OK LETS ALL JUST CHILL OUT HERE. FACT: Pres is acting in good faith as is everyone else who posts to this list. We all want to do our best to spread what we know and our experiences to others such that they may avoid the pitfalls we face. Pres is to be commended on not shrugging his shoulders and saying "Fine, destroy your libbys then" much earlier, the rest of us are to be commended for accepting what he says without degenerating into a flame war. As long as the debate remains cool and accusation free we've got good lively debate and lively debate expands our knowledge. Its started to degenerate a little into accusations of misinformation which I think is starting to get too far to be healthy for a list such as this. FACT: Pres has a point - it is quite easy to damage the motherboard. Given that laptop motherboards are a fraction of an mm thick and are more flexible than the components that sit on them, its quite possible for a warped motherboard to experience failure after a certain amount of bending or the same amount of bending over time. FACT: We have had a number of libbys die, presumably due to warped motherboards causing cracking of the RAM chips or their joints to the motherboard. These include libbys that die despite having their spacers removed. FACT: We also have a number of libbys that have successfully been upgraded and have been running for quite a while without problems. FACT: It IS possible to make the hard drives a loose fit in the libby 50CT and 100CT. So loose that they can slide in and out under their own weight. I'm guessing this also applies to the 70CT and 110CT. FACT: As it comes from the factory, the original 8.5mm hard drive is hardly such a loose fit in either of the 2 libbys I've seen with the spacers in place. This seems to indicate that the Toshiba engineers had expected there to be some contact pressure between the hard drive and the motherboard. FACT: If you've got a hard drive thats putting NO pressure on the motherboard, it will NOT cause mechanical delamination of the motherboard or cracking of component joints. The problem you *might* have is if the new hard drive runs hotter than the old one and the board was not rated for such a high temperature. Remember, the libby only has a temp sensor on the processor, not on the hard drive or motherboard. I don't think this is likely but it is possible. FACT: A LOT of things can cause delamination of the motherboard or cracking of the component joints. Just because a hard drive was swapped doesn't mean that caused the problem. Like I said, I've experienced almost the SAME thing on a Tecra 500CDT (cracked component joints under a board). I'm willing to think this was due to my excessively enthusiastic typing as the board is right under the keyboard. Its certainly got nothing to do with the hard drive which is a good 1.5cm under it (its a real thick laptop). Other factors include botched repairs or openings, mechanical stresses, warping of the case itself and so on. FACT: ANYONE who's executing a DIY job on such a laptop has to accept some risk of damage. If you wanted something guaranteed, take the laptop to a professional who will fit an 8.5mm hard drive into the side by unscrewing the one panel and will replace the laptop if it ends up destroying it. I agree with Pres in that this is the safest way of doing things. However one must ask is the premium for an 8.5mm hard drive, combined with the effort of getting one worth it? In places where 8.5mm hard drives are readily available I'd say go for it. The rest of us have no other option. I searched for a month and a half for ANY 8.5mm hard drive round here, there wasn't one to be had. Now I've taken measures to prevent mechanical pressure being put on the motherboard. I think these measures are quite sufficient based on the fact that there is no mechanical pressure being placed on the motherboard from the hard drive. Of course, I can't say that this will definitely not cause problems but I don't see how it can. People can take all this with as many grains of salt as they wish and in the light of the fact that apparently people HAVE had damaged motherboards after replacing their hard drives. *phew* and after all that I'm still calm! ;-) Anyways thats my 2 cents on the issue, if anyone wants to respond (in a measured and non-accusationary way) please do so in the list and not personally to me. That way its on the record and forms part of the lively discussion. - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
