T42/T43 not shutting down when lid closed

[Ken Edmonds]

My T42 I rebuilt with an R52 motherboard, so it's a sort of T43, is working perfectly and I'm really pleased. The only thing that doesn't work is going into standby when I close the lid. I can't even see how the switch is supposed to work. Am I likely to have missed something? I can use XP to put it in standby so I'm pretty sure it's how I put it back together.

There's a setting in BIOS that affects this, look for it, I believe it's under "configuration", make sure it's not set to "do nothing"...

Report back and we'll take it from there.

Thanks for the quick reply.
It's quite possible as I hadn't checked the BIOS. I'm off out in literally a couple of minutes but I'll check when I get back in a few hours.

Bum - that's not it. It's set to Suspend when LCD lid is closed.

Touch the button with the tip of the pen and see what happens. The switch itself might be dysfunctional.

[Ken Edmonds]

Already tried that - nothing. I took the bezels off again to check and I can't actually see how the switch is supposed to work. I can see the fixture riveted to the keyboard surround but what does it press on? All I've got is a plate above the LCD connector.

I think that your problem is right there. Can't pull the bezel off my own T43p right now but there should be a piece corresponding by "rising" from the board...

[Ken Edmonds]

That's basically the conclusion I'd come to. I don't want to take the bezel off my T43 either.
I'll look through the box of leftover bits to see if there's two of anything and also see if I can identify what's missing in the HMM.

R52 and T4x have the on/off switch (on the LCD-cable) in a different position.
If you use a T4x LCD cable in your T4x it should work, with an R52 cable it won't.

[Ken Edmonds]

Genius! I've just looked at the screen I didn't use and I can see the switch which is missing on the other one which explains why I couldn't see how it worked. I'm not stripping the whole thing down again just to change the cable so I'll just live with it. Now I know why I don't mind and Fn+F4 works so no hardship.

Thanks - this forum's great!
