The Micron RAM module might be bad. Since 4GB DDR4 modules are fairly inexpensive, I suggest that you try a new replacement module such as the Kingston in this link https://www.lazada.com.ph/products/kingston-valueram-4gb-2400mhz-ddr4-cl17-sodimm-laptop-memory-kvr24s17s64-i160522440-s195798045.html?spm=a2o4l.searchlistcategory.list.6.20fc644ayS5oVv&search=1 I cannot guarantee it will solve the problem but the tests you've done so far point to a bad RAM module.Jack E/NJ
(1) Is the battery charging with the charger plugged in --- a steady blue or amber LED lit?(2) When did this start to happen? Jack E/NJ
Have you tried to reset the system yet via the battery reset pinhole on the bottom? Jack E/NJ
OK. Try this. Go to the elevated command prompt. Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Compare design capacity with full charge capacity history. Post screenshot if possible. Jack E/NJ
Then you must disconnect the battery from the mainboard by removing the bottom cover to see if the laptop will stay on with the charger alone. Jack E/NJ
On the charger alone, what happens when the ALT+F10 keys are pressed IMMEDIATELY after pushing the power button? Jack E/NJ
OK. What happens if you instead press/tap the F2 key IMMEDIATELY after pushing the power button? Jack E/NJ
Good. Go to the BIOS menu Main tab. Make sure both F12 and D2D options are enabled. Then save setting and exit the BIOS. Shut machine off and retry the ALT+F10 procedure again as explained above. A recovery screen should appear that should allow you to reset the machine to factory condition shown in the video below. Jack E/NJ
>>>The battery is charging with amber light and goes into blue light which i think it means that the battery is full>>>When steady blue, remove the charger. Turn it on. Does it still shut off on the fully charged battery alone? Jack E/NJ
When the machine shuts off, can you IMMEDIATELY turn it back on again by pressing the power button? Or do you have to wait a few moments before it responds to pressing the power button? Jack E/NJ
