Question about Computers & Internet
When the power cord is connected, the system won't turn on. Even when the power source is switched to the carrying case's battery pack, the system still doesn't respond to the power being turned on.
You have made an attempt to power up using both forms of energy. Generally, the indication is an internal power failure on the circuit board itself. If when previously used, a power surge damaged the 1st stage section, a shot may occur and render the unit useless. The only way to know for certain is a bench testing of the unit in question.

When lithium batteries discharge past 1.5 volts they can cause havock. Take the battery out of the system (if this is the one that discharged I would throw it away), disconnect the AC and try turning on the system. Of course it won't come on but If there's been a clitch, this tends to clear the system. Then put in a fresh battery and connect the AC. If this doesn't work then buy an external box for your present hard drive and connect it to your new computer to get your data.

Possible heat issue. Check the cooling fans and see if theyre running. Usually one on the bottom, back or side of the laptop. Make sure that the cooling vents arent blocked during use.

By dumping the power while running you have trashed your Operating System or blown up the Ram
Insert your OS disk and see if it comes to life , if it does then you may have to try a repair from the OS installation CD
If you have popped the Ram then the only solution is to get it checked out on another PC

First thing to try is another power supply. They go out. They run at less effenciecies sometimes, and other times they just stop. The inverters get really hot when we use them for a while and they usually get banged around a bit too. When they heat and cool repeatedly, the chips inside expand and contract and over time they crack their soldering in the boards and they lose contact. If one were to have come loose all together and have bounced around inside until it caught on something, that could be your short. Something could have just gotten into the cooling vents on your power inverter too if it has them. Try swapping out with someone else that has a Dell if you can to see if it works, or take it into a repair shop and ask them if they can check it with a good inverter for you. I would think any decent repair place should do this for you at no charge and it would take them 2 min. You can find universal ones for much much less than a standard Dell replacement as well if that's what it is. I know the Dell OEM inverters are over $100 and universal replacement ones are from $25 to $40 on average.

Any lights on the A/C power adapter ?? If not, then the power adapter is faulty. If the adapter is OK, the power connector on your Lifebook is faulty. Good luck
