Restart vs Power-Cycle in a Dental Office: What to Try Before Calling IT (2026)
The schedule screen has frozen at the front desk, the card terminal says it cannot connect, and someone in the back is already reaching for the power strip under the server. "Turn it off and on again" is good advice for some machines in a dental office and a bad idea for others, and nobody has ever written down which is which.
Below are the steps for each, a device-by-device table of what staff may touch, and the point at which to stop and call. If the whole office has lost the internet, start with our guide to what to do when the dental office internet goes down instead.

What is the difference between restarting and power-cycling?
A restart is done from inside a computer's own software: it closes programs, shuts down Windows completely and starts it again. A power-cycle removes electrical power from a device that has no proper restart button, such as a printer, modem or card terminal, then restores it. Restart computers; power-cycle simple single-purpose devices.
| Restart | Power-cycle | |
|---|---|---|
| How | Start, Power, Restart (or the device's own restart option) | Switch off, unplug the power cord, wait about 30 seconds, plug back in |
| What it clears | Frozen programs, stuck print jobs, a Windows session that has run too long, pending updates | A device's memory and its connection to the network |
| Use it on | Front-desk and operatory computers, laptops, tablets | Printers, label printers, the internet provider's modem, a Wi-Fi access point with its own plug, card terminals |
| Do not use it on | The server or an imaging store without IT | Anything with a database open, the firewall, network switches, X-ray and CBCT units |
| Risk | Low, if work is saved and the dental software is closed first | Low on simple devices; real on anything that stores data |
The rule of thumb: the more other machines depend on a device, the less anyone but IT should cut its power.
Why does Shut down not fix what Restart fixes?
Since Windows 8, the normal Shut down uses a feature Microsoft calls fast startup. It closes your programs but saves the core of Windows, its drivers and services to disk and reloads them at the next start. A restart does not do that. So a computer shut down every night can still be running the same Windows session for weeks.
Microsoft's own documentation for hardware makers says so plainly: with fast startup, "the up-time between kernel reboots might be significantly longer than on previous versions of Windows because during user-initiated shutdowns, the kernel, drivers, and services are preserved and restored, not just restarted" (Microsoft Learn: fast startup). That is why IT asks "did you restart?" and means Restart, not Shut down and switch back on.
You can check for yourself. Open Task Manager (Ctrl + Shift + Esc), choose Performance, then CPU, and read the "Up time" figure. If it shows many days on a computer that "gets shut down every night," it has not had a full restart in that time.
How do you restart a front-desk or operatory computer properly?
Save your work, close the dental software completely, then choose Start, Power, Restart and let Windows finish any updates it starts. Sign back in, open the program, and test the exact task that failed. Restart once. If the same problem returns straight after a clean restart, stop and call IT rather than restarting again.
Restarting a workstation (3 to 10 minutes)
- 1Save and note the errorSave any open note, claim or document. Take a photo of the exact error message before it disappears.
- 2Close the dental software properlyExit Dentrix, Eaglesoft, Open Dental or the imaging program from its own menu, not by switching the computer off. On an operatory PC, never restart in the middle of an image capture.
- 3Choose RestartSelect Start, then the power icon, then Restart. Do not hold the power button unless the computer is completely unresponsive.
- 4Let updates finishIf Windows says it is working on updates, leave it. Switching off during an update is a common way to turn a small problem into a long one.
- 5Sign in and test the taskOpen the program and repeat the exact task that failed: the same patient, the same report, the same print.
- 6One restart onlyIf the problem is back after a clean restart, restarting again rarely helps. Note what happened and call IT.
One dental-specific warning about leaving computers on: Henry Schein One's Dentrix System Requirements 2026 say that "to avoid possible disconnect error messages on computers left inactive for long periods of time," offices should "disable the Power Management options on the network interface cards or close Dentrix when you are not actively using it." Closing the practice software at the end of the day and restarting regularly avoids a class of morning error messages. For imaging computers after Windows updates, see our guide to an X-ray sensor that stopped after a Windows update.
How do you power-cycle a printer, modem or card terminal safely?
Find the device's own power cord, switch it off if it has a switch, unplug the cord, wait about 30 seconds, plug it back in and wait until it is fully ready. Unplug only the power cord, never the network or USB cable. A modem can take several minutes to reconnect, so wait before you test.
Power-cycling one device (2 to 10 minutes)
- 1Identify the deviceMake sure you have the right box. Read its label. If you are not sure what it is, stop and ask IT before unplugging anything.
