Screwdriver to my laptop (Unknow type)

I'm thinking about changing the processor and the graphics in 2 months for my HP Compaq 6830s, and today tryng to open it, I was surprised to see what type of screws used just was different and unknow to me.

Anyway, it is curious why the screws on the top of the RAM and hard drive and WiFi are cross type and open the laptop in general use this type that is not what it is.

Here I leave the pictures of the screws. I hope someone wants me to indicate the name of those screws / screwdrivers and a photo of the driver.

Here the picture.

If you look it has 2 (points) at 180 ° from one another so that the cross (4 points) and 6-pointed star just don't fit, and in the center it has a circle.


In my life I have open about 3 laptops, one simply just needed a screwdriver, teh other were simply remove 4 screws down and the cover were opened, and the last one was more difficult since we had to unscrew the bottom and open at up side ,but the conclusion was the same: using cross-type screws.

If you want more photos just ask.

Sorry for Bad english

 

Sorry, photo isn't showing up...

 

Most are just phillips head, but that looks like it has a slot through it so flat head?

 

Is it any of those?

square/slot combination?

 

If you mean inside the center circle, in there it has nothing.

 

your picture is way too blurry to tell what it looks like. onecool's post has pretty much every screw ive ever seen so hopefully you figure it out from that

 

I have seen that before. it's a Combo-head, that takes a FLAT screwdriver all the way across OR a hex-head allen tip; The Allen key portion of those are stripped round, it's common. try using a flathead screwdriver all the way across to hitboth slots

 

use a flat blade and when you get the screws out change them for something else.

 

This.

Rep'd.

And then do this.
