Thinkpad t42 malfunction

I have an old IBM Thinkpad T42 it worked fine for several years. but recently it started malfunctioning. Whenever i shake it the screen goes black and the laptop freezes. If I take out the battery and put it back again it starts up every time. I disassembled it and checked everything but i coudn't find the cause of the malfunction. I think something toutches the metal frame but i coudn't find what does it. Can someone give me any idea what's the problem is?

Instructables Robot Major Malfunction

A couple of days ago, the Instructables Robot had a major malfunction! It had dutifully sent a couple hundred thousand welcome notices, but at the 222,222th message, just starting smoking and foaming at the mouth. It crashed all the servers (on a newsletter day no less!) and just started going berserk. Fortunately, its power supply overheated, slowing it down, and we were able to toss a net over it stopping the carnage.For the time being we hacked together a replacement robot and linked the original Instructables Robot's profile to Robot 2.0. So don't be surprised if you see the new robot around. Our plans were pretty good, but there must be a spark of sentience as the new robot has slightly different tastes.Anyone have ideas as to what happened? We're still not certain where the robot actually came from, but maybe that would help provide some clues?

CD changer in my Subaru is jammed. Can it be repaired?

I have a 99 Legacy. The stock sound system is an in dash 6 CD changer w/ AM/FM and Cassette. It was modded by a previous owner to accept MP3 or other external source via, I think, the cassette circuitry. Anyways, the unit sounds fine, but it came preloaded with 6 CDs that are apparently stuck inside the unit. I'm a bit unsure as to how to proceed to remove them without causing damage. I don't really care about the CDs themselves, just to protect the unit. Thanks in advance, Jim

Help with an xbox 360 controller malfunction

I have 2 Xbox 360 controllers with the left analog stick's dead zone sticking. That is to say that if the joystick is nugged slightly and put down, it constantly registers a small movement in the direction it was nugged until you re-center it. I've tried taking it apart and cleaning it, but it seems the spring inside the analog stick unit is worn out. I've searched google, and the only broken controller hits I got was for the stick breaking off completely from the analog unit. Any insight as to how i could fix this problem, or am I better off trying to make 1 good controller out of 2 bad ones by taking the right analog unit off one and soldering it on the left analog port on the other?

Is the led driver malfunctioning? or am I?

The led driver  http://www.parts-express.com/pedocs/manuals/073-048-parts-express-manual-7169.pdf Im using an arduino to fade LEDs through PWM. The code works on normal rgb LEDs, but i need it to be much brighter. I bought 3, 3 watt, HPLEDs. they are very very nice and bright. but only work with all colors full brightness... i have attached the arduino pins that controlled the normal rgb LEDs to the driver. but this does nothing different then if the pins were disconnected. also if i dont power up the driver and just plug in the arduino it will change the colors of the leds. but it will be just as bright as the normal ones because its only getting 5 volts instead of 13.5. also the color fade cycle acts really weird. not sure what thats all about or why it even does anything just with the arduino plugged in. Does anyone know where to get a decent LED driver? i have looked around for days and could not find what im looking for. this looked like my best option but its not working... thanks for your help. -Rex

how can i find out which part of my charger is malfunctioning? Answered

Hello, I am desperate for help. I have a PWR+ charger for my laptop I purchased a few months ago, today it stopped working. What happened? well the charger still has some function, when I checked it with my voltmeter the output varied from 3 to 6 volts, the little LED on the charger was pulsating, not rapidly, but in short 1 second intervals. Could this be a problem with the voltage regulator? The required amount of power that a normal charger for my laptop outputs is a steady 14 volts, not sure about the current. Now my charger is useless and I don't want to spend another 30 bucks to get a new one, please help. Thanks in advance.

Now when I plug it in windows waits for about a min. then says that new hardware was found. When it's done it says that the device is malfunctioned. I don't know what to do or if that batch file is even the problem. If it is I think that it changed the devices properties into making windows think it is bootable. I have plugged it into my Linux machine but still no dice. It won't even come up there. Oh, and I can't reformat it because it's in a way not there.

Strange problems with the mouse and keyboard? Answered

Must be bad karma for the new year but both my mouse and my keyboard are playing games with me on the PC. Of course they are wireless, mouse is a Logitech, keyboard some very old Aldi brand. After many years of good service they started to fail at the same time. And yes, I tried fresh batteries several times with no luck ;) Here are the current symptoms: 1. Keyboard Randomly keys I press fail to show up although the blinking on the receiver indicates an action was received. When typing a bit faster, and for me that is the two-finger-best-hope method a lot gets lost. My speed is slow enough to make a bad typist laugh in tears LOL In some rare cases I also get totally wrong results, usually somethe graphical character that otherwise need and ascii input to appear. 2. Mouse At times when the keyboard plays up the little rodent does the same. Here it means the pointer disappears or moves in jumps. Also mouse clicks on let's say a tab in the bowser often grab the tab or are not registered at all. It is now starting to annoy me, mainly bcause I failed to rectify this problem in any good way. Only system change in or before the problems started was the usual Windows 7 monthly update, but that came about a week before it all started. To make things worse the mouse uses Logitechs old wireles tech while the keyboard is in a totally different frequency and as said dirt cheap. I also fail to replicate the problem consistently or find a common cause. Funny thing: If used on my old Nexus tablet both perform just fine even from over 5m away. Would love to hear some thoughts on things to try or check... But so you know: Tried the drivers, different ports relocating the receivers and even a rollback of Windows to a state from Nov last year. Everything else connected to the USB ports performs fine. Am at the stage where I even accept weird things to try, so fire up please!

Can anybody tell me how to (further) check my VAWT charge controller for malfunctioning?

I have installed a Flexcharge NC25A-12 Charge Controller and an SE440 regulator in line between my VAWT turbine and its rectifier and the 1000 amp inverter. The turbine and controls charge four Trojan 105, six volt, batteries which are hooked in series parallel (two each in parallel, the parallels hooked in series). The turbine is a heavily modified Lenz-2 (vertical axis, three blades with spring-loaded furling & angle of attack control). It generates 108 to 140 Watts (nine amps at twelve volts to ten amps at fourteen volts) at wind speeds of fifteen to twenty five miles per hour. Nevertheless, I'm not able to charge the batteries. I think the Flexcharge charge controller is stuck, that inasmuch as the controller’s "Multi Function Indicator" function does show when batteries are low, when voltage from the system is low, and when charging is occurring (flashing and steady green light), but has never shown "divert" (to a heat sink). More, I have never been able to get the batteries to hold anything close to their individual 225-250 amp-hour rating. It's beginning to look like the batteries, purchased new originally, have sulfated on account of the charge controller panel not working. I note in using my multimeters that the cable at the heat sink indicates 2.85 volts, even when the batteries are down to 11.9 volts, and when the charge controller is not indicating "divert." When, moreover, an external battery charger (the automotive kind) is hooked in line and in lieu of the wind turbine and rectifier (these being disconnected from the controller, regulator, batteries, and dump load), the batteries indicate full charge on both hand-held multimeters and turbine system voltmeter and ammeter, but the charge controller does not indicate “divert” to the dump load heaters. Any ideas will be much appreciated. Thanks!
