faith and hope to support their wager. |

Wrong again if they understand their legal rights. IBM certainly does and they will get off their lard arses if you make it clear that you understand your legal rights. |

I've owned 3 thinkpad models over the years, the A30p is the only one that has been problematic for me, so IBM could at least show some good faith too. > Note that the bottom surface of a BGA chip is made out of FR4, or if > not, another material specifically chosen to have the same coefficient > of thermal expansion as FR4.

You have > rights quite separate from the stated warranty. Ah, Speedy - unchanged in ten? fifteen? years from BBS_USER. Seems most people I remember from Fidonet wound up in the alt.* hierarchy. Coincidence? I think not. A claim of unmerchantability would not stand up in this case. And historically has not. In some very rare instances, mostly involving a defective component used in a huge number of machines (e.g. Toshiba's floppy drive controller settlement), class action has won the class members the equivalent of a $5 McDonald's voucher. |

Once you pull off the heatsink + fan, you should see one transfer pad on top of the CPU, one on top of the GPU, and some kind of rubbery mechanical buffer around the LCD connector, as you described. Hmm. Maybe the GPU pad was added in later production, or something. > > Note that the bottom surface of a BGA chip is made out of FR4, or if > > not, another material specifically chosen to have the same coefficient > > care to elucidate??? What else is there to say? The PCB and the bottom of the BGA are made of the same material. They expand at the same rate. > > I'm surprised you haven't encountered the other common problem with the > > A30 series, which is the infamous "Fan error" message on powerup. > > if it was a BIOS related issue, i've kept my ThinkPad up-to-date, so > that might explain why i haven't encountered the 'fan error' message... No, it seems to be caused by one of three things: a low CMOS battery (yes, I know it makes no sense), a bad fan (fair enough), or - worst - a failure of the tach circuitry on the motherboard. |

I've had the same problem with A31p and A30p units, and also with a T23. I still love the machines, but the GPU/heat problem seems to eventually cause them all to fail. The lack of "consumer replaceable parts" for this problem is a serious issue. -Chris |

Class action suits are an entirely separate issue to rubbing the manufacturer's nose in basic consumer law. Your claim at the top is just plain wrong. |
