Back in Business: How to Enable Auto Power-On

By ·Categories: Tech Explained·Published On: February 5th, 2021·3 min read·

Did you know that you can set your computers to auto power-on after a power loss? At OnLogic we produce high-quality, rugged, fanless and ventless PC solutions designed to reduce failure points and ensure minimal downtime for our clients. Unreliable power is something that many industrial computer users face on a daily basis. An uninterruptible power supply (UPS), also known as a battery backup, can help and provide backup power when your regular power source fails or voltage drops to an unacceptable level. But sometimes a UPS only buys enough time for a safe, orderly shutdown of your computer.

Power Loss Happens – Thankfully, so can Auto Power-On

While UPS solutions and industrial grade components go a long way toward ensuring system longevity, there are still situations where power loss is inevitable. Extended outages, or applications where a UPS system can’t be installed, can lead to systems powering down. But what happens when power is restored and the hardware needs to be powered back on? Industrial and rugged PCs are often mounted in hard-to-reach, out-of-the-way places, where simply pressing the power button is either highly inconvenient or downright impossible.

In these situations, wouldn’t it be ideal if the computer just powered up on its own once power was restored? Thankfully, all OnLogic computers have this capability, and it’s just a setting away. Depending on the system, this setting can be enabled using hardware or software, but either way it’s easy and reliable.

Auto Power-On Using Hardware

Hardware options in the form of a motherboard pin header ensure that a dead CMOS battery or BIOS reset won’t affect the setting. The drawback can be that changing the appropriate jumper requires opening the case which can be challenging for fanless, ventless systems, so it’s ideal to add the jumper during assembly. Even then, support and functionality of this hardware method isn’t universal, so a software solution is frequently the more desirable choice.

You can test the hardware auto power-on function by shutting down your computer, then disconnecting the AC power adapter. Wait 1 minute, then reconnect the power adapter. Without pressing any buttons, the system will (almost magically) turn on.

Setting Up Auto Power-On Using Software

Some motherboard manufacturers prefer to offer the auto power-on feature through software the BIOS.  This method has the advantage of not requiring disassembly of the computer to enable. All OnLogic computers have the ability to set auto-power on using this method. It’s a simple process that we have outlined for all our units on our support site.

Once on the support site, select the line and then your system. You can also use the search bar. Once you have located your system, simply look for the Enable Auto Power On instructions. While you are there, browse around a bit, our support team has outlined many helpful tips and tricks – including pictures! 

Auto power-on is just one more way our systems can be set up and essentially forgotten thanks to their ease-of-use, ultra-reliability and diverse feature set. If you have questions about enabling auto power-on, or any of the features of our industrial hardware, don’t hesitate to reach out to our Solutions Specialists.

    If you are using time schedule auto power on, make sure to check the system time and correct it if it’s late.

    That’s a very good tip Djordje! It’s important to make sure the system time is correct if you plan on scheduling power cycle events.
