Most common issues can be solved one of these ways.
1) Turn your computer completely off, let it sit off for 30 seconds, turn it back on. This fixes lots of common software issues.
2) Internet problem? Go to your router (should be where your cable provider has a coaxial cable coming into a square upright/horizontal box or the device next to it), unplug it, let it sit for 10 seconds, plug it back in, try reconnecting to the internet. It still amazes me how many issues can be solved doing this simple step.
3) Laptop won’t boot up (turn on)? Remove the battery from your laptop, plug the laptop in (with the battery still removed) using the AC charger that you use to charge the laptop. Press the power button. If it fully boots up, the issue is likely a battery problem. If however, the laptop doesn’t turn on with the battery removed while plugged in, it’s likely an issue with your DC charging station connector inside the laptop or a motherboard issue itself and will require service. Lastly, check to make sure the light on your power cord is green, not orange or red. If it’s orange or red, the issue could be with the power cord itself not the laptop.
Hopefully, one of these solved your problem and you’ve saved a bit of cash in the process.
