> memory I should buy for my Acer Aspire 5633WLMI laptop and it duly
> advised on a 2GB PC2-4200 CL4 stick. So I recieved it in 3 days and
> installed it on 20/03/08. I noticed no problems untill the 22/03/08 when
> the machine started to make a continuous beeping sound after power on.

> The only way I could get it to boot was to press the spacebar or esc
> key, it then booted Vista but I noticed the tap function of the touchpad
> wasnt working, as well as not being able to select certain things when
> using the left button. At first I thought the touchpad circuitary was on
> its way out but then it occured to me that maybe it was the new memory
> I`d installed, so I removed the new 2GB stick and the problem hasnt
> occured since.

> I am RMAing the stick back to Crucial and hope to recieve one that works
> properly, it shouldnt be a compatibility issue as it was guaranteed to
> work with my laptop, I just hope the stick is faulty and that a new one
