Re: acer aspire one kav60 no power
Yup! It won't work because it has no power so you can't enter the bios recovery with crisis disk. It applies, not always but some aspire one with power but no display even you've done the usual stuff isolate memory stick and adapter.
You need to check the standby volts from power switch and also the bios, most likely it 's windbond.Comment

Dear all, I am trying to troubleshoot an Acer Aspire 5 A514-55 that won't power on. I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure. My initial thoughts are battery charger IC and/or ideal diode/MOSFET (that switches between incoming DC and battery power), but I could be totally wrong on this.1) Laptop was working fine on battery, then user realised battery was running low. Plugged in AC adapter but noticed it was not charging (LED on AC adapter plug did not light). Eventually shut down... -
Dear All,
Please really2 need Help on this Acer A515-52G Motherboard Compal EH5AW LA-G521P Rev: 1A.
At first this laptop can on, keyboard light on but no display. Open the motherboard, found out the PQZ3 Mosfet and PUZ3 ic near it burn. Refer picture below. Then I replaced both. All the power rail 3.3,5,1.2, 1.35, 0.8V have power back after i turn on the laptop except for the VCC_GT rail. Voltage at Power Supply showing 0.000A before turn on, after turn on it became 0.5 0.6A. Seem cannot boot and still no display. Then I replaced the PUG1 and mosfet, but the VCC_GT still no power....
