WiFi power cycle
If your computer is unable to access the Internet due to WiFi connectivity issues, a WiFi power cycle procedure may be performed. The
following procedure provides the instructions on how to conduct a WiFi power cycle:
NOTE: Some ISPs (Internet Service Providers) provide a modem/router combo device.
1. Turn off your computer.
2. Turn off the modem.
3. Turn off the wireless router.
4. Wait for 30 seconds.
5. Turn on the wireless router.
6. Turn on the modem.
7. Turn on your computer.
Diagnostic LEDs
Instead of beep codes, errors are indicated via the bicolor Battery Charge/Status LED. A specific blink pattern is followed by flashing a
pattern of flashes in amber, followed by white. The pattern then repeats.
NOTE: The diagnostic pattern will consist of a two-digit number being represented by a first group of LED blinks (1
through 9) in amber, followed by a 1.5 second pause with the LED off, and then a second group of LED blinks (1 through
9) in white. This is then followed by a three second pause, with the LED off, before repeating over again. Each LED blink
takes 1.5 seconds.
