When choosing a power supply for a laptop with 65W instead of 90W, it's important to ensure that the voltage and polarity of the new power supply match the requirements of the laptop. Additionally, the new power supply should have a compatible connector to the laptop's power input. It's also important to consider the charging time and performance of the laptop with the lower wattage power supply. It's recommended to consult the laptop's manufacturer or a certified technician to ensure compatibility and safety. **

For two 5V 90W LED strips, you would need a power supply that can provide a total of 180W (90W per strip). Since the LED strips operate at 5V, you would need a power supply that can deliver at least 36A (180W / 5V = 36A). It is important to choose a power supply that can handle the total power requirements of both LED strips to ensure they operate properly and safely. **

For two 5V 90W LED strips, you will need a power supply that can provide at least 180W of power in total. Make sure the power supply is rated for 5V output to match the LED strips' voltage requirement. Additionally, ensure that the power supply has enough current capacity to handle the combined load of both LED strips, typically around 36A (180W / 5V = 36A). It is recommended to use a power supply with a slightly higher wattage rating to ensure stable and reliable performance. **

The cable of the 90W power supply should be at least 2 meters long if there is a demand of 180W. This is because the cable needs to be able to handle the higher power demand without overheating or causing a voltage drop. A longer cable also allows for more flexibility in positioning the power supply in relation to the device it is powering. **

The laptop may not be booting up due to a variety of reasons. It could be a hardware issue such as a faulty power supply, a damaged motherboard, or a malfunctioning hard drive. Alternatively, it could be a software issue such as a corrupted operating system or a virus. It's also possible that the laptop's battery is completely drained or the power button is not functioning properly. Troubleshooting the specific issue will require further investigation and potentially professional assistance. **

To connect your MacBook Air 2022 to an external monitor with 90W power delivery via USB-C/Thunderbolt, you can use a USB-C/Thunderbolt to HDMI or DisplayPort adapter or cable. Simply connect one end of the adapter or cable to the USB-C/Thunderbolt port on your MacBook Air and the other end to the HDMI or DisplayPort input on the external monitor. Make sure the adapter or cable supports power delivery of at least 90W to ensure your MacBook Air can charge while connected to the monitor. Once connected, your MacBook Air should automatically detect the external monitor and you can adjust the display settings in the System Preferences to extend or mirror your desktop. **

My laptop boots up to the logo of the manufacturer, which is Dell. The Dell logo appears on the screen when I turn on my laptop. This logo is displayed briefly before the operating system starts loading. **
