My landlord is charging us 150 for bad wiring and wiring shortage and we had left it good and working I think she is just wanting my security deposit

I decided I wanted to move from my old place due to moving away so I gave my landlord the 30 day notice,I left everything clean and the day came for her to come see it she told me she wanted me out by then which was a friday . I texted her if she was coming she said so till Saturday I had all my things moved out and I knew everything work like electric wise and water so I shut it off before she want because if she want on Saturday the water wasn’t on till Monday and they were going to make my bills go higher fast forward she came and said everything inside was fine and if I could take of the weeds because she left it cleaned I remember she didn’t clean it but I didn’t take pictures so I just did it and sent her the pictures after 4 days later she called me saying there was a wire shortage because when I moved I installed camaras and I messed it up but we didn’t we went to go look and indeed fixed some things and we never used the lights I don't have room for more but there is more
