Lid switch location??????????

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....

Compaq V5000 backlight is out. I can see the logo during POST and Windows boots, I can see the Welcome Screen.

I've hooked up external VGA, it works just fine. I've swapped 3 LCD panels that are known good and 3 inverters known to be good. Same problem on all of them. I cannot find any information on the switch, whether or not it's magnetic, etc.

I'm stumped.

    Thanks, I've already tried that. I think I should have probably worded that better. After reading your comment, and rereading my post, I see how you interpreted that.

    When I say I can see the logo, etc, I didn't mean to imply that the backlight works until the Welcome Screen. What I meant was, the backlight is out, all the time...yet I know the LCD panel and the video card work because I see text on the screen, etc. This is a hardware problem, no doubt. For whatever reason, I can't get the backlight to turn on, and I've swapped out the usual suspects and tried to adjust the brightness with the FN keys. I'm using a parts mule DV5000 (an HP), so I know the parts work. I've done cross references on the inverters, and they are the same. The LCD panels are identical between them. Yet I get no backlight. I've hooked it to an external monitor, so it's fine through that output.

    If it's not a switch stuck somewhere, I think it's a motherboard issue. I worked on some Dell laptops that had magnetic switches to tell the computer when the lid was closed. I don't see anything like that, so I'm trying to figure out how this thing knows the lid is closed so I can test to see whether or not that is what the problem is. I'm thinking the switch is going to be on the bottom of the latch in the base of the laptop, under the touch pad, on the board. I was hoping it wasn't going to be there. It's probably not something you can easily fix, either. I was just wanting some confirmation before I start ripping that thing apart all over my bench.

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 ;))

Hi, I have a hp pavilion dv2000 one day just the backligth of LCD dont work. First I think in a inverter problem, later an lamp problem. But after some days I did find many people have the same problem with this model (dv2000); and 90% the problem was a fail in LID switch (magnetic detection) to know if the LCD is open or closed. So the main board think the LCD is closed and for save energy keep turned off the LCD backligth. In my laptop the problem can be workaround by disconecting the lid switch . I think the V5000 series have one LID1 connector like the DV2000 series. You can get more info in the next link
Good luck. I hope this info will be usefull for you.

I think it is the power converter somewhere in/on the mainboard, ore close to it, you have a converter from 12 to maybe about 100V ac or dc, this converter seems to me is being to old, and it is probably a capacitor in that circuit there is dry. you need to have a diagram and positions drawing to start soldering this problem.

Best regards

I have an hp pavilion dv2000 and with a similar problem. The lid switch fail and the laptop 'think' or 'guess' the LCD is closed. So the main board send an signal to the inverter to turn off the LCD backligth to save energy. In this model (dv2000) the touchpad and the multimedia buttons going to 'sleep' too when the laptop 'think' the LCD is closed over the keyboard. After read about many people have the same problem with this series of laptop, I did find the solution. I think other models from hp like V5000 must have too one connector labeled LID1. In my Laptop the problem can be workaround just by disconnect the lid switch, a little 2 pin connector under the keyboard (around the center). There are 3 conectors in this area, the LCD1 connector (with many pins), the LID1 connector (with 2 pins), and the CAP1 connector. You can get more info from this link...
good luck.

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.

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.

Anyone know where the lid switch is located on a asus 900? i have a feeling it stuck...

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.

Lid switch location??????????

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.
