Kindly help me resolving the problem of :
1. Overheating : its heated so much that, you cannot touch the base of laptop
2. Battery consumption : Battery gets reduced quickly
3. IDT Sound Drivers officially came with HP. But i am not able to find one for Ubuntu. Default sound of Ubuntu is very very low.
4. How to protect my PC from virus/intruders.
5. Display driver is AMD Raedon 7600 HD with 3d. But i am not able to configure it in Ubuntu.

I have not faced such problem on Windows 8 Pro.

Kindly help me.

i really loved the OS. If these issues can be sorted out, then I think its best in the market.

You have a switchable GPU which can cause all manner of Hell in Linux. Nvidia and AMD both stated they would not be supporting anything but Windows but then Nvidia did subsequently join thrle Lunux Foundation. This is the only link I know that may help.

You don't need AV in Linux unless you run a mail server or a file server with Windows clients

Hey...
My question was "My battery gets reduced drastically and Laptop Temperature rises very much".

If I use Windows 8 Pro, they battery would easily survive for an average 3 Hours, but with Ubuntu it would hardly survive for 1.5 Hrs.

So any help from Ubuntu on this.

Also the temperature of the laptop rises so much that I hardly can touch the base of laptop. It didn't happen with Windows 8.

So Kindly help in getting these issues resolved. If nothing can be done, I afraid that I might need to go back to Microsoft.

Hi Gaurav Dighe (gauravdighe),

I will try to answer as much as I can to your multiple questions . Shortly.

1) Try to install the closed source drivers (AMD/ATI) and see if this helps. Open a terminal (CTRL+ALT+T) and apply the following commands:
     sudo apt-get update
     sudo apt-get upgrade
     sudo apt-get install fglrx-updates fglrx-amdcccle-updates
     sudo amdconfig --initial -f
Reboot your system and re-check the temperature. Also you can open the Catalyst control center and search for some option related to performance..

2) Same as above , when you install successfully the AMD/ATI driver and Catalyst control center , search for some option related to performance and reduce it. Also the screen back-light matters here. Try to reduce it as well.

3) Drivers that are exist in Windows , are not exist in Linux.(I mean you cannot install a Windows driver in Linux).
Open the "sound settings" and try to increase the sound beyond 100%.

4) Safety in Linux is not the same as Windows. Viruses ... etc are not "survive" in a Linux environment because 95% of them are written for a Windows OS. Although if you want an antivirus , some of them exist in Linux. Search in software center for antivirus and you will see.

5) same answer as 1 & 2. Install the closed source driver (by issuing the above commands one by one) and reboot your system.
