Re: advice on upgrading hard drive and cpu of laptop
I think you are speaking something of what I am looking for here!!
I have been thinking seriously about upgrading my lap-top, which has
survived long...
I have a "toy" 486 lap-top (486 DX4 75 Mhz to be precise) And how can I
upgrade the processor etc on this please!!
My laptop is a Compaq LTE Elite 4/75 CX
any places where I can get info on how to upgrade this lap-top?? from 486
to say a reasonable speed pentium processor??
thanks in advance!!
