If your laptop is not booting, there are a few steps you can take to try and resolve the issue. The first step is to check the power sources of your laptop. Ensure that the power cable is connected properly and securely, the outlet you are using is working, and that the battery is charged. If the power sources of your laptop check out, move on to the next step in troubleshooting.
The next step is to examine the inside of your laptop for any signs of dust, dirt, or debris. Make sure to use compressed air with an anti-static brush to safely remove any dust and debris. Afterward, make sure to reconnect all cables and check that the internal components such as RAM, GPU, and CPU are seated properly.
Next, examine the outside of your laptop for damage. Check the ports, USBs, and audio jacks for signs of physical damage. If any of these ports are damaged, you will need to replace them in order to get your laptop up and running again. Furthermore, if you have a laptop with an external graphics card, make sure to check for any damage to the connectors. If any damage is found, you will need to replace the graphics card or repair the connectors.
Once you have examined the power sources, the inside, and the outside of your laptop, it is time to turn it on. If the laptop still does not boot up, you will need to perform a Hard Reset. A hard reset consists of removing the battery from the laptop and holding down the power button for 30 seconds. After this, insert the battery back into the laptop and attempt to boot it up again. If this fails, you may need to open up the laptop and examine the motherboard for any signs of damage or corrosion.
If the motherboard looks okay, you may want to remove the RAM and reinsert it. This can sometimes fix a hardware issue that is preventing the laptop from booting up. If there is no improvement after doing this, you may want to consider resetting the BIOS. Resetting the BIOS can be done by pressing a particular key combination when turning the laptop on. It is important to note that each manufacturer has its own key for BIOS reset, so you will need to seek out the instructions for your specific laptop model.
At this point, if none of the troubleshooting steps have worked, you will likely need to consult with a qualified technician who can further investigate the issue. While diagnosing a technical problem can be difficult, following these steps will give you a better chance at finding and resolving the root cause of the problem.
Finally, if none of the steps above have resolved the issue, it might be time to consider getting a new laptop. While getting a new one can be costly, it is often a more cost-effective and reliable approach in the long run.
