Laptop Details:

    Dell Inspiron 15R N5010
    4GB RAM - 500 GB HDD
    Intel Cadre 1st Gen i5 Processor
    90W Power supply - Former 6 Cell Lion Battery

Known Issue with the Laptop:
Battery is Dead, but plugged in. It does not accuse and is 4 years sometime.

The Trouble
I ability on the laptop --> It starts to boot upward --> CPU fan is spinning --> Windows is starting screen --> And about twenty seconds into this --> Fan speed picks up --> I hear a click and the laptop powers down

Hither are the things I know:


    There is no Mail consequence (sound) --> kick happens
    Not an issue with HDD --> The power down happens even if I get into BIOS and stay at that place for 20 seconds
    Most probably non an effect of over-heating -- 20 seconds seems like an awfully brief fourth dimension, only I may exist incorrect

Things I've tried


    Removing the RAM sticks and booting --> when I do this the laptop DOES NOT power off. It stays on the Post mistake indefinitely --> Which is surprising
    Removing Battery and booting but on Air-conditioning power --> Same issue
    Removing HDD and booting --> This brings upwards the "Select a BOOT device" screen -- > Even from this screen the laptop powers down.
    Trying either RAM stick independently --> Highly unlikely that its a RAM upshot
    Reapplying the thermal paste - I've done this equally well - no help. One caveat here - The paste I am using may be the trouble, its called HT-GY260 - http://world wide web.amazon.com/Flashlight-Thermal-Grease-Silver-HT-GY260/dp/B00W8AJRV8. Let me know if any of you know that this is an issue.

My theories are as follows:
1. Motherboard Issue --> Although I hope this is not the instance, it does seem highly likely
2. Battery issue --> Does non make much sense, merely could it be that a faulty bombardment can crusade the laptop to spontaneously ability down?
3. CMOS effect? --> This is rather hopeful, merely can a expressionless CMOS battery cause this behavior.

Update:


  • Something I just observed - In that location'due south a distinct click sound when it powers downward

I welcome any other diagnostic ideas!

Appreciate the help.

Depending on how easy it is to do this I would try detaching everything unnecessary and seeing if you still get the aforementioned result. (Fleck harder to practice on laptop than a desktop)

Simply just go out Mobo, CPU, 1 Stick of Ram and Power string connected, then take out other ram, disconnect hard drive, usb devices etc and run across if it keeps power and so. If not see if you can get your hands on an alternative ability supply and effort that. This does non look good though :(

Unplug from mains, hold power push down for 20 seconds. Plug back in and turn it on.

Have you lot tried resetting the CMOS? It's worth a endeavor at this stage I gauge.

Thank you for you response. 2 quick questions:
1. What am I looking for when I practice the unplug --> hold --> ability.
2. How does one go virtually resetting the CMOS? Is it simply pull it out and put it back in? Should I consider replacing it?

It removes the power from all components, just the affect of this is that the software interfaces betwixt the BIOS and the hardware are severed and so the BIOS reestablishes those software interfaces between the BIOS and hardware when the reckoner is reconnected to power. This is coupled with the clearing of the estimator's temporary memory. That way, if i of the software interfaces between the BIOS and hardware is malfunctioning, it is reset.

You lot should just be able to remove the cmos leave it out for five minutes and put it back in. Try this pick second though.

Tried your proffer - unplugged from mains, removed battery (is this okay?) and held power downwards for 20+ seconds - zip conspicuous happened, I did not go a screen or a message or a beep when I held the power push down for 20 seconds. The ability down issue remains despite this :(

Depending on how easy information technology is to do this I would try detaching everything unnecessary and seeing if you still get the same effect. (Bit harder to do on laptop than a desktop)

Just just exit Mobo, CPU, ane Stick of Ram and Ability cord connected, so take out other ram, disconnect difficult bulldoze, usb devices etc and see if it keeps power then. If non run into if you can get your easily on an alternative power supply and endeavor that. This does not look good though :(

Depending on how like shooting fish in a barrel information technology is to exercise this I would try detaching everything unnecessary and seeing if you lot still get the aforementioned upshot. (Flake harder to do on laptop than a desktop)

But just exit Mobo, CPU, one Stick of Ram and Power cord connected, and so have out other ram, disconnect hard drive, usb devices etc and see if it keeps power then. If not see if you lot can get your easily on an alternative power supply and endeavour that. This does not wait good though :(

Did that, aforementioned issue - I'm guessing its the Mobo. I'grand salvaging the HDD and RAM, scrapping the residuum. Thanks for your suggestions :)

this seems to be a problem with people non asking how old the laptop is or how oftentimes its used but logic to me says to check out the powerboard containing your ability push button the contacts on this button could exist stuck on one side thus making your laptop think you lot are belongings the button downwards you tin try replacing this lath at your own risk but i would let a tech deal with that the other side of information technology is that you should test the electric current coming from your battery and from your air-conditioning adapter to brand sure you are getting the proper and steady flow of power

I had the same exact trouble with my laptop.it would turn on for i min then shut off.diagnostics said cpu thermistor 103c.it was over heating.turns out i didnt have anymore paste/chemical compound/heat sink left underneath my cpu.i replaced it with more,nail,problem solved! Hasnt close off on me since (knock on wood)
