/QUOTE]
anything that you already tried ,so that posters don't offer help that you already tried .
all i can say is because its not from Compaq ,then you really need to make sure its compatible with the laptop!
also was it plugged in when the dog chewed the cord!

hi yes it was plugged in when she chewed it

when i ordered lead it did say its compatable with my laptop

i have taken back off and took what i think is the memory cards out and tried without them and the same thing happens.

i dont really know alot about laptops but cant really afford to go to pc world

many thanks

Possible then that it shorted out your motherboard ! and it may never work again in its present state !

can i test this ?
if so how?

How much will it cost to repair?

cant test it on a help forum that for sure ,you will need to have a tech look at it . ,and as far as cost goes that depends on the severity of he problem, and what the local computer rate is in you area !.
