Amilo PI 2515 power off suddenly after same time

Thread Starter 
Hello all
I have one Amilo PI 2515,received with damaged cpu fan.
I replace fan(not Fujitsu original one),and clean old thermal paste and put new AS5.
Since I encountered problems and fan was not starting (maybe because was not need,cpu is not warm too much) I take power for fan from usb so now fan is always on and at max rpm.
I leave two wires still connected to fan socket (black-gnd,yellow-rpm sensor) only red is connected to +5V from usb socket.
Problem is that always notebook power off at very some time.
I did some test,with a little human error about timing.
From powering on until shut down is around 3 minutes and
16-17 seconds in any cases.

Power on enter bios:
3:17.8 -shutdown
3:17.6 -shutdown
3:17.0 -shutdown

Power on run memtest from cd
3:16.6 -shutdown
3:17.9 -shutdown
3:16.2 -shutdown

Power on boot linux
3:17.9 -shut down
3:17.5 -shut down
3:17.1 -shut down

I have already loaded defaults from bios,upgraded bios to newest version from support leave motherboard without bios backup battery for some time but problem persist.
I can't measure cpu temp but is cool enough in my opinion and compared to another notebook seems lower than 60 celsius.
Anybody have some ideas what can I do next?
Thanks.

well it posts, thats good. Try swapping memory out or swapping other peripherals see if it gets further.

Thanks for answer.
Memory tested on other notebook.
Tested with other memory too but same result.
HDD is removed,only dvd unit is used and tested with other too.
Removed wireless card.
Battery seems to be dead but with or without battery same result in 3 minutes and ~ 16 seconds suddenly power off.
I can't install anything on because of that.
I'll try ubuntu on usb hdd maybe with lm-sensors I can see if something is wrong but since cpu is not too hot,temperatures and voltage must be ok.

A remote chance that the 3rd party fan replacement is not performing 100% (??)

cheers ...

Could be.
Now I put two PSU fans to blow air into cpu heatsing which is cold now but same result.
I need to setup lm-sensors into ubuntu usb-hdd and give a try to see what is reading from notebook.

If it is cool (GPU and CPU area) then it is possible that the board did not record (interpret) the temp correctly

I'll investigate more on hardware problems.
Could be a power problem,since battery is dead but even on charger I have very low voltage on few pins.
Anybody know what;s the pinout for this battery to make folowing tracks of power more easy?
I can't find on net.

There is a post with link to many brand/model schematics. Want to browse through it?

Bummer. I don't know much about batteries. You might want to post in the Battery Fuel Section of NBF for the pin info

cheers ...

Pinout seems to be
1- (big one pin) GND
8 - + battery
Charger IC seems to be TL594C but is not powered
Charger voltage exist on MOSFET (power transistors) on charging part but not on IC who drive them.

Would you post a pic to go with the description? It would be easier to follow.

Have you looked into the power switch area? You could have a short there.
