My adoopter doesn't supply the power

@palashmolla you are not giving us enough information. We will need to know if you actually checked the AC adapter or if you are having trouble with your HP laptop turning on. We will also need to know the exact model number for your computer.

First you want to check your power supply. Make sure it has the proper voltages (Output: 5.23V3A 15W USB-C) Check to make sure that connectors are not bend etc. Check the DC-in jack of your laptop. Make sure there is no corrosion, debris etc. that prevents it from working. Clean it of any debris etc., use a few puffs of air to clean it out. If your AC adapter does not provide the proper voltages you will need to replace the adapter

If none of this works, get an 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
