Safety information
- Lithium-ion batteries can overheat if damaged. Do not puncture, crush or expose the device to high heat (for example, a closed car in summer). Stop using it and contact service if the case bulges, the battery swells or you notice a burning smell.
- Use the computer on a hard, flat surface. Do not block the vents with bedding, cushions or your lap for long periods; the underside can become hot enough to cause discomfort or burns.
- Use the 45 W power adapter supplied with the computer, or a replacement from the manufacturer with the same voltage and an equal or higher wattage rating. Inspect the cord regularly and replace it if the insulation is damaged.
- Keep liquids away from the keyboard and vents. If liquid is spilled, shut down immediately, unplug the power and let the computer dry completely before restarting.
Setup
- Unpack and inspect
Remove all packaging, protective film and cardboard inserts. Keep the box and receipt until you are sure the tablet works correctly.
- Connect power
Plug in the 45 W adapter before first start-up; the battery may ship with a low charge. You can use the tablet while it charges.
- Complete operating system setup
Follow the Windows setup screens to choose your region, connect to Wi-Fi and sign in. Then open Settings > Windows Update and install all available updates, including optional driver and firmware updates.
- Update firmware and drivers
Use the manufacturer's update utility or support page to install the latest BIOS/UEFI firmware and chipset drivers. Keep the computer plugged in during firmware updates.
- Set up backups
Turn on cloud sync or connect an external drive and schedule automatic backups before you store important files on the computer.
Using your tablet
Sleep and power settings
As shipped, the Zebra ET80A turns off its display after 5 minutes of inactivity and goes to sleep after 20 minutes. Keeping these timers short is the easiest way to save energy. Its default low-power state is an alternative low power mode (ALPM), a reduced-power idle state used in place of conventional sleep; it resumes almost instantly.
Battery care
The battery stores 40 Wh. At the measured idle draw of 5.8 W that is a theoretical ceiling of about 7 hours with the screen on and nothing running; real-world runtime with browsing, video or calls is shorter.
- If the manufacturer's software offers a charge limit (often 80%), enable it when the computer stays plugged in most of the time.
- Avoid leaving the computer in hot places; heat is the main cause of permanent battery capacity loss.
- For storage longer than a month, charge to about 50%, shut down fully and keep it in a cool, dry place.
- Use the operating system's battery-saver or efficiency mode when you are away from an outlet.
Performance
With 16 GB of memory, the system handles typical office multitasking, browsing with many tabs and light creative work comfortably. Solid-state storage needs no defragmenting; leave 10–20% of the drive free so it can maintain performance.
Care and maintenance
| When | What to do |
|---|---|
| Weekly | Restart the tablet to apply pending updates and clear memory; confirm that backups completed. |
| Monthly | Install operating system and application updates. Wipe the screen and case with a soft, slightly damp microfiber cloth (power off first). |
| Every 3–6 months | Inspect the charging port and gently remove lint with a dry, soft brush or wooden toothpick; check the case and screen protector for cracks. |
| Every 6–12 months | Check for BIOS/UEFI firmware updates from the manufacturer and review storage health and free space. |
| Yearly | Check battery health in the operating system or manufacturer's utility; replace the battery through an authorized service provider if capacity has dropped significantly or the case is bulging. |
Troubleshooting
Start with the simple checks below. For error messages specific to this model, use the manufacturer's built-in diagnostics and support documentation.
| Problem | Possible cause | What to try |
|---|---|---|
| Will not turn on | Depleted battery; charger not connected or faulty. | Connect the charger and wait 15–30 minutes, then hold the power button for 15 seconds and try again. |
| Runs hot | Heavy app or game; charging in a hot place or inside a thick case. | Close demanding apps, remove the case while charging, and check Task Manager for apps using a lot of power. |
| Slow performance | Too many background apps; storage nearly full; pending updates. | Close or disable unneeded startup items, free up storage space, install updates and restart. |
| Will not wake from sleep | Software or firmware issue; accessory preventing wake. | Press the power button briefly; update chipset, graphics and firmware; disconnect USB devices to test. |
| Wi-Fi drops or is slow | Weak signal; outdated software; router issue. | Move closer to the router, update the network driver, and restart the router. |
| Battery not charging | Adapter underpowered or damaged; charge limit enabled; battery worn. | Use the original 45 W adapter, check the charge-limit setting, and run the manufacturer's battery diagnostic. |
Energy use and running costs
The Zebra ET80A has a typical energy consumption (TEC) of 16.7 kWh per year, about $2.84 a year at $0.17 per kWh. TEC combines the measured off, sleep and idle power with ENERGY STAR's standard assumptions about how many hours a year a tablet spends in each state. It does not include time under heavy load such as gaming, rendering or video export, which can draw several times the idle figure.
| Power state | Measured power |
|---|---|
| Short idle (on, screen on, nothing running) | 5.8 W |
| Long idle (display off) | 0 W |
| Off (plugged in) | 0.3 W |
