Wireless connectivity issues
Wi-Fi speed is slow
l Your network is running slow for all devices.
You should first check to see whether your network is slow on another device. Can you
connect to your wireless network and browse the web at normal speeds from another
device? Try running a Network Speed Test to ensure your Internet connection is
functioning normally.
l Your Wi-Fi signal is weak.
Look at the wireless network Wireless network icon icon in the taskbar.
This icon shows your current signal strength. If the icon is partially dimmed, move
your device closer to your wireless router to see if the signal improves. If your router is
broadcasting on both a 2.4GHz and 5GHz frequency, try connecting to a different
frequency. In general, a network operating on the 5GHz frequency will be faster and
less susceptible to interference, but will have a shorter range than a 2.4GHz network.
Power and battery issues
Battery will not charge
l The battery is overheated, or too cold.
The battery will charge between 0 °C and 40 °C (32 °F and 104 °F). If you have been
using or storing the battery and/or device in a particularly hot or cold environment, the
battery may be outside the safe charging temperature range. Sensors in the battery
will prevent the battery from charging until its temperature returns to a normal level.
l The battery is not installed correctly.
If the battery is not installed correctly in the device or the battery charger, it may not
have a proper connection and will not charge.
l The battery terminals are dirty or corroded.
If the terminals of the battery are dirty or corroded, it may not have a proper
connection and will not charge.
