Processor speed problem


Hello, I would like to say thank you to everyone in advance that attempts to help me with my problem. Today I noticed that my Slackware 9 system was running rather slow, so I decided to take a look at Info Center, and then proceeded to the Processor tab. I am running a IBM Thinkpad 600E which has a 300mhz processor. When I go to the processor tab under info center, it reports that my processor is running at 75.458mhz. This wasn't doing this yesterday, and I haven't changed anything on my system in that time. I haven't encountered a problem like this before in linux, and after I spent good while of today googling for a solution, I am no farther ahead then when I started. Please advise, Thanks

# Find CPU specifications
cat /proc/cpuinfo

What is the output of that command?

That's strange. Is the power supply OK? CPU temp? Anything you can see in /var/log/messages?

I have noticed that the setting of the hardware clock can bum out the bios cpu clock settings on my computers - it is a rare occurance, but it can happen.

I have altered the /etc/rc.d/rc.6 script, just commented out the hardware clock part. No more problems.

Everything in /var/log/messages seems to be unchanged as it has been before. Strange is right, I've been working with Linux for quite some time now and have never encountered a problem such as this. Power suppy seems to be OK, nothing changed. Any other suggestions?

Tried, rebooted, still the same. Any other suggestions?

Sounds as if something in your clocking circuits has gone bad since the orig speed /4.

Search google? It sounds like a bad intergrated circuit on the motherboard, but I have never messed with a laptop.

Will search more. Think it could be possible that some program is limiting how fast the processor is working? If worse comes to worse, I may end up doing a re-install and see what happens...

Do a quick check of the BIOS and make sure the CPU clock speed is set correctly. If so, try loading DOS 5 or higher on a fat partition and see what processor speed it reports during boot up. Much faster than wiping and reinstalling Slack.

It looked like bios setting had been changed. I'd also suggest the same like Lepper Messiah said. Normally after booting DOS display that classic table stating the CPU and RAM capacities.

Or just observe carefully the screen during booting (bios loading), possibly hit the "pause" key to halt the system booting for better reading.

If it stated that ur CPU speed is 75 MH, then ur Bios setting had really changed, then u need to go into bios setting. If DOS displayed 300MH, then it might be caused by missusing of software or ur installation might has problem (really strange case).

In case u have to setup bios, CPU speed is normally =
BUS-speed x multiplier factor

For the 586-family of that time it would be likely that ur bus speed is of PCI bus speed (either 60 or 66), multiplier factor maybe 5, see ur hardware documentation, check the vendor site for hardware related tweaking ..

You of course have to reset cpu frequencies through the bios. If you have hardware jumpers though, forget everything I said totally, it's not applicable.
