3- the model i got is hp pavilion dv4131ea IS ea mean something?
4- is all pavilion dv4000 series have 915 chipset?

It is worth your time to upgrade the hard drive to 5400 rpm, you will see a very large performance increase.

 

The CD drawer on laptop drive only pops out a little cause it uses a spring whereas a desktop drive use gears or belts to push the tray out.

 

1 - It is quite normal. As zazonz said and given the space restrictions they just come out little and you"ll have to pull it out fully.

2 - Yes, I think it will increase performance to a large extent, but it might not be immediately noticable.

3 - dv4xxxEA - model specific to be sold in Europe, dv4xxxUS - specific for the US and so on...

4 - I think it does, but to be certain try CPU-Z . It is pretty good in getting info on the chipset, processor, memory etc..

 

Thanks for all
