• M40 turns on battery

  My Satellite M40 225 lights on the battery. When the power button is pressed, the power key wrapping appears in blue, so everything is dead.

  When the power adapter is plugged in, the powers of calculation to the top normally, "remaining battery" is given as 100% standby Toshiba power settings, and the battery at the front of the computer light appears blue. So the battery turns out to be paid.

  I've had the computer for a few weeks. Power a battery worked fine until recently and I see no reason for that change.

  I would be grateful for any help. Thank you. Mike.

  Hello

  AFAIK if both parties (battery and adapter) are connected to the device, this can damage the battery or decrease the battery life. You must always remove the laptop battery if the AC is plugged.
  In your case, I propose to remove the battery from the camera for a short period.

  But in my opinion if it doesn t help I guess that it s something wrong with power electronics.
  In this case your laptop needs a services.

  Good bye

• Equium A200-1V0 died

  Hi guys and girls

  I have a Toshiba Satellite A200-1v0 and its dead, does not start, no power light. Before that happens the charger light turn on and didn't go out even when the power is off I had to take the battery out to kill light when I put the battery in it has worked very well and with the power supply as well.

  But now it won't come at all. Can anyone help with this problem I o year engineer so I can use a multi meter I ve checked the internal fuse on the motherboard and they seem to work but now I m lost in the place where to check. I ve also checked the PCB continuity and that s ok too.

  Could it be just the power switch pcb edge. ?? Help, please.

  I am not a technician, but to me it looks to power electronics issue.
  What you need is the exact electronic diagram of motherboard to see what may be the problem.
  Problem is that the maintenance manuals is not a public document and you can't find it online.

  Maybe you should try to contact the nearest Toshiba service provider. Talk with them. If anyone can help service is the right address.
  Here, we can just discuss and try to offer some opinions, but I do not think that anyone here can say with certainty what can be the problem.

• Satellite A300 turns off

  Hello

  I have a Toshiba Satellite A300 (for about 3 years now) and tonight he turned off his car. It would be most time cause of overheating and would finally restarts, but not tonight. It simply displays an icon of the battery at the front about 6 times - then nothing. I tried already out the cord of the battery and the charger, press the switch & 30 seconds and it does not work.

  It might be useful to mention that for a while now, when the charger is unplugged the laptop would turn directly to the output.

  What I need to know is, it sounds like I need a new charger or a battery?

  For me, this looks like faulty power electronics.

  Can you use laptop on the power supply only when the battery is removed?

• Satellite A10 will be no boot up - blink code

  OK at first, I was getting the orange light flashing 00000010 (40 h) and after playing, I now get the light green DC but when I press the power button / flashes of screen for a split second and made light of dvd but NOT power on light or power. I wiped the system down to the Board of Directors and cannot find that dry points or what would resemble any problem.

  Here is the link to the left conversion in case someone is trying to find.

  be sure to read the flashing lights back.
  mine was 00000010 it is 01000000 = 40 h

  Any help with my problem apppreciate anyway be great.

  Hello

  In my opinion there must be something wrong with the power of power electronics, as I suggested in your other display.

• Qosmio is plugged in but not charging

  Hello

  Yesterday, I spilled my shake on my laptop... I managed to open it clean and everything works well EXCEPT MY battery, it is at 0% and every time I remove my AC my laptop turn off, then, what do I do is my battery died or my charger connector?

  And what do you recommend I made m from Chanute, Kansas. I tried to call the Toshiba support center, they said that my laptop is still in warranty but they can't help me because I can't drop my laptop to Toshiba service!

  Weird assistance):
  Thank you

  It is clearly defined that is covered by the warranty, and what cases can be repaired for free. Certainly, your question is not covered by the warranty. If there is mechanical damage caused by the owner he will not be repaired for free. Service box help m from you, but I'm afraid you have to pay something must be changed or repaired.

  On this virtual path we cannot say with certainty what the problem is here, but all electronic power supply must be checked. To be honest, I can't imagine that the battery may be defective.

  Anyway, what you can try is to get the new battery, test it and if the situation is the same it must be a problem with the power electronics placed on the motherboard.

