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?

Laptop battery troubles

Follow up to previous question....4yo Dell Inspiron laptop suddenly giving me the old "Plugged in but not charging" routine. Froze the battery for a day but no luck. So I bought a nice new one from Amazon that charged right up and worked for a week. No this one is giving me the same message. Any ideas? Or a place to turn to troubleshoot things? Any help would be appreciated.

Help me diagnose my 1979 Ford Pickup.

I have a 1979 Ford F100, which once belonged to my father. Since he passed away, it's served as a backup vehicle for an array of relatives, and now it's my turn. Yesterday, I got into the truck and turned the key, and I heard a single "clunk" (not a click-click-click), as if something started moving and then froze up. I tried again, with the same result. The next time, I got a kind of whirring sound, like something spinning free. It's a continuous whirring, rather than a series of attempts to catch. Lights and radio work fine. Jumping it didn't help. I didn't try to roll it off, because I'm loathe to leave it at the bottom of the hill in my slighty sketchy neighborhood; I'll probably try that this weekend, when I can get some help. The battery is relatively new. It started easily up until yesterday. [more inside]

Seattle area battery dealers, DC UPS

Seattle area telecom: Can anyone suggest a battery distributor/warehouse that stocks deep cycle lead acid batteries of the type suitable for a DC UPS?

Mac crashing on battery power

I fell asleep a few nights in a row with my Macbook running on battery. I never did this before and now the laptop crashes erratically whenever running on battery, even when mostly at full charge. I assume the events are related, and that this may be analogous to driving your car until it runs out of gas: bad for the car. Advice? Did I ruin my battery? Is there a fix I'm overlooking?

Where can I get something like a Sonic Impact T-Amp?

I used to have a Sonic Impact T-Amp. It was incredible - a great-sounding battery-powered amp with an input for iPod/CD that could drive big speakers at volume. Mine broke and I think I might have thrown it away, which I regret. But in the meantime, is there something similar on the market? A small, great battery-powered amp? I'm based in the UK but would order from the States if needed.

Do you trust 3rd party smartphone batteries?

Do you trust third-party batteries for your cellphone? Specifically I'm thinking about picking up some spare batteries for the HTC Evo, but I've been a non-removable battery phone user for so long that I don't know if I really should stick to the manufacturer's branded batteries or can safely save some money and look elsewhere (like a Seidio, for example).
