I hace a compaq presario 700 . I added 256 memory

256 mb is a little small for your laptop.1/4 of a gig.

some laptop need only one type of memory
so you may have the wrong type.

try taking you 256 memory and boot if it works then try taking the old memory out and put the 256 memory in ( on it's own )
and boot to see it there is a conflict with the memory types.

when i go for memory i take the old one with me to the shop so i get the same type and i normaly go for a gig or 2 :)
as 256 is not worth much 256 on its own will get your pc / laptop running till you try and use it to E.I. surf ect it will be as slow as a snail.
but if it runs with the 256 then they might not be compatable with each other
I had this problem befor.

Remove the memory ... try again ...

there is the possibility your memory was not seated correctly and/or it is not the correct memory.

remove it to get going again ...

256 is a strange number ...

please go to www.4allmemory.com and have them scan your computer. They will make recommendations based on that scan. Compare what you got with their recommendation.
