Laptop will not charge. What's happened up to this point:

  • Battery stopped being detected by the computer. Charger was still working at this point; I could use the computer without the battery if it's constantly plugged in.
  • Bought a new battery, same model as old
  • Inserted new battery, it charged fine, unplugged
  • Later when it needed to charge again the charger was not even detected.
  • Indicator light on the laptop won't go on, not detected by operating system (tried both ubuntu and windows)

The charger is quite expensive, and I'm hesitant to say for sure that it's the problem, because it seems weird that the charger would break just a few hours after the new battery was used. Is there any way to check whether the charger is working without buying a new one?

Laptop is an MSI, model MS-16F3

  • Does the charger itself have an indicator light? And yes these things can break batteries if they output the wrong voltages, so it is actually possible that the charger damaged the battery but now the charger simply died. – LPChip Jun 24 '18 at 20:04
  • @LPChip No, the charger does not have an indicator light. – Benjamin Sigal Jun 24 '18 at 20:13

    Then the only way to know if the charger is dead or not, is by checking it with a volt meter. See if it delivers the amount that is specified on the label. If its off by enough, even though it still supplies power, it will not be recognized by the laptop. – LPChip Jun 24 '18 at 20:18

    @LPChip, a voltmeter test is not enough to ensure the supply can provide the correct current, and that there is not excessive ripple. A better check would be to go to a store selling MSI products and try another charger (I'd be hesitant to borrow one from a friend, lest the laptop charging circuit cause PS failure). BTW, a replacement PS list on Amazon for ~US$40. – DrMoishe Pippik Jun 25 '18 at 0:11
