Hey all,

My older Laptop from Fujitsu called Lifebook E8410 e-Series will not start.
The fan is running, nothing more. The key light with two opposites arrows are blinking.
I replaced the ram's but didn't helped.
After disassembling I couldn't find a short circuit.
By injecting 19V with a bench power supply the cpu, gpu becomes hot up to 60 degrees C without starting.
1,05V is measured an the CPU socket.

Is it normal that cpu/gpu becomes hot without starting?

Hey all,

My laptop Acer Travelmate P don't go in the bios. Only the power led is lightning for approx. 5 secs and that's it.
Bios battery was replaced, didn't help.

Caps are ok.
Everything like fan, sdd and more are removed.
During the “booting” in the bios the powerconsumption with an additional variable power supply at 19V DC the power consumption is around 1,8W. In standby around 0,3W.

I have measured the powervoltage at KB9022 with an oszilloscope and is fluctuates in the booting +-0,3V.

The buck converter...
