Chosen Solution
I replaced the LCD on an Acer Aspire A514-52 and since replacement the device will not turn on. I’ve tested the power jack with the multi-meter, and when plugged in it gets 19.41v, but the battery charging light does not light up. I’ve unplugged the battery and charger and held the power button, I’ve tried booting direct from mains, nothing happens. Could it be something I’ve done? I have replaced hundreds of these Acer LCD’s and never had an issue like this. Any advice would be greatly appreciated.
Hi @oscart, Is there any voltage appearing on the battery’s red and black wire connection pins on the motherboard (with the battery removed) when you connect the charger? I can’t find a free download online so you may have to purchase the schematics to find out what’s wrong. Although I’m not certain that I linked the correct one as these are for an NB8513_MB_V3 motherboard and not for the model number you quoted. Nothing shows up when searching for an NB851_NB_V3 and the one I linked shows up a lot when searching for an “Aspire A514-52 motherboard schematic”. There are other results when searching for an NB8513_MB_V3 schematic or the laptop model number but mostly they’re just for BIOS.bin files or boardview files and not the schematics. Hopefully it is the one or it is close enough to help.
