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.
- Connect the computer to a grounded outlet, preferably through a surge protector. Replace a damaged power cord before further use.
- 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
Connect a compatible charger 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 on-screen setup to connect to Wi-Fi and sign in with your Google account, then check Settings for system 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
Set auto-lock (screen timeout) to a few minutes so the display turns off when the tablet is not in use; it sleeps automatically when locked.
Battery care
The battery stores 33 Wh. At the measured idle draw of 2.2 W that is a theoretical ceiling of about 15 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 12 GB of memory, close unused apps and browser tabs to keep the system responsive. 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 | Review free storage space and remove unused apps and large files; firmware updates arrive with the operating system updates. |
| Yearly | Check battery health in the operating system; 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 (or the restart combination in the manual) 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 the battery and app-usage screen in Settings for apps using a lot of power. |
| Slow performance | Too many background apps; storage nearly full; pending updates. | Close or disable unneeded apps, free up storage space, install updates and restart. |
| Will not wake from sleep | Software or firmware issue; accessory preventing wake. | Press the power button, connect the charger, and force-restart if needed; install the latest system update. |
| Wi-Fi drops or is slow | Weak signal; outdated software; router issue. | Move closer to the router, forget and rejoin the network, and restart the router. |
| Battery not charging | Adapter underpowered or damaged; charge limit enabled; battery worn. | Use the original adapter, check the charge-limit setting, and run the manufacturer's battery diagnostic. |
Energy use and running costs
The Lenovo TB710FU has a typical energy consumption (TEC) of 5.6 kWh per year, about $0.95 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) | 2.2 W |
| Long idle (display off) | 0.2 W |
| Off (plugged in) | 2.2 W |
