Question:

Power cable question?

I have a hp laptop from south asia. The adapter connects with the laptop and the power cable. The power cable has a 3 round pin plug which says 6A 240V~. On the hp adapter for the input it says: 100-240V~ 1.6A 5-60Hz. It also says Connect Only to Grounded outlets.Now I am in canada. All i know is that here they have 120 V in normal power plugs. Also they have 1 round and 2 rectangular pins to plug in the outlet.I bought this adapter which basically connects the 3 round pin plug into the adapter and the adapter has 3 canadian pins. The thing is that it says 250V 10A on the adapter. So I am not sure if it will hurt my laptop if I use it. I am a bit confused because Canada has 120V and the adapter accepts 250V. The HP adapter has a range from 100-240V. Will this be ok to use since the HP adapter will just convert the 120V into the proper output for the laptop or do I need one the expensice Voltage converters for the laptop?

Answer:

yes it will be fine
It will work fine on 120 or 250 volts, the grounded outlet is for your safety, most places in Asia are doing away with the round plugs ok.....
ok here is what i would do .. (get a cheap 5 dollar volt meter at radio shack or such. ) it dont have to be digital or fancy , just need voltage reads.. unplug the lap top from the cord, plug in the adapter with the cord NOT IN THE COMPUTER. take the volt meter , and set it to read dc voltage 250v or above . read the volts comming out of the end of the cord using the meter.. is it less then 250 volts , then you should be good .. if you dont know how to read a volt meter, or know a handy neighbor with one , who knows how to us it , go ask them to read the cord for you , tell them you need to know the voltage output while connected to canadian power from the cord..
It is fine, your power cable has a power rating of 6A @ 240V and your hp adapter can handle an input of 100-240V~ 1.6A 50-60Hz right? Then, you bought an adapter which has 10A 250V capacity and it is no problem handling your cable and hp adapter which has a lower power requirement. And also, the most important, in your area, the supply is 120V and your hp can handle from 100-240V and your adapter up to 250V, so there is nothing to worry about, as long as the supply voltage is lower than of the required of your hp, mind it if your supply voltage is 240V and your hp says it handles 120V for it will burn your adapter..............