- 2Tell the officePower-cycling the modem drops the internet, the phones and the card terminals for everyone. Warn the front desk first.
- 3Unplug the power cord onlyLeave network and USB cables where they are. Unplugging the wrong cable is a common way to create a second fault.
- 4Wait about 30 secondsInternet providers publish slightly different waits; AT&T's gateway instructions, for example, say to wait 20 seconds before plugging back in.
- 5Plug it back in and waitGive it time. AT&T says its gateway "may take up to five minutes" to come back online. Printers and terminals are usually faster.
- 6Test one thingPrint one page, load one web page or run one card. If it works, you are done. If not, call IT and say what you power-cycled and when.
Do not confuse a power-cycle with a reset. The small recessed Reset button on a modem or printer usually restores factory settings and wipes its configuration, such as the Wi-Fi name and password or the printer's network address. AT&T's support page makes the same distinction (AT&T: restart or reset your gateway). A restart or power-cycle keeps the settings; a reset does not.
Some devices have no power cord of their own. Many Wi-Fi access points, desk phones and cameras get their power through the network cable from a switch in the closet. Those are IT's to restart, usually remotely.
Which devices in a dental office can staff restart, power-cycle or never touch?
Staff can restart their own computers and power-cycle simple single-purpose devices. Anything that stores the practice's data, protects the network or emits X-rays belongs to IT or the equipment vendor. Cutting power to a server or storage box while the database is open risks damaging it, and that damage can take far longer to fix.
| Device | Staff may | Why |
|---|---|---|
| Front-desk or operatory computer | Restart (once) | Clears most frozen programs; close the dental software first |
| Laptop or tablet | Restart | Same as a desktop |
| Printer, label printer, receipt printer | Power-cycle | No data stored; see our guide to a dental office printer not printing |
| Card terminal | Power-cycle, following the payment provider's instructions | Usually safe; the provider may have its own restart steps |
| Internet provider's modem or gateway | Power-cycle, after warning the office | Drops internet and phones for everyone while it restarts |
| Wi-Fi access point with its own plug | Power-cycle | Ceiling units powered by the network cable are IT's |
| Server | Never, unless IT asks you to and stays on the line | Holds the practice database and images; a hard power-off risks damage |
| Imaging store or network storage box | Never without IT | Same reason as the server |
| Firewall | Never without IT | Every connection in the office runs through it |
| Network switch | Never without IT | Everything cabled, including phones and access points, drops |
| Battery backup (UPS) | Never switch off | It is what keeps the server and network up in a power cut |
| Pano, CBCT or sensor interface box | Follow the imaging vendor's instructions only | Medical imaging equipment has its own start-up and safety steps |
| Phone system box in the closet | Never without IT or the phone provider | All lines drop |
Print this table, write each device's location next to it, and put it by the front desk. Labels on the devices themselves make it work: "Server: do not unplug" on the server saves more trouble than any training session.
In what order should you try things before calling IT?
Go up the ladder one step at a time and stop as soon as the problem clears: close and reopen the program, restart that computer once, check whether other computers have the same problem, power-cycle the one device involved, then call. If several computers fail at once, skip straight to calling IT.
- Close and reopen the program. Many freezes are one program, not the whole computer.
- Restart that computer once. Start, Power, Restart.
- Check another computer. If the same thing fails everywhere, the cause is shared: the server, the network or the internet. Do not restart every computer in turn; call IT.
- Power-cycle the single device involved, if it is one staff may touch: the printer, the card terminal or, after warning the office, the modem.
- Stop and call. If it still fails, or if the fix needs anything on the "never" list, call IT with what you tried and when.
Write each step down as you go. The note "restarted PC2 at 8:12, same error; printer power-cycled at 8:15, no change" saves the technician repeating your work. Our ticket checklist has a short template.
What should you not do?
Most damage from "turning it off and on again" comes from the wrong device, the wrong button or doing it over and over. Repeated hard power-offs, resets mistaken for restarts and unplugged network cables turn a five-minute problem into an afternoon.
Six things not to do
- Do not unplug, switch off or press the power button on the server or a storage box
- Do not press a Reset button thinking it is a restart: it can wipe the device's settings
- Do not restart over and over: one clean restart either helps or tells you to call
- Do not switch a computer off while Windows says it is working on updates
- Do not unplug network cables in the closet or behind devices to "reset" things
- Do not power-cycle the modem in the middle of card payments or a patient phone call without warning the office
When should you stop and call dental IT?
