This laptop came with Vista installed, but I immediately replaced it with Debian.

Except for the part about writing a script, I have no idea about how to do that. Can you attach a copy of your script to the email (and does Debian's list server forward attachments?) or can you upload the script to a pastebin website or something? That would at least give me an idea of what commands I would need to use. > 3) I've also found out that nothing helps as much as regular cleaning > all the orifices of my laptop with an industrial-grade vacuum cleaner. I'll definitely give that a try, like the earlier post suggested. An "industrial-grade vacuum cleaner" sounds like a floor-cleaning model, so the same concern comes to mind about particles in the vacuum, though. > 4) And, yes, *no two* graphics drivers behave the same with regard to > overheating; IMHE, the proprietary fglrx ATI drivers have less > overheating problems than the radeon and the vesa/framebuffer drivers. Hmm. Maybe they have some of that secret technology you talked about. > There, my 2 euro cents (as a matter of fact, is there a key combination > for obtaining the euro cent sign, as there is AltGr-E for €?) Wish I could help with that. Unfortunately, I'm in the US, where we know very little about AltGr keys (or their combinations). > -- > Good luck, > > Klistvud > Certifiable Loonix User #481801 > Thanks, Brian -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
