help my 2ds XL won't turn on

If your 2DS XL charges but won't turn on when you press the power button, there are a few things you can try to troubleshoot the issue:

1. Hold down the power button: Sometimes, holding down the power button for a longer period of time (around 10 seconds) can force a hard reset and get the system to turn on.
2. Check the battery: Even though you've tried with another 3DS, it's still worth checking the battery on your 2DS XL. Remove the battery and check for any signs of damage or swelling. If the battery is damaged or swollen, it could be causing the issue.
3. Check the SD card: If the SD card is corrupted or damaged, it can prevent the system from booting up. Try removing the SD card and see if the system turns on without it.
4. Try a different power source: If you're using a power adapter, try plugging it into a different outlet or using a different adapter to see if that resolves the issue.
5. Contact Nintendo support: If none of the above solutions work, it's possible that there's a hardware issue with the system. You can contact Nintendo support for further assistance or to arrange a repair.
