I am using HP probook 4420s model with i3 processor, 3 GB RAM. Can I use SSD 128 GB drive with 8 GB RAM? Currently I am using Window 7 32 bit and wanted to change OS to ubuntu 12.04. So my question is, Will my laptop support SSD 128 GB Drive, 8 GB RAM with Ubuntu 12.04 64 bit OS? Please help me by your suggestion.

I am using hp probook 4420s with ubuntu 12.04 beta1. i am a regular user of ubuntu since 8.04. I started using the hp probook from 10.04 and since then awaiting additional drivers for this machine in ubuntu. but it works with standard grafics driver and hence no color and brightness control. When can we expect the drivers for this machine in ubuntu.

Ubuntu 11.04 alpha 3 fixed a lot of issues on this laptop, especially wireless. I'd recommend it, or waiting for the beta if it's a mission critical computer.

I am using Fedora 13 on my Probook 4420s laptop for the last 6 mnths.Fedora runs on it quite smoothly..without any conflicts…supports full compiz effects….without any glitches.I am also successfully running “BlackTrack4 r2” as a guest OS…Its great!!!!

M using

i3 370m, 3gb, intel HD graphics, 320gb.

To those who have difficulty in enabling their wireless, specifically for ubuntu 10.10, could try this.

System → Administration → Additional Drivers → STA

Try that method first before trying other solutions such as 'fwcutter' and such. I find the STA method works simpler.

Of course, you'll need to connect the laptop to a wired network for it to happen.

Hope this helps someone.

I tried installing ubuntu 9.10 on hp probook 4420s…but there's no display. I tried running the live version from the DVD, after a while i can hear the starting music, but screen is blank. I tried 'install ubuntu', the cursor blinks for a while, then it goes blank and it just wont show anything! I tried 'check disk for error', but the same thing happens! I've got no clue what's going on. You see, I'm a newbie in this linux thing. I had similar problem with one of my desktops, it was quite old, so i thought it was some compatibility issue, but i don't think that should be happening in this computer.
Can anyone suggest me some solution?

I had the same problem with my HP ProBook 4520s
I am almost 100% sure that you will be able to install Ubuntu 10.04. The problem is that version 9.10 does not support your graphics by default, hence the no display. I did get 9.10 to eventually show the graphics after I changed a 100 settings, but the screen was jumping as the mouse cursor got near the screen edges. So I downloaded Kubuntu 10.04 and installed it with no problems at all. Hope this helps…after all 10.04 should be the better version ;)

After making settings for two hours I still had graphical problems with Kubuntu 9.10 that was installed on this notebook/probook. Screen resolution will revert back which resets the toolbar and all widgets.

Kubuntu 10.04 LTS Lucid Lynx is working perfectly without having to configure a single thing. It took me freakin 5 hours to realize that the upgrade would actually work better which took me a total of less than 1 hour to install and configure according to my needs.

The thing is this, if you buy a brand new laptop, consider upgrading your distro too - which at the end of the day is better!!!
