Specific Comments Guys:-
Phil L. - Mine was the 4GB DDR3 model with Intel Core 2 Duo, Intel Series 4 Graphics and ralink 3090 wireless card.
1.Installed Kubuntu 11.04 from live CD (GUI Install)
2.Everything worked fine “out of the box” except wireless connection tended to drop out, changing wireless configuration caused a hardware crash. Faulty wireless driver causing great instability. (Easy Fix)

 a) Download and installed Markus Heberling's Ralink 3090 Driver .deb package from
 b) Blacklisted the current driver 
    i)sudo gedit /etc/modprobe.d/blacklist
    ii)add Blacklist rt2800pci to the text file
    iii)save and reboot

3. System stable everything functional.


  • Unordered List Item Battery life seems extended from original windows 7 install.
  • Unordered List Item Intermittent crash of flash player when watching on-line videos, Fixed on Refresh.
  • Unordered List Item All desktop graphical effects work without hindering performance

John B. mine was enhanced to 4mb compaq 620 wzo40pa
1. I loaded RHEA Entreprise Server 5 on HDD.
2. Go to BIOS and disable SATA option and enable IDE option before installing OS. Do it the Device Configuration part of the BIOS. - John B
3. GUI Install Failed… John B
4. Did a Text Install … John B
5. System GUI failed… upon installation… X server did not come up….John B
6. Spent next 18 hours to get this work around.

6a. Xorg -configure

 This creates file

6b. Xorg -config
6c. USB will work
6d. mount /dev/sda1 /media

—- John B Solomon

Still the Network adapter was not working.
Needed a Manual work around.
Bring down the NIC
1. /etc/rc.d/init.d/network stop
2. Download the Realtek linux driver 8101 from the net
2a.Procedure to install
2d.make install
3./lib/modules/<KERNAL VERSION>/kernel/drivers/net
4.gvim /etc/modprobe.conf
5.alias eth0 8101

You NIC should be up - John B Solomon


Works pretty smooth with RHEA 5 Server and Ubuntu LTS 10.0.4 (Installed on a Flash no display Issues unlike RHEA) - John B Solomon

Works 90% out of the box with Kubuntu 11.04, a 5 minute fix (described above) brings this to 100% with no performance issues and an extremely smooth running system. Boots quickly, loads applications quickly,increased battery efficiency and less hassle all round compared to the original windows 7 install. Phil J Lange

I have the same configuration as Tomek, but a Compaq 620. Everything works OOTB as mentioned. I have a ralink 3090 wireless card. If the blacklisting does not work check the /boot/config-2xxxx file and find statements with CONFIG_RFKILL_xx and set all parameters from y to n and then reboot. The wireless should now work.

HP 620 (WT162EA) with preinstalled SLED 11 SP1
CPU: Intel® Celeron® T3000 (1,80 GHz, 1 MB L2, FSB 800 MHz)
Network: Wi-Fi Ralink 802.11b/g/n (rt3090)
Other specification is quite the same.

On SLED everything works out of the box.

I have changed to Ubunut 10.10 amd64.
There was only problem with wi-fi.
Add to /etc/modprobe.d/blacklist.conf following line

blacklist rt2800pci

Full report on Ubuntu 10.10:

Processor WORKS OOTB
Optical Drive: WORKS OOTB
Graphics: WORKS OOTB
Ethernet: WORKS OOTB
Wireless: WORKS with blacklisted rt2800pci
Bluetooth: Not Tested
Modem: Not Tested
Card Reader: WORKS OOTB
ExpressCard Slot: Not Tested

3G Modem Hauwei e17050c USB: WORKS OOTB

Functional keys: WORKS

could you, please, send your grub configuration and xorg.conf?
I have the same notebook (HP 620) and I installed Fedora 14 instead of SLED 11.
I have a problem during notebook startup - it probes video modes and it makes Linux very slow.
Does anybody know how it is possible to fix this?

Thank you,
