Anything to help extend the life of this laptop a little further. Dan

I've had this laptop for a really long time, and it's getting hot where I normally rest my right wrist while typing. I would have noticed this shortly after I bought it way back when. When it heats up, I cannot rest my wrist for more than a few seconds, that's not normal for this old beast. I tend to use my laptop when it's updating and I've only noticed this the last couple of times updating. It may be different now that I've reapplied the thermal paste to the northbridge CPU. I've also picked up one of those cooling pads just in case. I've set it up now to see if it makes any difference. I'll leave the laptop running Dan
