Hello, I'm Mark. I damaged my lower back as a teenager, and It's slowly getting worse. I'm 62 now and live alone and get by on benefit payments. I rarely leave home anymore. If I do, I have to walk with a stick.

During the day, I spend most of my time in front of my laptop. I have a 2017 MacBook, and my laptop's battery is dying. I constantly worry that when my battery dies, the laptop will be dead, too.

I've already raised some funds but I'm not there yet. Please help me buy a new laptop battery.
