While connecting to computer w700i gets disconected automaticlly

14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

Note:
"O" - Frequency measured and fan speed fixed.
The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

Step 1: Reset the printer

1. Without turning off the printer, disconnect the USB cable from the rear of the printer.

The USB cable connects to the port on the rear of the printer. The port is labeled with the USB icon . If your printer has a network or wireless connection, ignore this step.

2. Remove the ink cartridges from the printer.
3. Wait until a message to insert the ink cartridges displays. If you do not see a message within a few minutes, skip to step 4 to disconnect the power cord.
NOTE: If your printer does not have a control panel, wait until the ink cartridge lights blink. If the ink cartridge lights do not blink within a few minutes, skip to step 4 to disconnect the power cord.
4. Disconnect the power cord from the rear of the printer.
5. Wait 60 seconds.
6. Reconnect the power cord. If the printer does not automatically turn on, press the Power button.
7. Reinsert the ink cartridges, and then close any open doors on the printer.
8. If you receive a prompt to print a calibration page, do so.
9. If you disconnected the USB cable, reconnect it to the rear of the printer.
10. Try to print.

If that doesn't work you can log on to HP.com/Support and Drivers.
Find your device and search the error codes listed.

disconect battery for 10/15 mins when done touch negative cable to positive battery terminal(while negative still un hooked)reinstall.some codes cannot be cleared with scanner,or still has problem so lite wont go out

please check following points:-
1) IP address (some wireless AP's follows ip address such as 192.168.1.1 for AP and 192.168.1.2 for 1st workstation, 192.168.1.3 for 2nd workstation and so on).
2) check connection options in IE. it should be lan setting and detect automatic setting and use automatic configuration script(put IP address of AP)
3) if DHCP is enabled then obtain IP automaticlly
4) check for any WEP security options i AP.
5) user must have internet access rights.
6) if Static IP is Used please give gatway ip (your AP's IP address) and same for DNS IP address.
then restart your system and enjoy internet.

for connecting mobile u have to first install the mobile dtrver sony ericson than conect it to computer.

are u on vista
