Running a laptop repair service, & having all laptop brands for repair day by day helped me to classify most current laptop problems brand by brand. For DELL laptops the most general problems that we are facing power issues, especially power jack issues. The symptoms are: the laptop is operating on battery only, has no power, or will not charge the battery. We support a full jack replacement, not only fasten the pins of the power jack on the motherboard as they will abandon again as they did it the first time. A power jack replacement will protect you from changing the motherboard, and the cost is around half than the motherboard replacement. The only problem is that Dell laptops, after a power jack or a motherboard replacement have the tendency to not recognize the AC-DC adapter or the battery.
This is appearing regularly on Dell laptop, but we found a fix that worked in most of the cases. After you replaced the Dell power jack or Dell motherboard, before starting the laptop remove the CMOS battery for 5 min for BIOS reset. You will require a dell compatible AC-DC charger and a dell compatible battery charged above 10%. Press F2 key, it will take you to the BIOS setup. In setup set the clock. Restart saving the changes. When the new BIOS message appears press F1 key to continue. When in Windows go on the DELL website, search for your model drivers, and download the BIOS upgrade. Work DELL BIOS upgrade, and the system will reboot & upgrade the BIOS. When started again, your laptop will probably appreciate the battery and AC-DC adapter.
If the Dell laptop system will not recognize the battery or the charger pin next these steps, then your parts are broken.
You can simply check the battery by pressing the battery state button located on the end of the battery. If the battery is good it will light green showing the amount of charge. If nothing seems, that means that your battery had its days and need to be replaced.
The AC adapter can be checked with a voltmeter, or if the laptop it is working on battery but not on AC adapter try another one if you have one.
