hello i got new replacement laptop battery for my ThinkPad A30. when i charge the batter it makes high pitch noise when it's charging but when i remove the AC it stops. is this normal? thanks you.
Its a common thing with batteries it makes absolutely no difference to the actual performance its just quite annoying...
Yeah its a common thing with laptops and pretty much anything with high grade rechargeable batteries.
Yeah, some motherboards have the problem also. One of the components actually vibrates very quickly, making a sound.
thanks for your replays guys now it doesn't make loud noise as it did for first use. and it seems it's going down. thank you all
