E7250 want power on

Hi alexaskis,

Thanks for posting.  Apologies that your system is not performing as expected.

Unfortunately from what you've described, it sounds like the motherboard may have failed.

Here is information from the Dell knowledge base you may find helpful:

Dell PC does not turn on or boot into Windows

I found just the same problem in my E7250 just after update the BIOS to version A20. The laptop was not receiving any power, even the white light in the charger stood off when it was connected (it seemed to have a short circuit inside). As the warranty period is expected and I live in a small village in Europe, I sent the laptop to a local technical support. They told me a condenser was burned and they replaced it. However the problem repeated (the same condenser failed) one week later. I did not have any problem with the laptop for 3 years and reading the problem described above I wonder if there is some relation between the condenser break (which causes the power problem) and the BIOS A20 upgrade. I would appreciate any information about this matter. Thanks in advance. Best regards.

I Had the same issue now with Three E7250 Laptops (out of warranty) in two days, on the first one i have replaced the motherboard and in less than 5 min of working fine it stopped. another model was stocked I opened it with new power adapter, it booted into windows and then the same thing happened. I'm starting to question if Dell somehow intentionally design these laptop to fail after life span, or something else is going on!!!

I have an E7250 under use of my daughter who plays games on it. After working for couple of months it won't come on charging. After changing adapter I checked dc socket and found the two black wires on it were burnt at the contacts to the board. I replaced dc socket and it resolved the issue.

Now again after 2 months same problem is arising and when I checked the dc socket, I found the same 2 black wires at connecting socket going black, that is due to over heating. 

This seems to be a design flaw, where these wires are over heating under stress and consequently failing.

The dc socket component should have been designed to cater to the maximum power requirement under stress and should not get burnt which is a safety issue as well. 

Lastly Dell should give complimentary dc sockets to every customer who purchased model E7250 as a good will gesture to retain its customers. 

Incidently I also have an HP 2560p with no such issues.
