Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
A few days ago my laptop gave me problems, when I wanted to turn it on to my surprise without charging so I did not put much importance on it, after that I turned it on with a charger, it turned on and charged the laptop, the problem with the laptop is that when it is turned off it turns to turn on after seconds, sometimes at 2 or sometimes at 8, other than that it works normally, I already checked many things, I changed a mosfet at the charge input to a pnp but it remained the same, after that I checked and I did not find anything outside Normally, before that, it had a failure where I changed... -
Hi all! I have a problem with Pioneer VSX-D1011 – it don't turn on when the amplifier is disconnected from the socket for a few minutes. Standby LED doesn't light up. I'm a beginner in electronics, so I'm not very good at reading schematics. I tried to find the visual damages of components but I didn't see anything wrong. All of the fuses are ok, both of the switches the same. Have you any idea where should I start looking for? Once on every 100 tries I am able to turn it on, but what can it depend on? -
car radio CD:98067084XT
display:9801219480-01
The button for turning on the device does not respond and the display is black - there is nothing. I have given a description of the measurements in the picture, only the voltage on the white wire is sometimes 5V and sometimes it is 12V. Only the background light on the device works when the position is turned on. The customer says that the display works occasionally and then the device works normally.
Please help me, what should I do next?
