My laptop has died this morning it worked fine then I came to use it again later on and nada. Upon clicking the power button you get no power at all also no lights to say it is charging etc I tested my charger with a multimeter and it works fine and tried powering with battery out and still nothing. Ive had it apart and checked the power supply connector on the mainboard and the solder joints are fine after peicing the laptop back together it fired up fine but just said the date and time are incorrect and warned cmos had been set to defaults. But I then shutdown and now it wont fire up again. Any idea what is causing this??? It's not a software issue thats for sure.
 
The cmos on the notebook is connected to the pc via a black/white cable that has the battery coverd in a blue plastic that seals it in from contact. So it doesnt sit bare on the board... How do you replace these as I have loads of cmos batteries.
 
The old Travelmate's had fairly a common faulty with similar symptoms, try holding down the power button for 5 - 10 seconds, then release it and then try powering on as normal.
Used to get these a lot, the units failed to power off properly but show no indicators as to the status, holding the button down forces a shut-down of power allowing you to power up as normal...

A long shot if you have already opened up the unit but worth a try.
 
you need to get a multimeter on the contacts on the end of the cmos bat connector, there should be a very tiny bit of metal exposed in the pins to do it, you cant just replace the battery as its spot welded to the cable so dont bother taking it out of the plastic coating.
 
Just tested it by peeling it back slightly and I get round about 3V which would be right.

Tried holding down power but nothing not even any noise of power.

Last time i took it apart and peiced it together it worked but it worked as soon as i put the battery in place I didnt click the power on to power it up it just started loading. But after shutdown nothing like it was originally before i took it apart.

What we thinking then, that something has gone on the mainboard? Or is there any other suggestions?

Cheers All
 
Happened on my old acer also, funny this but I worked out that if i put pressure (from the case) on the front right hand side of the machine then it wouldn't power up. I finally resolved it by not bothering to do up 2 screws to the front right of the laptop. Hardly a resolution but its working 3 and a half years down the line.
