Toshiba Satellite Pro C660-2DH Not Powering On

[beancole]

Only other thing I can think of that we have seen with Lenovo T410 laptops is that the power on button is apart of the keyboard and the power on button becomes faulty and the only way to sort it is to replace the laptops keyboard ( assuming that the power on button is apart of the keyboard itself ) ?

 

Best piece of advice.

 

Most likely the motherboard has fried. Check the keyboard failing that look in it check to see if there is a power supply. Some laptops go though the battery etc but some go directly into the motherboard (Then charge the battery after(sorry if this is an egg sucking lesson)). If the power cable goes directly onto the motherboard and it doesn't fire up past a bit of fan spinning then it can only be a few things;-

 

A Goosed power button/keyboard that is sending the wrong signals(usually some sort of pushed in button)

A Goosed Processor (beyond unlikely and usually you would get a little more before it dies beeps or something but not a definate)

A Goosed motherboard

 

RAM, wireless, other random stuff plugged into a motherboard would give you some form of beep if that were faulty(in theory. but hey, I still find myself liking memory when I get 3 post beeps so who knows)

I had a home job laptop do this on me and it gave me heart palpitations! The one in question only came back to life after essentially a strip down and rebuild. Removed cpu, ram, wlan mini card, BT mini card, HDD, CD drive, monitor, KB, batt. And then put the minimum back in (HDD, CPU, 1 stick of ram, external monitor, external KB) and it booted. I then went through the one-thing-at-a-time process untill something stopped it from working. Turned out in this case that it was the BT card. Left it out and it ran happily for days on soak test.

 

The above is going to be the best thing to do. If it still won't power on then remove the RAM and try to power on to see if you get any beep codes

Ok I thought I would hop in here in case anyone has the same issue as I have just fixed one of these with the same fault. Essentially the chassis on these C660's is terrible - it flexes a lot and as such the motherboard itself flexes as you transport the laptop around. This can cause dry solder joints in the big Ene chip near the processor socket - to fix this chips solder connections need to be reflowed using either hot air (easier) or a soldering iron with a small tip (harder).

I hope this helps someone in the future who has this fault!
