Vista - External Monitor, extreme heat issue

My laptop is a Compaq Presario F504EA. I have had an external 19" LCD Monitor running sometimes in parallel and sometimes independantly with the laptop. It has its own Power supply, and is only connected to the laptop through a VGA cable.

I was wondering if this could cause the laptop to extremely overheat. With this, the laptop would be un touchable on the bottom side due to extreme heat.

I had also recently upgraded my ram from 1 to 2GB. Would this of had an effect on the heat aswell ?

It is currently in repair due to my keyboard being intermittent along with my wireless; i believe the heat as melted joints or something on the motherboard.

Thanks

when was the last time you spray dusted the laptop, that should help the heat issue. but adding more ram should not cause any more than normal heat, the extra monitor might cause more heat cause of the extra power going through the video card, but it should not make it untouchable.

i would try to spray dust the vents and also check to make sure all the fans are working.

Thanks Fadedrs for the reply.

I have this air canister which sprays the dust out. I have started to do this every other week or so.

It is currently out for repair and hopefully being fitted with a new fan. I will have to wait and see and hope the problem is resolved.

Cheers.
