What should the user do if the VAIO computer and VAIO-related products (peripherals) cannot be turned on or do not work?

What should the user do if the VAIO computer and VAIO-related products (peripherals) cannot be turned on or do not work?

The user should perform the following checks if the VAIO computer and VAIO-related products cannot be turned on or do not work:

1. Check if the AC adaptor (battery) and the power cable are the supplied accessories or genuine optional accessories (hereinafter referred to as genuine products).

* Sony guarantees the normal operation of VAIO computer and VAIO-related product only when genuine adaptor (battery) and AC cable are used.
Sony would advise the users to use genuine products of Sony since the use of non-genuine products may cause unexpected problems.

2. Check if the receptacle is live.
Check whether the receptacle is live or not with the use of other electrical products.

* Sony would advise the users to connect the product directly to the wall outlet as much as possible. In addition, do note that when an AC tap is used, there may be an ON/OFF switch for each jack and/or the entire tap.

3. Check if the latch on the machine is pressed while the liquid crystal panel is open (only in the case of notebook computers equipped with ACPI).

* PCG-N505** and later models adopting "ACPI" and PCG-C1XN and later VAIO computers do not start when the latch of the liquid crystal panel on the machine is kept pressed or when the liquid crystal panel is left closed.

# When the latch is not pressed
Refer to the following procedure 6.

# When the latch is kept pressed
Press the latch with something like a slim object.

Note:
To press the latch, users may need a slim object like a clip. But never use an object that may easily break such as lead of a mechanical pencil, as it may cause problems to the machine.

4. Some other checks

a. In the case of VAIO Computer
- Check if the AC adaptor and the power cable are firmly connected to the product.
- If the computer was moved from a cold place to a warm place, leave the computer for about an hour and turn it on again as condensation may have taken place.
- If the computer has not been used for a long time, connect the AC adaptor (battery) and the power cable and leave the product as it is, without turning it on, for half a day (at least 3 hours in order to recharge the backup battery for CMOS) and turn it on again after that.
- For PCG-Z505**, PCG-C**, PCG-F**, PCG-N505** and PCG-FX**
Press the reset switch with a thin object such as a paper clip and turn on the computer again.
- For the machines other than above.
Keep pressing the power switch (button) for more than 4 seconds to turn off the computer completely and turn it on again.

b. In the case of Peripherals
- Remove the AC adapter (power cable) and leave it for one minute. Then, connect the AC adapter (power cable) again.

ID:5798 Why can't I turn on my PCG-C1X*, PCG-C1V*?

6. Check if the latch on the machine is pressed while the liquid crystal panel is open (only in the case of notebook computers equipped with ACPI). * PCG-C1XN and newer VAIO computers adopting "ACPI" do not start when the latch of the liquid crystal panel on the machine is kept pressed or when the liquid crystal panel is left closed.

# When the latch is not pressed
Refer to the following procedure 7 and on.

# When the latch is kept pressed
Press the latch with something like a slim staff.

Note:
To press the latch, users may need a slim staff like a clip. But, never use a staff that may easily break such as lead of a mechanical pencil, as it may cause problems to the machine.

# When the power indicator stays on
1. Reset the computer if it has the reset function.

Note:
To press the reset switch, users may need a slim staff like a clip. But, never use a staff that may easily break such as lead of a mechanical pencil, as it may cause problems to the machine. Note that resetting may damage the data that had created.

2. In the case of VAIO computers without the reset function
Pull the power switch (button) for 4 seconds or more to shut down the computer completely and then turn it on again.

3. When peripherals or expansion devices are connected, turn off the machine to remove all of them, and turn it on again.

4. When memory has been added,
- When the user added a genuine memory to the machine by itself, disconnect the power cable from the wall outlet and connect it again.

- If the memory is not a genuine part, check the computer in the state that the memory is removed. If the removal of the memory improves the symptom, the added memory may cause it. In that case, get in touch with the dealer from which had bought the memory.

5. Disconnect the AC adaptor (battery), leave the machine as it is for about 5 minutes and then connect the AC adaptor (battery).

6. If the machine has not been used for a long time, keep it connected to the AC adaptor (battery) for at least half a day (3 hours minimum) without turning it on in order to recharge the backup battery of CMOS. If the backup battery of CMOS built in the machine is completely discharged, the machine may not be activated or the system may not start.
