What does this in my tray mean?

Safely Remove ST325031 0AS SCSI DISK DEVICE - DRIVES (D:, C:)

Also my gadget guy had to come out here the other day.

The problem: My CPU would come on but not the monitor. It wouldn't even come on. My initial thought was, a shot v-card. But when the guy got here and opened up my girl here, he did something to the battery.

After he left, I noticed that a select few sites were taking forever to load, even with my dial up connection. And no, they didn't take that long before. When I say long, I mean long; more than being on hold wth Verizon long.

My question: If this happens again, will my machine need a need battery, or to be replaced, or what?  I have had this machine since march of '08.

Thanks!
