Have you experienced work, data, or hardware losses due to power outages? Acquire an uninterruptible power supply (UPS) to ensure your computer remains operational during brownouts and blackouts, or safely shuts down when power is interrupted.
Steps
Seek out an uninterruptible power supply.
- Most UPS packages provide information on what they can support and for how long. Having at least 15 minutes allows for safe document closure and shutdown, while an hour provides extra time to complete tasks.
- Printers and amplified speakers are non-critical devices.
- A modem or router powering the computer may be crucial for internet connectivity.
Take the UPS out of its packaging.
Follow the provided instructions.
Even if you don't use a phone line modem, utilize the phone filter if there's a phone on your desk. It could prevent electrocution in the event of a lightning strike.
Connect the monitoring cable (usually USB nowadays) and install the accompanying software.
Configure the software to initiate a safe shutdown or hibernation of the computer during power outages, especially when you're away or asleep.
After a few hours of charging, the UPS battery will be fully charged, ensuring your system remains operational during brief blackouts, or gracefully shuts down in case of power interruptions.
Helpful Tips
-
'Stand By' mode can conserve UPS power, but if the UPS depletes its battery, you risk losing unsaved work.
-
'Hibernate' provides a faster shutdown option, preserving your work exactly as you left it and requiring less time to resume.
-
All notebook PCs come with a built-in battery acting as a UPS. However, they lack surge protection on their AC power input unless provided separately.
Important Warnings
- Do not store a UPS. If not in use, consider selling it, giving it to someone, or repurposing it (e.g., as a backup for an answering machine). The sealed lead acid (SLA) batteries can degrade if not kept charged.
- Ensure proper recycling of dead UPS batteries.
- Devices connected to the computer that are not protected by the UPS battery should be plugged into surge-protected outlets. Unprotected circuits can pose a risk in the event of lightning strikes or accidents involving high-tension cables.
- Regularly test your UPS every few months by plugging in a 100-watt lamp to ensure it can sustain power for at least 30 minutes. This helps identify battery issues before they become critical.
