Voltage question, noob

I have a Vaio VGC-RB30. I was just noticing on the back there is a little red switch. It has always been slide to the left, with 115 showing on the right. I can switch it to the right and have 230 on the left showing.

My question is, the number that is showing the voltage being supplied? Should I have it at 230 to help my PC suck up as much juice needed for games?

Thanks!:cool

 

Leave it at 115
It's the voltage of the receptacle that your PC is plugged into

 

So changing it to 230 won't do anything? Leaving it at 115 is the way to go, since it was like that when I got it?

 

As ASUS said "Leave it at 115 - It's the voltage of the receptacle that your PC is plugged into"

115 is "standard" household voltage supply. Lamps, toasters, TV's, clocks, etc.

230 is for things like elecric stoves/ranges, hot water tanks, etc. If you switch it to 230 it won't run, and it could possibly damage some components.

 

Actually I did switch it to 230 and my PC wouldn't start this morning.........For some reason after 15 mintues it did start. I realllllly hope I did not f$$k something up. I am an idiot.

 

As the others said, leave it at 115 volts (or don't try moving it to 230v again, at least).

I think the reason it's there is that in some countries the standard line voltage is 230v and the switch allows you, if you're a business traveler for example, to use your laptop in countries that have the 230v electrical standard.

Most desktop computers' power supplies have a similar red switch, but many people never even realize it's there. Not likely someone's going to be moving a desktop machine back and forth between countries with different electrical standards, but I suppose the power supply manufacturers include the switch so they don't have to manufacture two versions of each model they make to be able to sell them in different countries.

 

Ask your parents or teacher for some urgent electrical safety advice.

its the volts what jolts
but the mills what kills

 

I messed up my PC. Please refer to new post
