Hello friends, I am having trouble with a hp-ec1001np that detects the headphones or speakers when connected to the jack, but no sound comes out. The normal laptop speakers work fine. Anyone has an idea what it might be? Did a full reinstall of windows, still nothing.

Hello friends,

I have with me a damaged Xiaomi Soundbar MDZ-27-DA, photos will be annexed for reference of the board. Problem I am having, even if I was to attempt a repair, I have no idea what the component is for replace. Does anyone ever come across one of these speakers? The identification of the component would be very appreciated, any kind of schematic would be helpful as well. If you consider if this is a pointless attempt of repair, let me know as well.

Thanks for the help!!...

Hello friends!

Have a situation with a HP Elitebook 840 G1, the computer (when plugged in) turns on the led on the power button and the power led in the indicator leds. The battery led also starts flashing orange. But nothing happens, no activity at all! Tried to program bios with new file but still nothing, always same behaviour. Could it be some damage on the hardware, the chips for the bios? Anyone ever saw something like this happening? Any feedback is appreciated!! Thanks in advance for the help!

Some pictures to identify the chips and the laptop....

Hi Strongtester,
I have read that you had a problem with your Gl553vw motherboard.
I also have a problem, and I need a high detail picture of the boards back to restore some traces. Can you help me with that?

Thanks,
Tomas
