Anyone know where the lid switch is located on a compaq v5000 laptop. My display keeps going blank and if I close and then open the lid it flickers back into life before going off again. Any help greatly appreciated....

    Same problem. If you get a flashlight and shine it at the screen, you can see the video is there - just no backlight. Would like to know where the switches are myself as HP says it is out of warranty.

    I cant find an actual switch on the exterior of the machine. any chance it could be internal?

  • got a hammer Dec 06, 2007

    I am having the same problem with my HP Pavillion DV5218nr.



    Haven't solved the problem, but I have gotten further on my own than with the (lack of) help from HP.



    The plastic strip above the keyboard and immediately adjacent to the monitor can be (at least partially) removed by prying the hinge caps off where the monitor pivots. This manual reveals this http://h10032.www1.hp.com/ctg/Manual/c00....



    On the lefthand side, under this plastic strip, there is a small cable going from the laptop to the monitor. Not sure what this is, but I believe my problem is located either within this cable or beneath this cable. When I apply a slight bit of pressure to the cable, I get my screen back.



    Not sure about a long term fix and cannot find anything having to do with actuator switch replacement...but I do have a hammer.



    Good luck to you.

    Yes, I have the same problem (One year old V6150NR). Display flickers, I don't know what to do, after a few tries on display setting changes, but, still, it keep blinking.

I had a similar problem with my HP/Compac nc4200. Every time I had had the lid closed, the display would be black for a couple of hours, and then work again. I realized that the machine belived that the lid was still closed, and started looking for the lid-switch but I could not find it! The answer is that there is no mechanical switch! In the lid by the microphone (3 cm from the left hinge) is a small magnet hidden and in the base unit by the switches is a magnetic sensor (probably a hall-switch). Over time the the metal next to the sensor has been magnetized by the magnet enough to activate the swith even when the lid is open. The solution was simply to take a magnet and sweep it over the area a copule of times, and suddenly the screen came back to life! I am not sure for how long this fix works, but now I know how to fix it again.

Hii
My notebook is HP but I think these information would help you:

I should tell something about my HP Notebook case ( HP Nightmare)
My sister bought HP DV6338se notebook. It is special notebook !!!, What a special notebook!! As HP DV6000 series have BGA chipset problem, My sister notebook went down step by step; First we lost "Wireless Adapter", Second "Lan Adapter" and Finally we lost everything, It was not working. We bought it from US but We live in TURKEY. We tried to get it repaired in TURKEY under Global Warranty. HP Turkey has not intent to repair it, so I have to repair this silly branded notebook on my own.
I have purchased mainboard from Ebay. I choose different motherboard because original motherboard (HP Spare part number 443775-001) VGA chipset was embedded Nvidia Go 6150 and its performance was too bad for me, so I choose DV9000 series motherboad (HP Spare part number 432945-001) its VGA chipset is Nvidia Go 7600 (256Mb dedicated RAM).
I thought, both mainboard are in same shape but They aren't so I had to do some work on this new motherboard
1.Second Hard Drive Port removed (It didn't fit my notebook enclosure)

2.Front side chassis, Power LED, Battery Charge LED and HDD LED and their resistors are replaced from broken motherboard (443775-001) and placed in new motherboard (432945-001). Because DV9000 series motherboard's Power LED, Battery Charge LED and HDD LED's are in additional card and mine doesn't have such a card and doesn't place in chassis to put it in

3.Caps lock LED and its resistor are replaced in new motherboard (432945-001) because LED place doesnt fit for my enclosure.

4.Touchpad switch , touchpad LED and their resistors are replaced in new motherboard (432945-001) because toucpad switch, toucpad LED' place doesnt fit for my enclosure.

5. Battery connector removed back. (That was the hardest job to do, It wasn't easy to disassemble from board )

so I thought I had completed everything but I realized that My screen back light doesn't turn off when I close lid.
I did some search in Internet and with comparing two motherboard, I found the LCD Back light Lid Magnetic Switch.

[B]As mentioned above there are no mechanical switch inside notebook. There is only magnet in LCD enclosure and magnetic sensor switch in main enclosure.
magnetic sensor is 3 pin electronic part. It is like a BSD type transistor. I have look with magnifier and its part number " FD720 " It is located , just above external VGA port ,in motherboard.[/B]

My new motherboard doesn't has this part so I remove it from my broken motherboard to new motherboard.

I will try to attach pictures to show you,

Now it is working very well.

