A500+ won't boot - flashing power LED

@r_welfare:

The A500+ has a NiCd clock-battery that leaks and eats away the tracks of the motherboard when it gets old, you better check it.

Other than that, press firmly on all socketed chips as they have a tendency to work their way a bit loose from the sockets with time. Keep in mind that they might look seated, they wont literaly pop out of the sockets . Still, just press on them firmly.

The whistling from the power-supply might very well be that the laquer of a coil or a transformer isn't keeping everything still nowadays and thus gives of a sound. If so it is harmless and might silence when it reaches working temperature.

Yeah, you should remove the battery ASAP and clean away the stuff that has leaked onto the motherboard so it doesn't eat more of it.

Quotes from this battery repair guide:
"Obviously the battery needs to be removed. If you simply can't be knackered fixing the computer, the least you should do is remove the battery using a small pair of sidecutters to cut the 3 legs holding it to the motherboard. This will stop further corrosion."

"Using a combination of the toothbrush and rag, clean the visible corrosion damage from the board using the methylated spirits or isopropyl alchohol.
You can scrub quite hard with the toothbrush with little risk of damage. The components and soldering are quite robust."

Btw, the battery is not needed for the Amiga to function, so don't worry too much about replacing it.

Not regarding the battery, but also do not forget to try what I mentioned about pushing the socketed circuits into place as it is often the source of old Amigas not working.
