I had for some time problem with my Acer Aspire 7535 laptop that it wasn’t turning on. The power light was on, the fan was working but nothing else. It was helping to turn off-turn off cycle and usually after 10-15mins it was starting to boot. Recently it “died” completely and as I needed laptop ASAP I’ve bought another one and putting faulty aside. After holiday my wife rushed me to do something with it “fix it or bin it”, so I’ve searched and nothing worked, then I’ve recalled that after successful boot the laptop had time/date not updated which gave me an idea to replace bios battery. I’ve looked at the acer laptop manual, I’ve found how to disassemble it and replaced flat battery. After doing this laptop started to work again:)
No beep, power-on indicator turns on and LCD is blank. – check bios battery 🙂
