I just bought a new Dell Inspiron 1545, and I have plugged in the AC adapter to charge it for 12 hours. However, there is no light on the laptop itself to indicate it is charging, only a steady blue light on the adapter. Does this mean the laptop is in fact charging?
2 ways to check
Control Panel under power options
In the BIOS, F2 at boot, the battery charge status should be shown there
Inspiron E1505 Windows 10 / XPS 10 Windows RT
Dimension 8400 Windows 7/8
Put your cursor over bottom right over battery icon and it will tell you if its charging also plug icon on battery.
