#1761 — Compaq NX 6110 lid button defective - bypass possibilities

Hi there.

I've had the nx 6110 for quite a few years, and had it cleaned a few days ago.
 
The reason for cleaning was because I found it would just switch of some times, and I believed it was because of overheating.
 
However, the problem seem to be with the lid button (lid switch?) that is supposed to detect when you close the lid of the laptop.
 
When the machine switch off unexpectedly, I can get it to switch on by just touching this button softly.
 
However, it has been getting worse after cleanup! I must touch this button every 5 seconds!
 
I opened it, and found that the button is soldered to the motherboard.
Does anyone here have an idea on how to bypass this button please?
 
Thank you.
Werner in the windy city...Capetown, South Africa.

You should have some options in the power settings (control panel) for what it does when you close the lid.

BIOS and Control Panel is not an option.
The thing dies before I get there. Replaced the HDD but still same symptoms.

I was hoping to bypass the switch on the motherboard.
Take it off, and solder a wire across.

Anybody else tried this before?

Isn't this usually a reed-switch with a magnet in the lid? Wouldn't removing the switch without a jumper installed solve the problem? (From my limited knowledge of laptops!)

	At least on older models it's a simple pressure switch activated
by a tiny plastic plunger that sticks up near the hinge.  Usually fails
the other way, though, and won't close.

	The easiest solution is change the power settings to do nothing
when the lid closes.  Before I just dyked it out I'd slip a guitar pick
under the edge of that little plunger and see if I could stretch the spring
back up...  The spring and plunger will be part of the *case*;only the
microswitch will be on the board.  You could just pull it out of the little
hole and see if that fixes things.

	On a really old (circa 2000) laptop, it's not even on board.  The 
switch will be on the case part itself and a wire with a connector runs to the
board.  That's even easier.

The question is: "What does the switch do?"

The switch has 2 contacts. What are they? 

Possibility 1: The switch ties a data line to ground.

Possibility 2: The switch ties a data line to +Voltage.

To avoid noise effects, mostly a resistor is somewhere in the circuit.
The most logical way: that this transistor pulls to +Voltage.

If you take out the switch, the contacts still remain there, and are
subject to electrical noise. 

Next question: Does the switch OPEN when the lid is closed, or does it
short-circuit?


Your taking out the switch may cause damage to the mainboard, and the
switch is gone. But the problem still might remain. THe time that you
mention might be the time of a software waiting loop AFTER some action
took place. Taking out the switch would mean to cut off you only means
to keep the computer alive by again and again activation a watch-dog
loop. 


Try to find out about the 2 contacts of the switch - and where they lead
to. Might me there is a little hair crack in those circuit lines leading
ot the switch. Are you able to measure the voltage at the contacts of
the switch? 


I know, what I wrote sounds very simple. But in real life it is damned
tough. Ever tried to open a digital camera and look at one of those
switches there?

Symptoms are ambiguous.
What does "switch off" mean?
Turn off display?
Sleep?
Hibernate?
Full power off?

Unless you spilled liquid in it, the switch is not likely bad.
Put your digital voltmeter across the switch.  Should be some volts
in one position and zero in the other.
The switch likely requires momentary contact.  Shorting it might
not result in a working computer.

I've seen the plastic parts come loose with age.  Or if reassembled wrong.
I've had to glue the levers back in.

Weird things happen when the CMOS battery is right on the edge of 
failure.  Check that.

Don't know how old this is, but if it's got the nvidia chipset
that comes unsoldered, you'll get weird symptoms.
