The other night I was on my laptop (Gateway NV57H20u) playing a game and it was about to die so I plugged in the charger and it shut off shortly after. The laptop was working completely fine before hand and now it won't even turn on. There are also no lights on when I've got it plugged into the charger like there usually are when charging.

I've tried unplugging the power supply and taking the battery out and holding the power button for 30 seconds and then plugging in the power supply and battery. I've also tried just letting it sit to see if it would hold a charge and nothing happened.

Any help would be appreciated!

Thread summary: ’s Gateway NV57H20u went dead while plugged in and now shows no LEDs. correctly suggested checking the adapter and suggested running on AC with the battery removed. Because a known-good charger and battery removal were already tried, the next steps should focus on the laptop’s input and power circuitry rather than repeating those basic checks.

Recommended diagnostic sequence (low-cost → higher-effort):

  • Verify the adapter’s actual output with a multimeter against the rating printed on the adapter. If the measured voltage is absent or well below the label, replace the adapter or have it tested elsewhere.
  • Inspect the adapter cable and barrel tip for broken wires or a split insulation near the strain relief; flex the cable while watching the adapter/laptop LEDs for flicker. A lit charger LED doesn’t guarantee the tip is delivering voltage under load.
  • Examine the DC jack and harness: a loose/bent jack or a cracked solder joint where the jack mounts to the board is a common failure. With battery removed and AC unplugged, open the case (if comfortable) and look for a separate jack board or damaged solder joints.
  • Look for visible motherboard damage (burn marks, bulging capacitors) near the power input. Any visible damage points toward board-level repair.
  • If comfortable using a meter, check whether the adapter voltage appears at the board-side connector. If voltage reaches the board but nothing powers up, the internal fuse/regulator/MOSFETs may have failed.
  • As a low-effort try, reseat memory and unplug nonessential drives—unlikely to fix a no-power, no-LED fault but helpful before escalating.

Safety and next steps: always remove AC and battery and discharge static before opening the case. If unfamiliar with electronics work, gather diagnostics first (adapter model and rated output, measured voltages, battery voltage, photos of the jack/board) and take the machine to a reputable repair shop — most shops can replace a DC jack or diagnose a motherboard power failure.

Hello,

I would say check your charger or if anybody you know has a gateway with the same charger try it on your laptop. Most chargers have a light on the charger that shows they are working and a light on the laptop that shows they are charging. If the charger is on and someone elses charger will not charge your laptop then you will need to take it in and have the charger port checked. They get broken a lot when people hit the plug in the side of the computer when they are plugged in.

I tried it with another charger that I know works and no luck. I was literally sitting still on the couch when it turned off, and it was charging fine before it turned off. Once it turned off, it was just dead and wouldn't charge or anything.

Try taking out the battery, and try to use the computer on the power cord only.

I've tried that aswell
