30 second Delay when switching on.

The problem was, that it kept rebooting mid-bootup. I am re-installing with a new HD and it seems to be ok.

Hi,
My SB75G2 has had a similar problem - long wait between pressing power button and anything happening.

Looking in the case when not running, but fed from the mains, there is a light illuminated on the PN15g (wireless receiver) I installed.

To get the machine to boot I have used a hairdryer to warm the motherboard. - Sounds crazy I know, - everywhere else there are forums for maximising the cooling!!

I think I have a 'dry joint' - the solder is not connected right somewhere on the mainboard. A blast of heat and the solder expands and the connection is made. - Presumably when up and running, the latent heat from the machine keeps the connection, - or once booted, this connection is no longer needed.

I'm going to have to get it sorted - I guess a tech shop to check the connections. - I'll make sure the cost is not more than a new MB first!

Cheers

My SK41G had an identical problem - I would press the power button, then it would do nothing for 20-30 seconds before humming into life.

Problem was the PSU - I came to this conclusion after I attached a spare ATX PSU & the machine booted straight up instantly. After removing the faulty PSU I cracked it open to take a look inside, & the only obvious damage was that 2 or 3 of the capacitors had overheated at some point & were leaking. This explains the wait, because if the capacitors were damaged then it may well increase the amount of time it takes for them to charge up to the required level. I bought a new PSU & it's been running fine ever since.