When I got problem with HP DV6338 notebook, I did some search and learn that I am not alone. Too many people are struggling HP notebook problems. With my experiences I learn that HP is not good at producing notebook, They are good at producing printer only.Other problem is that, They do not care their customer.I think that is main problem for HP.Every electronic stuff may go down or broken but good companies provide good,fast and reliable solution for their customers. I am sorry to say that but HP doesn't provide.

I hope these information's help others.

I solved my problem.

The cable I mentioned terminates at a pretty weak connection just above where the power button is located. I believe what happens is that every time I jar the laptop, the connection wiggles loose, until eventually, the screen acts up. This explains why the screen will flash and why if I applied pressure in just the right place, the screen would come back.

I tested this theory once I figured out it was the connection. I am using my laptop now and the screen works fine again. I can even turn it upside down & shake the hell out of it.

To get to this connection, you must remove the Switch Cover and the Keyboard.

I hope this helps everyone.

Sounds almost like it's going into hibernation mode by itself. I could be wrong but I think it's located towards the rear of the keyboard and almost under the LED assembly.

    This is some additional information that may help.

    The Lid Actuator switch is a small button
    or switch located above the keyboard near the hinge for the LCD.
    Pressing this switch when the computer is on may turn the notebook
    display off, or it may cause the notebook to enter a different power
    state.

    Press
    the switch 2-3 times while observing the display. If the display does
    not return to normal brightness when the switch is released, the switch
    may be sticking and need to be repaired.

    Not sure about this specific model. Some laptops are being manufactured with magnetic switches, so they wouldn't be visible. But I think this one should have a mechanical switch.

There is a switch that controls the on/off of display when the lid is opened or closed. Sometimes it's located near the hinges. Perhaps it's been damaged, loose, dirty, etc. Unplug, remove battery, plug in, reboot.

Have you looked for service manual at HP support website already? It could have pictures showing the location. CLICK HERE

Some newer models don't have a visible switch. Instead they use a magnet inside the lid that triggers the switch when closed. That can very well be in the palm rest or anywhere else.

Lid switch shorting somewhere. In this model there is no pin that I can ses. But after removing bezel it flickers but I need the location of the lid switch to check. When opening lid slowly it sometimes...


Probably not a lid switch related problem. In the more modern Toshiba's, the lid-close switch is generally located either above the keyboard area or underneath the front end of the palmrest (towards you), and the lid-close function is activated by a magnet located either above or below the screen. Best way to check if the lid-close function is working properly is to use Toshiba's power management to set the system to go to either stand-by or hibernation upon lid-close - and if the computer goes to stand-by or hibernation when you shut the lid, then that part is functioning properly.

A better, more detailed and precise description of the problem with the screen will probably help in addressing the real problem.

Has a Toshiba Tecra 9000 won't power up. Power light on front is blanking which appears to be a code 3-3-2


The problem is cause due to one of the following: the backlight or the display, check your monitor brightness settings. Sometimes your brightness may accidentally have been all the way turned down, resulting in a blank/dark screen. The monitor controls are on the keyboard, directly above the numeric keys.
Look closely at your laptop's screen if the steps do not restore power to it and if it remains blank. Can you see a faint image on the screen? If so, the backlight may be off due to the LCD "lid close" detector malfunctioning. This malfunction likely happened due to the lid close switch being stuck in the "closed" position even though the lid is open. The switch is located beside the LCD's screen hinges, and tapping the switch a few times should unstick it.
Use an S-Video cable and plug your laptop up to an external monitor, such as your television set. With the laptop and TV hooked up, turn both on and see if your computer's desktop is displayed on the TV. You can also use a fifteen ( 15 )pin monitor desktop monitor by connecting it to the blue fifteen ( 15 ) connector at the side of the laptop if you cannot see anything on screen it is the display problem. If it is, your laptop's display needs to be replaced. If not, your motherboard and/or video subsystem may need to be completely removed and replaced.

Have you tried turning it on and selecting the function key combination for the screen? For example some screens use FN+F7, hold down the Function key and F7 to cycle between presentation modes.

It's either a pin that is close to one of the hinges, that gets pushed-down as the lid closes, or it is near the "latch" at the front-centre of the computer.

If You want test lid switch, just connect A+B together for a monent!
If the monitor flashes on...? Lid switch is faulty.
It is too dificult to change the lid switch, so the easiest way is connect these pins together forever. :))

Dont forget to turn off your notebook... he wont sleep anymore ;))
