Hi Guys I have a laptop that was dropped off for me to look at. The girl said they had a simmilar problem not too long ago and had to change the power chord and batery and it worked for a little while but is back to the same thing. What happens is when you plug in the laptop to the wall it doesn't recognize the ac adapter as the lights on the front don't light up. (both the one showing the battery charging and the ac light will not light up). I used my multimeter and checked the ac adapter and it is giving the right voltage to the laptop, I checked it hooked up to the laptop and checked the ac jack on the laptop and it is receiving the voltage so I know it is making a connection to the ac adapter. Now I checked the prongs that the battery connects to and from reading it said that there should be 1.4 volts going to the battery and when I checked I was getting .7 from the first and .7 from the second prong (Is this the way it is supposed to be .7+.7=1.4 or should both be 1.4? This tells me that the power is going through the laptop but why is it still not charging or even recognize the ac adapter is plugged in? Is there any other place I can check to help identify the problem or what should I tell her she will need to buy(battery,etc)?
