They said they are going to double check the hardware, they they double checked it and said the same thing again :/

p.s. As described in my other thread, the N900 actually "knows" that a USB cable is plugged in because the led glows yellow when the battery is totally depleted and when there is some juice left in the battery, it vibrates as when starting up, blink orange few times, then Nokia logo and dots show up and it reboots just to start to whole process from the start and it loops it until the battery is totally drained - this only happens when the phone is turned off.

If i turn on the phone using a charged battery, maemo boots normally, everything works except it drains the battery really fast, it heats up a bit and it does not detect the wall charger or the PC USB cable.
