S96J Power Adapter Quiries

Hi Folks,

I just recently acquired an S96J with a T2400 processor and 1Gb 667 RAM. I would just like to know if the power adapter that usually comes with this notebook is rated 90W since I tried powering it through my car inverted rated 150W but it the notebook wouldn't flag its already AC plugged. Another problem Im seeing is the adpaters heat build-up. Is it normal for it to get very hot even on normal notebook use? I tried observing it without any applications running and it still gets very hot. Im basing my comparison with my thinkpad. How would you know by the way the adpater is 90W given that it says 19+V and 4.7A? Appreciate your responses.

Thanks,
Jaime

 

I'm pretty sure the power adapter isn't 90W. And yea, power adapters get pretty hot, it's normal.

 

P=I^2 * R = I * (V) = 4.7A * 19V= 89.3 W ~=90W

Heheh sorry, didn't mean to show off those honors physics skills

 

gator is right, you take the amps and multiply it with the volts and that will equal your watts.

Sometimes amps are displayed as mah, which is mili amps, like 5200mah, all you have to do i divide by 1000, and you get 5.2amps.

Knowing this helps with batterylife and discharge rates aswell, the lower the discharge rate the longer your batterylife will be.

For example your laptop uses 20watts per hour, this is your discharge rate, and your battery is a 60 watt battery, you divide the numbers and you should end up with 3 hours of battery life.

 

can you use a power adaptor that has more wattage but the same voltage .would the battery charge more quickly than ?
