Stamina/speed switch My stamina/speed switch stopped working recently. The green light indicator is on stamina mode,while the switch is set on the speed mode. I tried adjusting options in the Vaio Power Managment tool, but it did not switch to speed mode. I've been stuck with the stamina mode for a while, and i can't play some video games because stamina mode uses intel graphics, whilst the speed mode uses nvidia Geforce 7400 Go which is better. Would appreciate your help.

    I have the same problem - are you just running Windows or do you have another OS installed? Reason I ask is because I have a tripple booting laptop and when this happened I had to put the switch to the light that was on, boot into Windows and login, change the switch and select Reboot on the popup.

    This only worked for me once. I am convinced that the switch itself is fine - Id like to rule out a software reason too (I doubt it very much also)

    I have the same problem. However, I am using a VGN-SZ330P notebook. I don't know what caused it but I can't play my games anymore and I get blue screen errors all the time when I try to watch videos online. I did a complete system restore and everything, nothing works. Is it my nvidia card? Do I need to get a new one before I can run in SPEED mode?

  • wda33 Feb 09, 2009

    I have the same problem. The only thing i can add is that my
    batteryjust went dead and will no longer accept a charge. Could the
    fact thatthe laptop is trying to charge said battery be a factor in not
    lettingthe system switch back to speed mode? I'm using
    a vgn-sz330p

    I set mine to stam mode (SZ330P) for school and it never went back. Somehow my graphics card has uninstalled itself so im running on the intel chipset card... I've reformatted, downloaded drivers, and messed around in the bios but still nothing :( any help would be much appreciated :D

This IS very likely a hardware problem. I'm not very sure about your model but I know that many SZ users w/ G84xx/G86xx NVIDIA card out there are having similar problem -- could be due to NVIDIA chip failure.

http://www.theinquirer.net/gb/inquirer/news/2008/07/09/nvidia-g84-g86-bad

Sony had just acknowledged this problem (failed G84/G86 NVIDIA chips) recently but unfortunately SZ series models were not included in the list.

http://www.theinquirer.net/inquirer/news/1528907/sony-admits-failing-nvidia-chips-months-late

In case you're using SZ model and are having G84/G86 nvidia card, just give sony service center a call, at least to let them take your issue into their record.

How do i fix cruise control on 2000 ford excursion

TRY THIS Self-Test Diagnostics - Excursion.
[img src="file:///E:/FORD/ELECTRICAL/Speed%20Control%20Workshop%20Manual_files/SYOusenfileani_caut.gif" border="0"> WARNING: This test is a key on engine off (KOEO) test only that is conducted in park only with emergency brake fully engaged.

  1. Enter Self-Test Diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. FIVE ADDITIONAL FLASHES AT THIS POINT INDICATE A DEFECTIVE SPEED CONTROL SERVO. Release the OFF switch.
  2. Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL.
    IF THE "ON" SWITCH IS NOT DEPRESSED WITHIN FIVE SECONDS AFTER ENTERING THE DIAGNOSTICS MODE, THE MODULE TIMES OUT AND THE PROCEDURE MUST BE STARTED OVER.
    The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch.
  3. A lamp flash with the last button (SET/ACCEL) indicates that the STATIC test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective.
    If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes:
    * 2 Flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).
    * 3 Flashes - Deactivator switch is open or circuit defective.
    * 4 Flashes - Vehicle speed signal is out of range or circuit is defective.

  4. Immediately after the STATIC test, the speed control servo does a DYNAMIC test by automatically actuating the throttle lever from 8 mm (0.315 in) to 12 mm (0.472 in) of travel from the idle position. During the DYNAMIC throttle pull, observe throttle movement to witness any binding or sticking of the speed control cable and correct connection of speed control cable to throttle lever. Make sure the THROTTLE RETURNS BACK TO IDLE POSITION.
  5. Return ignition switch to the OFF position

NOTE:
I had it replaced by ford dealer free of charge CHECK FACTORY RECALLS USING YOUR VIN if u don't know how send it to me and i will check it for you it is located at the inner side of the driver door frame.

Remove the trim panels in front of the center console. Locate the engine computer attached to a floor-mounted bracket on the transmission tunnel between the console and the firewall.

  • Turn the diagnostic mode selector, located in a round opening on the side of the engine computer, until it stops. Observe the small red and green LED lights on the side of the computer next to the mode selector. They will flash to indicate the modes, with a pause between each mode. One quick flash is mode one, two quick flashes is mode two and so on. When the light flashes indicate mode three, quickly turn the mode selector counterclockwise until it stops. You have entered mode three diagnostics.

    2002 Ford F150. Cruise control stopped working.

    Did you have the recall done on it ?
    recall 05S28. Description: Speed Control Deactivation Switch.

