Dell Inspiron15R (7520) not booting

Hi Dellusr123

The symptom indicates as a hardware failure (Motherboard). Could be a short-circuit with the AC adapter port.

You may also try using a known good AC adapter. Try removing the Adapter and battery from the computer. Re-seat the power cord bricks in the adapter and then connect only the adapter start the computer.

 May also need information if the system is still under warranty.

Do let me know if you have further queries.

Hi Dell-Geoffrey,

Thanks for your reply. I'll try and find a good AC adaptor tomorrow. It's strange that the green LED on the brick part of the AC adaptor goes out immediately when plugged into the laptop but re-appears a few moments later when disconnected from the laptop.

The laptop will be 2 years old next month and it hasn't got warranty any more. 

Hi DELLUSR123,

Were you able to try a known good AC adapter?

Do let me know if you have further queries.

When the LED on the adapter goes out on connecting the system, the mainboard is bad.

Hi Dell-Geoffrey,

Yes, I managed to borrow a  working AC adapter. Unfortunately , this too had the same result when plugged into the laptop.

i.e. the LED on the AC adapter goes off immediately when connected to the laptop and no response from the laptop when the power on button is pressed.

Any ideas ?

Thanks EJN63.

I guess it'll be pretty difficult and expensive to fix ?  

Quite disappointed that this laptop didn't even last 2 years !

I have had very similar behavior for the past several months. 

If I leave the laptop off but plugged in the battery will charge in 24-30 hours and then I can use it for 2 hours until the battery drains.

If I remove the battery the system boots and works.  I have tried a different adapter, same issues.

I'm confused on whether this is a battery issue or a main board.

Can someone tell me if this is covered under my warranty which runs out in 10 days?

my service tag is 3QVQGW1

Thanks
