Where can I buy a Lenovo X220-compatible charger in DC today?

Right now I'm at the airport, waiting to fly into DC, and just realized I forgot my charger. I'll see what I can pick up at my layover, but I would like to a) not fry my laptop and b) continue to use my laptop. I would like to buy the charger after checking into my hotel. I will not have a car. Relevant facts: 1) The X220 is the small Lenovo Thinkpad (not touchscreen.) 2) Staying in Dupont Circle 3) No car

NiMH Battery Chargers that work

I have a good mix of AAA, AA, C, D & 9V rechargeable batteries. Are the mindblowingly-expensive Powerex chargers the only game in town for getting a decent charge, or are there other options? [more inside]

Nexus 7 battery takes forever to charge

I have an 8-GB Nexus 7 that's about a year and a half old. Its battery life seems fine, but the actual charging takes an unreasonable amount of time. When it was new, it charged in about 2.5 hours; last night it took 7 hours to go from 30% to 60%. I'm using the adapter and cable that came with it. Is there anything I can do to make my device charge faster?

MacBook Pro Battery Life Question

Greetings - I "inherited" a MacBook Pro last year. It was a Apple MacBook Pro Core 2 Duo 2.4Ghz from Spring 2008. So it was 4 years old when I got it and I was told that the battery was dead and as long as I kept it plugged in, it worked fine, however, I would need a new one. So last year, I purchased a new battery and installed it. However, I am still noticing that the battery life is horrible. It seems like when I am using it to type a document or check emails and surf the web, etc, I literally can watch the battery drain. I would assume that it might hold a charge of about an hour and a half maybe? Is there any way I can "test" it to see what my actual battery life if? To ensure there isn't something else going on? Any suggestions would be helpful. Thanks,

Laptop / Netbook that runs cool and has long battery life

Interested in a Netbook or lower power laptop that runs cool (doesn't require external cooling like this) and has long (6-8 hour) battery life. Would like to run Windows 7 so Chromebook is not a good candidate for me. And of course want to come in around $200. I know there a lot of candidates here but would really appreciate user's real life experience. Thanks.

Is it wise to replace the dead battery in my MacBook?

I have an older MacBook I use when travelling (four or five times a year), and then the odd occasion when I am away from my office desktop. The battery on the MacBook died a few months ago, and I am guessing partially because I haven't been using it frequently enough. I am hesitant to replace the battery, figuring the same thing will happen again, is that right? Is there a downside to not having a working battery on the computer itself? And lastly, is there a problem with leaving the dead battery in the computer?

Is my iPad 2 up to the job?

Is my ipad2 up to the job? I have to give the same hour-long presentation in three separate sessions in one day. I am planning to use Keynote on my ipad2 attached to a projector but I'm worried about battery life on the iPad. Does anybody have experience using their iPad in this way? I will of course, turn off every battery draining thing I can find. I could also switch to my iPhone 4S if I had to, I guess. Will I be okay for three presentations?

Help me bring my crappy keyboard back to life!

I'm trying to resurrect an old Casio CPS-85 88 key keyboard. When it was given to me, the power jack was cracked, so I desoldered it and soldered on a new one. No luck; I can't get power (even with a different power supply). So I'm stuck running off of a lot of D batteries. As using D cells is both wasteful and expensive.is there any way for me to rig an external power supply to the battery terminals in a safe manner?

drain on Ford F150's new battery?

Help us diagnose our Ford F150: what could be draining down the (new) battery overnight? We're suddenly seeing apparent battery drainage in our pickup truck, a 1994 Ford F150. Though the truck starts up fine, the dashboard battery gauge reads low immediately upon ignition, the windshield wipers are sluggish, and the dashboard lights are dim. We thought the old battery was likely dying, so we had it replaced with a new battery... but that hasn't solved the problem. [more inside]
