Update = Resolved After completing troubleshooting, a DELL-Cares agent setup a part replacement.
I have an Inspiron 5402/5409 and suddenly there is no response when I try to power it up; the white charging light on the laptop also doesn’t light up but I do see the green light on the AC adaptor. I tried all diagnostics test like holding the power button for 20-30 sec with the laptop plugged in and not plugged in, etc. I had this issue a month ago but when the service tech came by it powered on for him and he said I just had low battery and his tests say that all hardwares are fine. But I don’t understand because I kept the laptop plugged in the whole time and even tried different outlets around the house. Could this be a motherboard issue? Even before it became unresponsive a month ago my laptop would randomly restart after it’s been in sleep mode
Laptop is unresponsive
