I have a Dell Inspiron 1720 that won't power up. I have tried 3 power bricks just to see if the power brick was the issue. None of them will power it up. So I am thinking that the internal power plug is dead. I tested the hard drive and it was good. Then memory is good. I am not real sure if the memory would cause the power issue, but I am testing all components that I can. When I try to power it up, the hard drive light stays on for 3-4 seconds and then turns off. The little 'power' icon above the hard drive 'icon' stays on the whole time it is plugged in. All 3 power bricks that I have tried have plenty of 'juice' for this model. The only thing I haven't tried so far is taking the bottom of the laptop off and looking at the internal power plug to see if there are any issues there. Help. All replies and opinions are greatly respected and appreciated.

It's more likely to be a faulty motherboard.

(Nothing to do with RAM. It would still power-on as far as the initial boot screen even if all the RAM was faulty or even missing, though you'd get a series of error-beeps of course).

Thanks for the reply. I talked to a tech friend of mine and he told me that, a fairly common issue that he has found in his experience with laptops with a lot of miles on them, is that the internal power jack has pins that connect it to the motherboard. Over time, the power jack will start to loosen with a lot of use and then these pins will disconnect from the motherboard. At that point he has re-soldered these pins to the motherboard. He told me that it is a tedious and not always successful operation. But you don't know that this is the issue with the power jack and it's connectors until you have the laptop torn apart to the motherboard. He said that it cost an average of $150.00 to check\repair. Being that the laptop is several years old, it becomes an issue of, do you want to put that kind of money into it on the 'chance' that it can be repaired. Any thoughts on this. Ever run across situation before?

I have one that is doing the exact same thing. It only will install the O/S on battery power, and that will work only until the reboot comes, then it will be out of charge. Nothing happens at all with the power cord plugged in, and I know that the cord, HDD and RAM all work. Anyone got any ideas?
