I have dell inspiron 15 laptop 3521, facing power on problem. So how do i fix it. When i called customer care then they are suggesting to change the motherboard that will cost 15000rs and only 3 months warranty. So please help me to fix my laptop myself only.
1. Unplug your charger cord.
2. Remove the battery.
3. Press and hold the "Power" button for 30 seconds.
4. Now plug back in the power/charger cord.
5. Now put the battery back in.
If this doesn't help, then test the power cord to see if it is good. Either try your cord in another device, or try another devices cord in your laptop. You may also want to try charging it when the device is off, rather than on. If it works then, the cord is probably the issue.
Should that not be the problem, then check the battery to see if it needs replacing.
