Hi


I wish to know if its possible to password protect a Drive or a particular Folder in Windows 7 Professional


Also,how much difference does an Antivirus make in a lappy battery performance I read a few Articles that claim that Security Essentials uses the least amount of Resources compared to others thereby causing less battery usage..


so do the antivirus play that great a role when it comes to laptop`s battery life? :mellow:

Thanks in Advance

Here is the password protection, which is good.

And yes, antiviruses use many resources so that the laptop battery performance may reduce. But don't know which one is better. Sorry!

Hi

On current machine I have 4 things open and unless I actively do something I run at around 0 to 1 percent CPU with 55 processes going currently. That includes Antivirus some other things.

Higher CPU will use more power, However I do not expect any modern AntiVirus to use enough CPU to see a difference in battery life.
That is of course an opinion, it is from some one that uses two laptops and a Desktop however.

In my opinion the mAH (milliampere-hour) rating of the battery as well as how old it is will have more of an impact on battery life.

If You want longer battery life, get the higher mAH rated battery.

Or reduce drain on the battery, Dim the screen, do not use the optical drive, switch from a hard drive to a SSD drive, Turn off the wireless if not needed, Don't do things that use the CPU at a higher level such as watching video, etc.

Good Luck
Roger
