Some of you may have seen this in my tweetstream over the weekend:
Now attempting to fact-check one of the more bizarre theories I’ve heard lately: a dead laptop battery benefits from a night at 0 degrees.
Motivation: after two hours of operation with the power plug in place, battery power, according to Toshiba’s power meter, remained at a solid 0 percent.
So I slid the battery out of its slot and into a Ziploc bag, and set it in the freezer for fourteen hours. I gave it three hours to warm back up, shoved it back into the machine, and plugged it in; the trusty orange Charging light came on.
When the orange light turned to green, I disconnected the power cord and booted up the machine. After four minutes, I checked the power meter: 97 percent.
Half an hour later I was down to 84 percent, which is consistent with what I was getting out of this battery six years ago. I shut it down at that point; over the next few weeks I will be draining, refreezing, and recharging this battery, to make sure I’m not dreaming.
Variations on this instruction are all over the Web.
Update: Follow-up report.
