I have a Tecra S2 with the 6600go GFX card.
The machine is great but exhibits the following problem.
After the machine has been off for a while it will not start reliably.
You press the power button. Either immediately after you release the power button or a second later (changes each time) the green power LED comes on. The cooling fan runs at high speed then slows to a crawl a few seconds later (as normal) but LCD does not come on.
Also when it does not boot USB devices are not initialised (I have a product key dongle that flashes if it is not initialised - when the laptop boots correctly this dongle lights continuously - in a normal boot it is initialised before the BIOS ramtest)
I have upgraded the bios a couple of times - it is now at 2.4 (I saw that the power button timings were changed in V1.9) but this has not solved the problem.
I have tried booting on AC power with battery removed, ac battery & battery only - the result is the same.
I can make it start up eventually by holding the power button until the laptop turns off, waiting a few seconds and then trying to turn it on again.
After several of these cycles it will eventually start up. It seems recently that it is taking more attempts to start than it did before.
If I have been using the laptop for an hour or so and then turn it off it will almost always start again first time.
If I put the laptop in standby (orange slow flashing power LED) then half the time it will continue when the power button is pressed - the other half the power LED will go green but the LCD will remain off & I have to cycle the power button.
As you can imagine this is driving me nuts!
Any help or advice would be gratefully received.
Thanks in advance,
