No Power?
First - Make sure the device has power. If the device runs off batteries, make sure the battery has a charge or plug it into AC power if possible. If the device runs on AC, check for a firm power cord connection and confirm the outlet works. If the workstation uses a power strip, surge protector, UPS, or the like, make sure it isn’t switched off and confirm the device itself is connected.
In the case of a Laptop Computer that refuses to start up, consider removing the battery and plugging the device in using the supplied power cable. You might need to press and hold the power button for up to 30 seconds. After releasing the power button, press it normally to see whether it starts up.
Some PC’s fail to come out of Sleep/Hibernate mode and get stuck there, so they seem completely dead. Hold down the Power Button for 5 to 10 seconds and then release it and press it again.
If it’s a Handheld/Smartphone Mobile device, try a Soft Reset first, if that doesn’t work try a Hard Reset.
Won’t Start Up Normally?
What has changed? Did you install any new hardware or software? Has the computer been moved? Did the OS restart itself after installing an update?
System Restore?
A feature to revert to a previous day’s restore point. Using a restore point will not cause you to lose any recent data file edits. Here’s how in Windows 10:
- Right-Click the Start Button and Click System
- Click System Protection
- Click System Restore
- Click Next
- Select a Restore Point - If you have a choice, pick the one immediately before the problem started.
- Follow the prompts to complete the restoration of the system files to that point in time.
System Restore is completely reversible, just run it again and follow the prompts to undo the restoration.