• Satellite 2430-301 uses battery plugged

  Hello!
  Sometimes, when executing programs from CPU, my battery begins to discharge up to zero, while the Toshiba Energy Manager even acknowledges that the laptop is plugged. After leaving the program (game), the doesn´t of the battery starts to charge, but the laptop won´t, turn off because it gets the energy cable s.
  What harm there?
  Thanks for the help!

  Hi Hendrik,

  It is possible that your power adapter begins to fail and cannot provide enough power for your laptop to meet any demand particularly heavy (such as using heavy graphics games). This will result in the power electronics from your laptop to battery power.

  Sometimes, disconnect and reconnect the power cord will return things to normal.

  Kind regards

• Equium A60 will not work without battery

  Help!

  My A60 will work on a full battery but when I put the power cord in it, it still works on the battery even when he says he gets the sorce of power and count the percentage until he spends.

  Then I let it charge a big short TI. I got a new battery still, a unit of power too much and it does as an update of the bios.

  It's like the charger is there for the battery.

  I agree with Richard. Perhaps is there some problem with electronic supply power. I think that the technicians can run test or some diagnostic programs to verify if really power electronics is damaged.

  Generally electronic power should recognize the power running and automatically turn off battery power and start charging the battery.

• How to use Labview to control the motorized turntable?

  Hello

  I am new to Labview and do a project that requires the use of labview to control the motorized turntable (XYZ axes). I need to use the Labview programming and have no idea at all. Need help, thank you very much!

  Lei,

  Everything said by others is correct and to do because they describe, at a given time. But I always approached these projects of motion control first by looking at the 'motion controller' (I hope you have a) and 'drivers' (what you need) between the computer/LabVIEW and engines decide what communications will be required for these devices and get an idea of the syntax of command and the language to use with them.  In some cases, the controller and the motor driver are integrated in a single unit. Heck, in some cases, they are even integrated with each engine.

  The motors can be the stepper motors or perhaps servomotors.

  In the case of drivers stepper (devices that provide power electronics to run the engines), many of them are run using only two control signals for digital called 'step' (a pulse train) and 'direction' (high-low level) and if it is possible to generate directly with the PC, it's an order of magnitude easier (if you have not already a library of available motion control to manage the generation of these signals and) the execution of the stepper motors) of having a "Motion Controller" between the PC and the "motor".  Engine drivers step by step usually can be configured that current engine and the size of the stage and sometimes for the other plus-moteur/driver-parameter setting. The configuration of these can be made with jumpers, switches or, for some drivers, with orders ASCII on some sort of port of communication, but in general these are values you download the installer once at the beginning and then never touch again if you do not need generally to have a full time available on their change communication path.

  In the case of the actuator drivers (once again the devices that provide power electronics to run the engines), many use a +/-10V control input analog signal, and, again, while it is possible to generate the signal directly with the PC hardware, a separate axes controller is usually much simpler and more robust.  In the case of a servo system, there is also a signal back to an encoder or resolver attached to the engine to be used by any device will exercise the motion controller in the system.  There are once again associated with the driver configuration parameters (and controller in this case, since it is part of the servo feedback loop) which must be configured at the start but once set up properly, they rarely need to be changed again.

  A movement controller which is separated from the PC often manage several drivers, and can often coordinate a movement between them. It will load the rise up/down of the engine speed as that changes. It will be followed by position of each motor. The servo system, but it will take the feedback signal and use it to adjust the speed/position/torque of the engine. The motion controller also deal with race and home or index of signals is usually on most lines of movement and provide information of the State of the switch to the PC.   To run the motor controller is then just a matter of chaining a set commands of (usually ASCII) to indicate how fast to run and how far to go (and direction) and by sending a command "do it." Then, ask you to keep track of the status of the process and the States of the switches.

  In many cases the builders of controllers of movement are a primitive way to communicate with the controllers of a PC with no additional software other than what they offer. With this you can at least have an idea of how different the controller commands and responses they produce. That you can start to build sequences of commands to perform the actions you want.

  You can then add LabVIEW to the mix and to understand how you can get it to send sequences of similar orders on the paths of communication that are available and respond intelligently to the information it receives in return for motion control.

