I don't think there is much differance, my libby reports about 5 1/2 hours usually but I notice I don't have to plug in the adapter now until I am ready to shut down. It kinda did that before but not so routinely. Battery life is so dependant on what a person is doing. Where I really notice a differance is in spin up times. There are none, with a hard drive spin up times were very noticeable. > > Sometimes I feel a bit sorry to have decommissioned > my L110; it merely > serves as a sort of book stand, right on top of a What do you use in place of it? I tried the U100 but it fried like twice on me. It was a piece of junk. They run too hot and Toshiba doesn't cover them under warrenty.

(I > remember you were busy with that). There were some > guys who have fitted And still am:). I am fitting a wire buss to an old libretto 32MB ram upgrade board. I am going to solder the buss to a couple, maybe three, of so-dimm sockets. I am going to run the so-dimm sockets into the hard drive bay, where I have room now (I was just waiting until compact flash capacity got large enough to use as a hard drive so I could try this and have space inside the libretto), and try using standard so-dimm edo plug-in modules. It is slow going because I don't have anywhere to work and lack tools. I don't think I'll have to remove the soldered chips on the motherboard. I have also been thinking of installing a sdram controller and use sdram but all of that is very hard to do since all I have is the memory upgrade port to use for access. The hard drive bay is a great place for all kinds of fun!! > a Portege 64 MB module in the extension slot to get > 96 MB; that was the > max I've ever heard of w.r.t. Lib110..... Yes I remember the upgrade. I am sure the libretto can handle ram up to, at least, 512MB and 8 socketed modules. john > > Best wishes, > > Philip > > > > __________________________________________________ Do You Yahoo!?
