Re: Acer Aspire 4520 turn on problem!!
Could be a bios problem, but first I will check current taken from 19 volts adapter. -

take out the battery push hard with both hands on the key board and get some to apply the power.Comment

Re: Acer Aspire 4520 turn on problem!!
If you know how, you should take basic measurements and post your results for better assistance.
I just repaired the same model with similar simptoms. turns out it was a problem of bad GPU joints.
if main voltages check ok try a soft reflow to the MCP67 chip. if that works you may need a good reflow or reballing to the mcp.
here's the motherboard schematic for your model.