• Tecra 9100 does not supply power to the top

  Hello

  I got Tecra 9100 laptop computer and you have a POWER PROBLEM.
  Basically, it got stuck at the start of the OS and I was unable to click or move the mouse to do something. So I held the power button to turn it off. I do not turn on again entered game coz I had to go somewhere.

  So when I tried to move THE next day and he won't power upward. I can see a GREEN LIGHT but can not hear any CPU, the FAN, the monitor or the hard sound. When I connect to the AC adapter, I can see the LOAD LED but nothing else seems to be powered.

  I also tried to replace the memory Module, but still won't power upward. I guess that the motherboard does not have to be ABLE so nothing is turned. But the one thing that I do not understand why the POWER LED on (GREEN LED) is on, unless it has the power source.

  Can someone tell me what I need to do?
  Help, please

  Thank you

  Hi Sonia,.

  I suggest that you try to remove the battery and power supply so that all power of the laptop is turned off. Reconnect AC power and try to turn on the laptop. If it works, then re-install the battery. I think that the electronics of power sometimes get "stuck" and this procedure usually receives smooth them.

  If the unit still does not power on after having tried the above procedure, then I suuspect there must be a problem of internal material in which case you must take the device to a partner of Service authorized for rectification.

  Kind regards

• Question about Satellite A30-power adapter

  Hello

  I own a laptop Satellite A30 and my charger just died. I have looked on the internet to buy a new one, but can not find the same model of the same brand (delta ADP-90FB REV electronics. (E) and having trouble finding something on the site Web of Toshiba.
  I found some Chargers compatible with laptops Satellite A30 on another site, but they are quite expensive (about £55). Another less expensive option?

  Thank you

  Hello

  Believe me: it s better to use than stuff unnamed original equipment. On the one hand, you win money and if your machine is broken due to a power adapter that gives your machine
  a wrong voltage or whatever.

  I had a great experience with my tecra 8100 a few years ago:

  My old AC was broken, so I bought one in a store, which has been declared as "corresponds to 100% and blablabla".

  Cost: $ 37

  After a while my machine freezes sometimes and for a day-> no boot.
  Then I gave my machine to fix after they have made their diagnosis, they asked, what sort of AC, I used. Heh? They explained to me, I used the AC adapter was not a constant voltage,
  If some capacitors smd-says 'goodbye '.

  You can save money, but give you him another side, believe me.

• P10 504 does not and will not power work

  Hello

  I'm having difficulties with my P10-504. I plug my charger to the rear of the unit and nothing happens. No lights come on at the front and no charge or turn on the power to the laptop.

  I have some charge left in the battery and it shows that the computer is operating from battery (battery) power and no power.

  I checked to make sure that the charger works with a voltmeter and it seems fine.

  Is someone can offer a soloution for me?

  Thank you

  Adam

  Hello

  If the adapter works correctly and is not broke so the only possibility is an electronic supply failure. You can't solve this problem by yourself.
  I recommend you contact the ASP. He must check the portable electronics

• question iMac i7 to power 2011

  Greetings,

  I think I'm having an interesting eating problem and I hope that someone with an Apple hardware experience could read this before blindly, I replace the power supply (and spend money, I don't).

  I have a 2011 27 "iMac12, 2. Model A1312 EMC No. 2429, iMac Core i7 3.4 GHz. 12 GB of memory running 10.9.5 with the latest updates. 8 GB of third party RAM and an SSD of third with OWC temperature sensor cable. Fans will work perfectly and normally respond with this SSD and cable.

  This is a long post, but I think I describe an interesting problem. So read on if you want. Otherwise - thanks anyway.

  I am an electronics engineer and use Macs for a long time. But don't have the inside scoop and experience with the power of the iMac and logic boards, maybe an Apple technician will see this and be able to answer a few questions I have.

  This computer has been great for years of work but began acting strangely in the last week. I noticed that he wouldn't wake up from his sleep, and then I noticed during active use would block after about 45 minutes or an hour or two.

