My laptop just shut off and absolute wont turn back on.

@evxnppg it sounds to me like you are saying your computer does no longer turn on. Even with a power supply. In that case start off with the easy things.

Disconnect the power from the computer by unplugging the power cord from your computer. Disconnect all external devices from the computer. Remove the battery Now hold the power button depressed for about 30sec-1min. Reapply the AC power adapter and see if your computer does show any sign of life.

Next you want to check your power supply. Make sure it has all the proper voltages. Check to make sure the connectors are not bend etc. After that, check the charging port. Clean it of any debris etc, use a few puffs of air to clean it out. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. If none of this works, get a ammeter and see if your laptop draws any amperage from the charger.

After that, you need to check and see if your motherboard even gets power. For that of course, you need to open it up. Post Some good pictures of what you see. That way we can see what you see Bilder zu einer vorhandenen Frage hinzufügen

Once we have more detail from you, we can always go into more specifics as needed.
