Laptop - slow install and operation

I am trying to install MEPIS to a HP / Compaq nx6125 laptop. The good thing is that even as a live CD it has automatically switched the LED for the on board wifi on. The problem is that it is incredibly slow and very unresponsive. (10- 15 sec lag from hitting arrow key to highlight moving in KDE menu, 60 secs to open a console) I thought that this was due to running off the CD so I have tried to install. This has take easily 2 hours and still not complete.

I have tried Ubuntu and the standard live disk installer was also incredibly slow and eventually stalled. Managed with alternative disk but could not even get the wifi led to light up. Suse 10.0, 10.1, FC5, PCLinux, Gentoo 2006.1 all install ok but wifi problems are frustrating me

Can anyone suggest how to get Mepis to run at an appropriate speed (this is so painfully slow that it cannot be correct) I read somewhere that KAT may be draingin resources so I did

killall kat
Kat: no process killed
killall katdaemon
katdaemon: no process killed
killall kded
skips to new line - no message

No noticeable improvement
Also the fans runs constantly at full revs. Is there a way to get it to cool only when required?

thanks in advance

no message means that process(es) called kded was killed.

Sounds more than odd, with those specs (Turion64, half a gig of ram), try
to see which processes consume most memory and/or cpu time. It could be because of a bad graphics card (or integrated), or something like that, but better make sure. I had problems with an Acer laptop before I found out Ubuntu didn't detect the correct display driver name, and once I switched that to the correct one (from the 'vesa'), it begun working slightly better (actually way better).

These HP laptops are supposed to be "linux friendly" but they do sometimes have problems.

I think the ACPI is not correct -- get the latest BIOS from the HP site

Try a boot parameter -- you add these at the the end of the boot line on the GRUB boot panel, probably ends in vga=791 -- cursor will be there
noapic nolapic

If you still have trouble Kanotix or Kanotix-64 will probably work very well on this laptop

kded is one of the highese CPU users in "top"

The really odd thing is that when first booted it seems to run at normal speed but it slows dow withing about 20 mins. At that point "top" is showing about 60 - 65% cpu usage with no user applications running. Ubuntu behaves in the same manner but Suse and FC5 don't - most strange.

I have installed FC5 currently (I am trying to settle on one distro that will work all either with the internal wifi or with the 3com card that I have spare) but I am still experimenting a bit.

I will check though the links and may give Kanotix a try

Thanks for your advice
