Once my machine was warmed up, any touching of the keyboard, touchpad or even the palm rest would cause enough interference.
The card I needed was 32MB. I first got a card on eBay that I thought would be right, but turned out to be the 64MB card. It didn't work at all, but the guy took it back. It was resold (item 6745243292). You need to make sure it is the right version. They all are called FMC2G1. This item was sold saying it is compatible with all the models, but I believe it will only work in a S701, S702 and S901. You might send an email to the buyer of that item and see if he is getting the right card, although I had no way to check that the card worked. The Toshiba part number of the 32MB card is P000341430, while the 64MB card is P000349220. I think that the 64MB card may be available from Toshiba, but the 32MB card is harder to find. As far as taking it apart, it is harder than a desktop machine. Here's what I remember: Take out the battery. You need to remove the keyboard by popping off the plastic piece over the on/off switches to expose 2 screws. The KB swings up. The ribbon cables need to be released. The plastic piece where they attach to the MB need to be pried up about 1/16". I think there is 1 ribbon for the KB, one for the touchpad, one for the little LCD. There are also 2 cables to the video card, one to the on/off switch and one for speakers. There are 4 screws under the KB. Lots of the screws on the bottom need to come out, including 1 in the hard disk space. I took one little one out under the battery, but I never knew if it was needed. There was one under the phone/ethernet jacks. The video card is held by 2 screws. In my case, the case and the keyboard were discolored from heat, right over the video chip.
I came away thinking that they made it extra hard to take apart just to keep people out. Unfortunately, I didn't take any pictures. Keep track of what screw goes where. There are lots of sizes. You can send me an email if you start to take it apart and have questions. Here is an online site where they say you can get the 64MB card.http://www.sparepartswarehouse.com/T...top,Parts.aspx
The price for exchange is less than the guy paid on eBay. I think your old card will qualify for exchange pricing, unless you spilled coffee or something on it.
I think dealers can get the 32MB card if they lie to Toshiba and say it is for an extended warranty. Mine came in a Toshiba box.
