Dell Inspiron 15R 5520 Won't turn on unless plugged into charger

I have the same problem with my 15R 5520 laptop. Anyone have any ideas what it could be?

Hi tpain,

We will have to check the status of the adapter in BIOS; if the adapter is not detected properly the system will continue to receive power but will not charge the battery. Please follow the steps mentioned below to check if the adapter is detected properly.

1. Start the computer by pressing the power button
2. Press the F2 key 2-3 times
3. you will now be on the BIOS screen
4. Under the Main Tab look for the option that says AC Adapter Type
5. If the Adapter Type says Unknown or None with the adapter plugged in.
6. Reconnect the adapter to the machine and if the status now shows as Unknown then the AC Adapter needs to be replaced.

Please let me know the findings.

Hello Ravi!

Yea  adapter appears fine, green light is on and doesn't flash. My battery charges normally and discharges normally. I ran the battery test on PC checkup and it passed on everything.

Again the problem seems to arise when I try to turn on my computer. Whether plugged in or unplugged in  it will power on for about 2 or 3 seconds and then turn off. However when plugged in it will power on for 2 or 3 seconds then turn off,  BUT THEN it will turn back on and boot into windows normally (about 50% of the time)

I took the battery out and just left the power cord in and turned it off to see what would happened. When i turned it on (without the battery in), it turns on for about 2 or 3 seconds then turns off. Then turns back on again and then boots normally into windows (about 50% of the time).

So in conclusion it turns "On" then "OFF" in a 2 second span With only the power cord, with only the battery, with both battery and power cord. 

The difference is that when plugged in, it sometimes WILL stay "on" and boot into windows normally. Where if it is unplugged it can never  boot into windows normally and just turns off.

anyways i appreciate your help!! it appears to be a motherboard issue as if something is short-circuiting, but i am uncertain. I also ran a full hardware test, and motherboard test on PC checkup-everything came back fine. 

thoughts?

Hi tpain,

I would suggest you to update the BIOS on the computer. Please enter your service tag # on the link below, then download the BIOS required onto the system and install it.

Please let me know if this helps.

OK i downloaded the new BIOS. when i go to msinfo32 it says i have the newest version now which is "dell Inc. A14, 5/13/2013"

So now what should I do?

Hi tpain,

Please check if the issue is fixed.

It did not fix the problem, the problem is worse now. Only starts up about 30% of the time now.

I took my laptop apart today, cleaned it, and took the motherboard out to see if anything was on it short circuiting it, but I didn't notice anything.

Anyways the problem still occurs and now I'm just leaving my computer on because I'm too nervous it will never turn back on again if i turn it off/ goes into hibernation.

So what do you think Ravi? Is it the motherboard? or the Power button circuit Board?

Hai

I have a Dell laptop 5520. When the battery level reached 7%, I decided to turn it off and connected the charger. Few minutes later I noticed that the pilot light on an adapter was off. I also discovered that the moment I connect the charger to the laptop pilot light goes off and almost three weeks now my laptop can't come on.

I have tried a good number of possible means yet to no avail. I also tried removing the battery, hold the power button for seconds and put back the battery sadly nothing seems to work out.

Kindly assist me.
