The power cord light does not lightup any more and will not charge the battery or run off A/C power.The light on the power pack box is lit and when I take a volt meter to the end plug there is no power when I touch one lead to the center electrode and the other lead to the outside of the plug. There is a reading of 19.5v when I touch the lead on the volt meter to the outer plug and the inner part of the plug surface but not the center electrode. I did notice the other day since I have battery bar I noticed it had showed it connected and disconnected on and off before it stoped working. Is this a power cord issue or something more serious like the main plug on the laptop or mother board?
Yes, if you have the skills and equipment. It's not a job for a handheld soldering iron - you need the right equipment. If you don't have it, a good computer shop (not a parts-swapper) can replace the jack. Expect to pay $150 or so for the job to have it done right.
so even though a motherboard says XD299 it could still have the NVidia so make sure to ask for one that has the Intel Chipset correct? Or does the XD299 stand for the Intel chipset?
You do have the nVidia video chip. Unless you're willing to gamble, I wouldn't replace it with another nVidia board -- the chips are notorious for high failure rates.
The Intel-video version will be more reliable - and since you won't get much of a warranty with a replacement board, that's reasonably important. In some cases you may need a new heatsink - in at least some models, the Intel version uses a different heatsink from the nVidia.
Are you sure, since everything I found last night says i have the Intel chip which is denoted by the PN# XD299 which I have a tag on my motherboard that has that PN#. The Nvidia chiped board has a PN# of F923K. So according to what ive found I have the Intel chip and not the Nvidia.
