Short Circuit on motherboard Acer 5738ZG

Hi, I have issue with repair 5738. Perhaps this Notebook was damaged with wrong polarity on power supply input. I think some electrical element on motherboard was destroyed. Bud I dont known how transistors switching or which element can be damaged. I remove element for DC 24V 1,1A and measure + oposit - still has 0 OHM. So I dont known where is short circuit. If you have some good idea or scheme power part on motherboard please inform me. Thanks.

My Acer Aspire 4750G-2312G50nbb does not turn on, Whenever I insert the charger adaptor to the power jack, the charger adaptor led light turns off.

One of two issues will cause that.1/ The socket is damaged and presenting a short circuit to the charger or 2/ The protection diode has blocked an incorrect voltage/polarity and provided protection by going short circuit.

Have reversed polarity and is no longer open and no longer charge the battery. You can help?

Applying a power supply with reverse polarity to your Acer will have damaged the motherboard and possibly other components. This notebook is beyond repair.

Hi - For some reason, the printer will not turn on. I have checked all connections.

Also, are you sure that the replacement power supply was compatible with the old one
was working on the problem. There was nothing wrong with power supply or motherboard. I disconnected everything and left only power supply connected to motherboard. When I turned on the power switch located on power supply nothing happened. Then I short the power sw pins located on the motherboard with the help of a screwdriver. The motherboard came to life. The I connected all connections again. I don't know whether it was a static charge developed on the board or reverse polarity ... May be you can explain it better as I am a newbie in hardware world. In nutshell problem is resolved.

Power supply issue

sound like they have damaged the "new motherboard" when have installed it at the shop. Or they installed a cheap brand and it's not correctly sitting in the base. should ask them to show you the old motherboard they removed to make sure they haven't just fudged-up the old one.