Call your IT provider when one clean restart does not fix a computer, when more than one computer or room has the same problem, when the fix involves the server, firewall, switch or imaging equipment, or when a device will not come back after a power-cycle. Call immediately if the schedule, charting, imaging or payments are down for the office.
Also call, without trying anything, if files have strange new names or will not open, or if a message on screen demands payment. Those are signs of a security problem, and restarting can make recovery harder. Leave the computer as it is and phone.
When you call, say what you restarted or power-cycled, at what time, and what happened afterwards. Mention whether other computers are affected. A good helpdesk can often restart the right service remotely without anyone touching a plug; that is one reason IT asks you to stop at the "never" list.
What to ask your IT provider about restarts
Ask these once and put the answers on the printed device table.
Routine
- Do our computers restart automatically after hours, and if not, should they?
- Is fast startup turned off on our workstations, or should staff always choose Restart?
The equipment
- Can you label the server, firewall, switch, modem and battery backup so staff know what not to touch?
- Which devices can you restart remotely, so we never need to touch them?
When something fails
- What is the first thing you want us to try, and at what point should we stop and call?
- Is the server on a battery backup that shuts it down cleanly in a power cut?
The contract
- If a hard power-off ever damages the server, is there a backup copy kept offline or air-gapped that a bad shutdown or ransomware cannot reach, and when was it last restored?
- When the fix is the imaging vendor's or the software vendor's, do you make that call as part of our monthly fee?
- Do we have a signed business associate agreement (BAA) with you for the remote sessions you use to restart our systems?

Frequently asked questions
What is the difference between a restart and a power-cycle?
A restart is done through a computer's own software: it closes programs and starts Windows again from scratch. A power-cycle cuts electrical power to a simple device, such as a printer, modem or card terminal, waits about 30 seconds and restores it. Restart computers and tablets; power-cycle single-purpose devices; leave servers, firewalls and switches to your IT provider.
Is shutting down the same as restarting?
No. With fast startup, the default shutdown since Windows 8, Shut down saves the core of Windows, its drivers and services, and reloads them next time. Microsoft notes that this preserves them "not just restarted." A restart clears them. When IT asks you to restart, choose Start, Power, Restart rather than shutting down and switching back on.
How long should I wait before plugging a device back in?
About 30 seconds is a sensible wait for printers, modems and card terminals. Internet providers vary: AT&T's gateway instructions say 20 seconds. After plugging back in, give the device time to start properly before testing. AT&T notes its gateway can take up to five minutes to come back online, and a modem tested too soon looks like it has failed.
Can I restart the dental office server myself?
Not unless your IT provider asks you to and talks you through it. The server holds the practice database and images, and other computers are connected to it all day. Restarting it the wrong way, or cutting its power, can interrupt work in every room and risks damaging the database. A good IT provider can usually restart server services remotely.
How often should front-desk computers be restarted?
A regular restart, such as once a week or after updates, prevents many slow-downs and odd errors. Many IT providers schedule restarts after hours so nobody has to remember. You can check how long a computer has gone without one in Task Manager, under Performance, CPU, Up time. Ask your IT provider what schedule suits your office.
Is it safe to power-cycle the internet modem during patient hours?
It is safe for the modem, but it drops the internet, cloud software, phones and card terminals for everyone while it restarts, which can take several minutes. Warn the front desk, finish any card payment in progress, and check whether the outage is the provider's before you unplug anything. Our internet outage guide covers those checks.
What if a device does not come back after a power-cycle?
Leave it plugged in and call your IT provider. Say which device, when you unplugged it and what its lights or screen show now. Do not press its Reset button or unplug it again and again. A device that does not return may have failed, may have lost power from another source, or may need IT to restart it remotely.
Why does IT always ask whether I restarted?
Because a restart clears frozen programs, stuck print jobs and a Windows session that has been running for days, and it takes a few minutes. It also tells the technician something: if the problem survives a clean restart, the cause is probably elsewhere, such as the network, the server or a driver. That is why a note of what you tried speeds up the fix.
The bottom line
Put a label on the server, firewall, switch, modem and battery backup, print the device table from this guide with each location filled in, and keep it at the front desk with the helpdesk number. Then the next "turn it off and on again" happens on the right box. If the same freezes keep coming back, a Free Dental IT Assessment looks at your computers, software, network security, backups and performance.
