[QUOTE="pigoo3, post: 1768321, member: 56379"] Not strange at all. Alkaline batteries and battery chargers have been around for decades. Not even close to being as good as today's Lithium Ion rechargeable batteries. But back in the day before Nickel-Cadmium and Lithium Ion batteries...rechargeable alkaline batteries were the best there was. [URL]https://www.amazon.com/dp/B00HYIH0AY/?tag=macforums0e4-20[/URL] Now this is not to say that the battery in an LC 630 is rechargeable...but maybe it did pick up a bit of a residual charge...which may dissipate as quickly as it was gained. With the high-pitched sound you mentioned...I'm betting the PS is a goner & needs to be replaced. Which is probably not worth it on such an old computer (unless cost is not a concern). - Nick [/QUOTE]
