I have a sony vaio laptop, model PCG-K215M. it was not used for some time, now it won't power on (no lights, no fan noise, no hdd spin, completley dead).
I've tested with the baterry, without it.
I've took out cmos battery, ram, hdd, nothing.
the power supply gives the 19.7V. The battery is charging while inside the laptop. There is power on the motherboard itself (so the power supply cord and connector are ok).
can you help me and tell me what else should i try to fix it?
