I installed RedHat Enterprise 64bit 5.4 on my hp Elitebook 8440p however the performance is disturbing. When I am typing, the computer seems to hang and repeats some keys. I also note that coping documents takes longer than expected. For example, copying a 3GB file takes almost 1hr 40mins.

The installation is on a different partition, fdisk -l output :

Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors

/dev/sda6      1464127488  1465147391      509952   83  Linux


/dev/sda2 ===> where redhat installation.
/dev/sda6 ===> redhat swap partition.

Partition table entries are not in disk order

What could be wrong with the installation because i followed all the required instructions.

First of all, why would you want to install RH Enterprise on a laptop? Could you try a live Linux session (of a non-server edition Linux)? Do you have the same problems there? – terdon Apr 14 '13 at 14:40
    
@terdon i installed redhat on the laptop since that is the only resource i have to learn how to use redhat. also i have my friends who have installed redhat on their laptops and its working fine. – glapo Apr 14 '13 at 14:46
    
Your hardware might not be supported as well as your friends hardware is. RH is made for stability - old, but proven, software. Not a lot of support for a modern laptop. – user168261 Apr 14 '13 at 15:04

If you know how to use rhel, you will be glad to use fedora (based on redhat and much more modern).

RHEL 5 is quite old and probably doesn't support the hardware in your machine well. You probably will need to run a more modern distro. RHEL 6 (or CentOS 6) should do.

Or just run a recent distro with Red Hat in a virtual machine.
