Chapter 11. Troubleshooting problems

This chapter describes some common problems and suggested solutions, and how to recover your tablet
from a crash.
Be aware that the problems and solutions described in this chapter are meant only as a guide. They are
not definitive problem solving techniques. For some problems, you might need help from Lenovo, your
reseller, or your service provider.
When you observe a problem, stop operation immediately, because taking further action might result in data
loss or damage. Take a note of what the system is doing and what actions you performed before the problem
occurred. Provide detailed information to Lenovo or your service provider for quicker problem resolution.
Internet problem
Problem: Unable to connect to the wireless network
Suggested solution: Make sure that:
• The SIM card is valid and workable if you are using a mobile data network (2G or 3G).
• You are within the network's service range and the signal strength is good.
• Your tablet is not in Airplane mode.
If the problem persists, contact Lenovo for technical support.
Multitouch screen problem
Problem: The multitouch screen responds slowly or improperly.
Suggested solution: If your multitouch screen responds slowly or improperly, do the following:
1. Remove any protective covers from the multitouch screen. Protective covers might prevent the tablet
from recognizing your inputs and are not recommended for touch screen devices.
2. Ensure that your hands are clean and dry when touching the screen.
3. Restart your tablet to try again.
If the problem persists, contact Lenovo for technical support.
Battery problem
Problem: The battery does not charge correctly.
Suggested solution: Check if the ac charger is connected correctly. If the connection is good but the
battery still does not charge, contact Lenovo to replace with a new battery.
System problems
• Problem: Unable to turn the tablet on.
Suggested solution: Connect your tablet to an ac power outlet to see if the problem is caused by a
drained battery. If the problem persists, contact Lenovo for technical support.
