My MacBook air m2 is charging but not powering on. I shut it down and connected it to the charger till the Magsafe turned green then disconnected, but won't power on.

Leave the power adapter connected until the laptop is able to power on. These USB-C Macs many times will not power on without the power adapter being connected.

When you connect the power adapter, do you hear the "ding" (sometime shortly after making the connection)?

Please help

I have tried pressing the power button for 15-20 seconds and also charging with a usb type c charger

Holding the power button down for 10 seconds will force the laptop to power off. So you must release the power button, wait a few seconds, then press the power button (or any key actually) to try & power it on. Pay very close attention to the display to see whether you may notice any slight flash or flicker, or a faint lightening of the black which indicates the backlight is on & the laptop is actually powered on.

Wait at least 30 seconds to a minute and try pressing the Caps Lock key to see if it lights up which also indicates the laptop has powered on & may even have booted into some mode (perhaps at login screen, or maybe a recovery mode/assistant screen. I would actually try a force power off (holding power button for 10 seconds) & attempt a power on and wait a bit longer just to be sure since timing is everything when trying this Caps Lock key test.

Definitely follow the troubleshooting tips in the Apple article @D.I. Johnson linked. Within that Apple article is the following article which has as its last step a DFU Firmware Revive which unfortunately requires access to another Mac currently running macOS 15.7+ Sequoia or macOS 26.x Tahoe (the former requires using Apple Configurator while the latter can use it as well or the Finder). The reason I am mentioning this here now is that the Apple Configurator app on a host Mac with your laptop connected to it with a USB cable to your laptop's DFU Port can give you a tiny little bit of feedback on the state of your laptop....it isn't much, but at least you will know if the laptop is powered on or in DFU Mode.

Am using a mag safe charger and it turns orange then green after a while. I've tried pressing the power button as you've instructed but still no change. There's no keyboard light or apple chime on powering on or connecting the charger

Try using a USB-C charging cable instead to see if that will make any difference. Pay attention to whether you hear a "ding" sound within a few minutes of connecting it.

Make sure to disconnect all external devices just in case one of them is causing a problem.

It sounds like you've taken some of the basic troubleshooting steps.

This is Apple's guidance for a Mac that doesn't turn on:

If your Mac doesn't turn on - Apple Support

At the bottom of that document is this - ❝If your Mac still doesn’t turn on, it might need service.❞ - and a link to Get Service.

A pretty unlikely idea:

Are you sure the Mac isn't coming on? I've been fooled when the display is just turned down.

It's a shame it doesn't have one of those little holes you stick a paperclip in. (Am I too old?)
