Hi

I have a Dell e1705, about 2years old.
When i connect the charger just to a power socket
the green light on the charger comes on but when i plug the
the other end into the laptop the green light on the charger
goes off, I have taken the battery off the laptop and it still
does the same thing, and under both conditions the laptop will not
power up and no lights appear on it.
The only way i can get the light back on the charger is to unplug from
the laptop and wall socket and then just plug it back into the wall socket and the light appears.

I had recently put in a new videocard that i had to order from ebay since my old one died and the computer worked perfect for about a day....now this happened

Help!

It sounds like your board is shorting out the PSU. Are you sure your power jack on your motherboard is undamaged? Are you sure that the GPU you replaced is not shorting against the chassis ground?

A good way to test this is to "breadboard" the notebook - completely remove the motherboard from it's case and power it up using an external monitor and keyboard.

Ok i dont think that is going to happen...but it must have been something i damaged after putting the new card in because it was working fine afterwords for a few hours...Can you take the processor out of a Laptop Mobo?...not sure what my options are. How could it just short out randomly? Im not sure what to do it has frustrated me enough

Like I said, you need to breadboard the unit. Perhaps you installed the card incorrectly or seated it wrong, or while doing so dislodged something else..or even put a wrong screw somewhere, causing a short. The only way to take out all of those variables is to remove the casing from the notebook and reseat the card.

You can take the processor out of a notebook. I'm not sure why you would want to, in this case, though. It won't help you any.

1) take the battery out of your laptop and the laptop charger
2) plug your laptop charger in your laptop without the battery in it,
3) Try to turn it on the normal way:
If it turns on, then your battery has gone, (Its drained and run out of use like all batteries do)
if it stays off then its a charger problem
You would want to hope its a charger problem as they are cheap and easily replaceable
Hope i helped
I guess its a charger problem because its not turning on and the laptop automatically would use the charger as a main power supply if the battery doesn't work
and oh by the way
If the battery isn't in it, your laptop will act as a pc whereas if you plug the charger in it will work, but if you take it out while the laptop is on then it will go off instantly without a successful shutdown which could mean a loss of work
