Computer is slower, is something going on here [SOLVED]
« on: September 14, 2014, 03:17:07 pm »
My web browsing is really slow, slower than usual.  I added 1 GB memory to this old machine and it was working good at the beginning. (IBM Thinkpad R40 2003) I have added a screenshot. The memory does not show 1GB memory
and the CPU usage says 100% but I'm only using the chromium web browser and something called lxtask. see attached screenshot.

it is only showing 512 megs ram so i would check the chip you put into it and make sure it is a 1 gig ram chip, as far as i know the r40 can handle up to 2 gigs ram 1 gig per slot...  Now if you have 2 512 meg chips in it for a total of 1 gig then it appears one of the chips is not seated correctly or not working...

Sorry for being rudimentary, but...

If it happens again, and you need to take your laptop apart anyway to re-seat the RAM, may I suggest running a clean pencil eraser, e.g. "pinky" over the contacts?

The 'gold-plated' contacts, on these things, tend to corrode over time, and it's invisible to the naked eye.  It doesn't take much.  There's very little current running through the contact surfaces.

I've resurrected countless computers, over the years, by simply running an erasure over the contacts, especially if they've been used in a 'smoking' environment, or around pet dander.   ;)
