If your Dell Notebook PC is having issues starting up, then the following articles will take you through the most common reasons why and how to run through the most common checks to identify where your PC has gone wrong.
If so there are several basic questions to ask so you can troubleshoot the issue further.
If you have ruled out the other issues then we are left with troubleshooting a No Power issue. The first thing to do is to check the power coming in to the system. There are three main methods of powering a notebook system. They are:
Check for any status LEDs on the Battery, A.C. Adapter and dock.
If they all have a status LED seen then go back to section 1 and ensure this isn't some other start-up issue.
If any part doesn't have a status LED then test them while they are disconnected from the notebook system. If they still don't have any LEDs seen at that point then it looks like that particular part is faulty. I would proceed with the rest of the guide to ensure no other issues and contact your Technical Support to take this further.
If the parts have a status LED when disconnected from the system, but the LED goes off only if it's connected to the machine then go to section 5.
Disconnect all three parts and try starting the system up with each part connected individually.
If the system is shown to work with a particular part removed, try connecting a working substitute part from the same model and try the suspect part in your known good working substitute system. Does the fault follow the part or stay with the machine?
You should be able to keep working in the meantime using the other 2 parts for power.
If the issue follows the part then contact your Technical Support about this.
If It says with the machine then contact your Technical Support to take this further.
If it happens with both, then again contact your Technical Support to take this further.
If the system is shown to have failed in the same way with each part in turn then we will need to further troubleshoot the system in the next step.
If we've ruled out the Power peripherals then we're only left with troubleshooting the system itself. The most common reasons for a No Power is that either a miss-fitted or faulty part is shorting the system and preventing it from starting or the power circuit on the motherboard isn't distributing the power correctly to supply enough to start-up the system.
I would advise removing as many parts from the system as possible and power the machine on with those parts removed.
i.e. Hard Drive, CD/DVD Drive, Memory, WiFi card, 3G card, Bluetooth card and any additional parts added to the unit such as removable media and flash memory.
If it starts powering on then it is a case of putting the parts back one at a time with a power on attempt after each part is fitted. to see at which point the fault returns. Whichever part you've just fitted at that point is most likely causing the fault. If it doesn't return and you've fitted all the parts, the it was a miss-fitted part.
If it doesn't give any signs of life with the internal parts removed then contact technical support for further aid with this.
If you are unable to troubleshoot further please contact your Technical Support for further help.
