Lenovo G580 - Charging issues

[NJD]

So I've got a Lenovo G580 that's been sitting gathering dust for quite some time due to a battery that wont charge, couldn't tell you what the symptoms it had just before it stopped working as it wasn't me using it, all I was told is that it wasn't charging, although was turning on and working fine.

I've tried;

(1) Laptop with charger plugged in and battery.
(2) Laptop with charger plugged in without battery.

Nothing, not a sign of life, no led's lighting up on the laptop to show signs off life, charger doesn't have any form of led's to show on or off.

There's a noise coming from the battery power block like a bird tweeting or a single tone of noise when plugged in and switched on, continues when I remove the power cord from the plug for a moment but then stops.

Person who used it wants to take it to a shop and get it fixed but they tried to withhold it last time due to not taking I.D when picking up, long story short their getting a brick through the shop window if they get hold of my items again and attempt to not release them.

So, to save the above issue, do I just need a new charger?

..

Laptop charger connector looks straight and in good condition.

Fuse in the plug of charger looks in good condition.

Connectors on the charger block look straight and in good condition.

Could be the battery or the power supply. Put a meter across the PSU output to test?

Both items are cheap on Amazon

Hi

Have you used the reset button next to the power button?

I have had the same issue with T400s Lenovos and its fixed with a reset
