My laptop is still currently having this same issue. I've tried everything and anything. Unfortunately I've resulted into seeking other gaming PC that are not Dell. I've had this brand new Alienware Laptop for less than 3 years, as much as I would like to think this will be resolved by Dell, it never will. That's not how their customer service works. I appreciate your time and efforts, they were not in vein but I think the real solution here, is to not own an Alienware or Dell product.
I'm so sorry you've gone through all that. It does not give me hope for this issue though. I've loved this laptop, and it saddens me to have to seek other gaming PCs but, I never want to have to run into this again.
No I have not. But I already spent a lot of money on this laptop, I don't feel like chasing "what if" options and spending more money along the way. I feel like if anything, this is an KNOWN issue with a lot of laptop currently and Dell should own up to it. They should hold themselves accountable and fix it.
The multimeter checks if the output voltage and current of the power adapter match the marked ones.
If the gap is very large, or there is no output voltage, and the voltage is normal, you can judge that the power adapter is faulty.
The notebook power adapter needs to be replaced.
If the above checks are normal, remove the laptop battery and do not connect the adapter.
Press and hold the notebook power button for 5 seconds to repeat 3 times. After releasing the residual charge of the notebook,
Insert the power adapter separately, power on the test and check the power interface of the notebook.
For example, loose or damaged appearance.
If the above checks are normal, basically it can be judged that the notebook motherboard is faulty. It is recommended to send the service station.
Alienware M17X R4 plugged in not charging - power supply not recognized
I noticed that some time ago that Alienware-Naomi was helping a guy out with similar issues to my laptop.
Of particular significance was her saying "BIOS A13 is for Windows 8.1 and BIOS A12 is for Windows 7 and Windows 8"'.
Mine is on A12 but I've recently upgraded to Windows 10. I have A13, A14 and A15 BIOSs downloaded but I can't flash those because i get a warning saying that I must have a battery installed and charger working to flash the BIOS!!
Am I expected to go back to Windows 7, flash the A13, A14 or A15 BIOS then upgrade to windows 10 again???
Please offer me some help!!
