Sony batteries
I have an old Vaio that is at least five years old. The batteries (2) were obtained within weeks of new. This trip home they're both useless, whereas last summer they were fine. They have had little use as power for the machine, and I can't believe they'd both have such similar characteristics. Are they programmed to kill themselves? And if so, is there any utility to fool them into going again?
The only difference this year is I didn't take the laptop back to the US, so they've had a holiday which my be the cause.
N.B. These batteries discharged themselves at 15% per day - or maybe it was 5%. More accurately, the computer discharged them, as they were fine if removed. I complained bitterly about this and that's how I got the spare battery. They were of course removed while I was away.