    It could be a blow fuse in the recall harness, if you did have it done.

    Try the self test, and see what the results are. If you do not get it into self test mode, it could be the fuse in teh recall harness that is blown. The 1st revision of the recall harness was an inline ATM fuse, not sure if the revision 2 was the same. If that fuse is blown, the switch is leaking, and should be checked.

    Self-Test Diagnostics

    WARNING:
    This test is a key on engine off (KOEO) test only that is conducted in park only with emergency brake fully engaged.

    1. Enter self-test diagnostics by depressing the speed control OFF switch while turning the ignition key ON, making sure the engine does not start and is not running. The speed control indicator on the instrument panel will flash once to indicate that speed control module entered the diagnostic mode. Five additional flashes at this point indicate a defective speed control servo. Release the OFF switch.

    2. Press the remaining switches in this sequence: ON, RESUME, COAST and SET/ACCEL.

    If the ON switch is not depressed within five seconds after entering the diagnostics mode, the module times out and the procedure must be started over.

    The speed control indicator lamp will flash as each switch is depressed. Press each switch in the sequence immediately after the indicator light goes out for the previous switch.

    Note:
    There will be a slight delay when the last button is pressed and the lamp flashes.

    3. A lamp flash with the last button (SET/ACCEL) indicates that the static test passed. If the lamp does not flash with the last button and there are no additional flashes of the lamp, the switch is defective.

    If the lamp does not flash with the last button, and additional flashes occur, follow the chart below for trouble codes:

    — 2 flashes - BPP defective, circuit is defective, brake applied, CPP switch or jumper (if equipped).

    The crise on my 2002 F150 stopped working. Occasionally the cruise light will flash when I try to set, but it still won't work. Also, I have had the recall work done, and this problem started after that.

    Could be the fuse in the new harness is blown.

    Try the CC self test, to see what the flash code returned is :

    If you download "driver max" this will find all system hardware, check all driver versions, download the the latest version, or if you want to pick a known good one you can. It looks like, as you have so many OS on your pc. that there may be some conflicts there. But driver max should sort this. Oh and it's free so no worries there.

    How to KNOW the light is right 4 an Olympus OM20 Manual camera?

    OM-20 was basically a upgraded OM-10 with the manual adapter built in and a number of other refinements.

    The viewfinder has LED's to show the shutter speed recommended by the camera's lightmeter for the ISO and aperture selected. It also has an exposure compensation indicator (the +/- symbol) and an indicator for flash ready which doubles up as a post-exposure flash confirmation. There is also the indicator lamp to show manual mode has been selected. OM-10 lacks the manual mode lamp and the +/- indicator.

    Like the OM-10, the OM-20 is primarily an aperture priority automatic camera. In this mode you set the ISO film speed, choose which aperture you wish to use (with the ability to use the lens depth of field preview button) and then the camera selects the correct shutter speed. The +/- exposure compensation control allows the user to tell the camera to modify the recommended shutter speed by up to two stops either way.

    In manual mode, there is no manual metering. The light meter behaves exactly as it does in aperture priority mode and the viewfinder shows the recommended shutter speed and not the manually selected one. Correct metering is therefore a case of adjusting the aperture first, and then choosing the correct shutter speed indicated in the viewfinder. If the user then decides to select a different shutter speed, then the aperture ring must be adjusted to maintain the correct exposure. For example the aperture is set to f8 and the camera recommends 1/60th of a second. The user decides that a faster shutter speed is required and chooses 1/250th, but the viewfinder remains showing 1/60th. In order to keep the same exposure value the user must open the aperture by two full stops to f4. The camera's light meter will detect the new aperture setting and providing the light on the object is unchanged the viewfinder shutter speed display should now show 1/250th as well to confirm the correct adjustment. Alternatively, the user can choose the shutter speed first by looking at what has been set on the control ring (or by turning the ring to the end of its travel and then counting the clicks from there as all experienced OM users do) and then turning the aperture ring until the shutter speed shown in the viewfinder matches what's been manually set.

    It all sounds clumsy and complex but is done far more quickly than I've taken to type this and becomes second nature.

    Aperture priority metering is selected on the camera by choosing AUTO on the mode selecter. In this mode the shutter speed ring has no effect and the viewfinder always displays the automatically selected shutter speed.

    "Cruise" on a 5-speed '00 Hyundai Elantra

    I have this same car. The place you set speed control is on the windshield wiper switch on the right side of the steering column. The button with the indicator light has to be pushed in order to use the cruise control but just because the indicator light is on, it does not mean the cruise is on. Hope this helps a little. If you need more info and someone else doesn't answer more eloquently.. I'll check back and try to give you more info. :-)
