To force your HP laptop to start up, you can try the following troubleshooting steps:
1. Check the power source: Ensure that your laptop is plugged into a working power outlet and the power adapter is properly connected. If your battery is completely drained, it may take a few minutes for the laptop to respond.
2. Remove external devices: Disconnect any external devices such as USB drives, printers, or docking stations. Sometimes, a faulty external device can cause the laptop to hang during startup.
3. Hard reset: Unplug the power adapter and remove the battery (if it's removable). Press and hold the power button for 15-20 seconds. Then, release the power button, reconnect the battery (if applicable), and plug in the power adapter. Try starting the laptop again.
4. RAM reseating: Open the access panel on the bottom of your laptop and locate the memory (RAM) modules. Carefully remove the modules, clean the contacts with a soft cloth, and reinsert them firmly. This may help resolve startup issues caused by faulty RAM.
5. Check for hardware issues: If the above steps didn't work, there might be a hardware problem. Consider seeking professional help or contacting HP support for assistance.
Note: The steps may vary slightly depending on your laptop model and operating system, so it's always helpful to refer to the user manual or HP support documentation specific to your device.

There could be several reasons why your HP laptop is not starting. Here are some common ones:
1. Power issues: Make sure that your laptop is properly charged or plugged in. Check the power adapter and try a different power outlet or charger to rule out any issues related to power supply.
2. Hardware problems: The laptop's hardware components may be causing the issue. It could be a faulty battery, a damaged power button, or a malfunctioning motherboard. In such cases, it is advisable to seek professional help or contact HP support for assistance.
3. Software issues: Sometimes, software or driver problems can prevent the laptop from starting. Try performing a hard reset by removing the battery and AC adapter, holding down the power button for around 15 seconds, then reconnecting them and turning on the laptop. If that doesn't work, you can try booting into safe mode or performing a system restore.
4. Display problems: If the laptop seems unresponsive, it could be a problem with the display. Connect an external monitor to check if the display is working properly. If it works, the issue may lie with the laptop screen itself, and it might need to be replaced.
If none of these troubleshooting steps resolve the issue, it is recommended to contact HP support or take the laptop to a professional technician for further diagnosis and repair.

The power button on most HP laptops is typically located on the top row of the keyboard, usually on the right-hand side. It is usually represented by a circular or rectangular icon with a line inside it, or it may have the word "power" written next to it.