  Sometimes, I'd get the (pizza wheel) spinning wait cursor when in the finder, then for each open application that I would try to activate it once that this started happening I couldn't recover from it. The box to force out would not come to the top. Only a (switch) forced shutdown and restart would bring the computer to life.

  When the problem occurs, I'd get the spinning wait cursor, no response from the keyboard. Windows remains visible on the screen can be moved, but otherwise don't would not respond and applications would hang.

  When you run properly, the OS and applications behave normally and appear to be catchy as ever.

  I did a lot of troubleshooting. It felt like a problem of material for me.

  I first turned off the Bluetooth, then removed all external devices and connected a wired keyboard and mouse. The problem occurs when you are logged in different user accounts and not appear related to a specific application. When she fails the computer stops responding on the network as well.

  I started in safe mode which did not help.

  I ran after each failed disk utility and reboot. The third internal SSD seems fine and passes check and permissions check every time.

  I did a virus scan. No detection.

  I ran the diagnostics of material. Usually happened, he only missed once during the test expanded memory after an hour. I then removed the 8 GB of RAM third leaving only the original Apple 4 GB of RAM installed. The successful test material. Sounds like bad RAM?

  No, Frost continues with only the Apple installed memory. I think the hardware test failed, because the power supply problem would happen after a time anyway.

  I turned off the screen saver and sleep so I could see the contents of the screen when it failed and during that time, tried to use the machine for a normal job. I have to prepare taxes and screen 27 "is very useful at the time so I can open lots of windows. But the computer crashes as I get into my work.

  Finally, I pulled my copy of HardWare monitor (v4.99) and noted the various sensors. I noticed that the voltage sensor shows two voltages, 12 volts for the MXM graphics module which seems stable and right around 12 volts.

  The other specified voltage is the provision of CPU. I guess this is supposed to be 1.2 volts. But it varies - much.

  The offer varies 1.2 Volt to as low as 0.87 volts. It must be the way out of the standard if it is supposed to be a supply of 1.2 volt.

  So the first question, is that really supposed to be 1.2 volt? I don't know about you, but this makes sense to me.

  Then the provision of 1.2 volt regulated on the power Board or regulated on the logic board? In other words, replacing the power supply would be an interesting test?

  But here's the interesting part: the voltage INCREASES to 1.2 volts and becomes stable if I give compliant to do computing. I started to run the chess playing program computer vs computer. The tension immediately stabilized at 1.2 volts and looked good! I was expecting to fall!

  Who knows what is happening with this switching power supply? The increase in workload may actually it wrong in appropriate regulations. That being the case, I'll keep the computer play chess in the background while I work on my taxes that I monitor the voltage and see if this prevents crashes until I can replace the power supply, or something else.

  Thanks for reading.

  Greetings,

  I solved this problem. It was pretty weird. On the way, I discovered that it is normal that the voltage of the CPU has to vary, it is a feature of the processor Intel 2600 for energy savings. I discovered that gel that happened exactly one hour after re-powered to the top of my iMac. Exactly. It was too weird. It turns out that my Crucial SSD drive has a bug in the firmware that comes after 5200 hours of operation and then every hour thereafter, requiring a power cycle to get it going again. The problem is described here. I'll replace the SSD with a larger (from another manufacturer!) rather than trying to update its firmware.

• HP pavilion elite hpe-035sc: power supply wattage

  Hello

  I have a hp pavilion elite hpe-035sc

  Product number: VS311AA

  I7 870 2.9/8 GB ram/500 GB

  power supply: 460w delta electronics dps-460 DB A (it has a connector 6 power pins)

  I recently added an asus gtx 550 ti and it worked

  I'm worried about the power supply, do you not think that it is enough

  checked the power supply and I found:

  max power: 460w

  power combined 12va + 12vb + 12vc equal to 385 W (it does average?)

  THX

  It should not be any problems with the installation at all. Just do yourself the favor of not not overclocking the card.

  Delta POWER supply has enough good specs for a mainstream card like the one you have installed.

• Novice probably stupid power supply laptop power issue

  I have a Tecra A4 and I have what is probably a silly question.

  When the battery is running down what to cut first laptop before connecting it to the power of the transformer or can I just plug the / click on the talk button while the phone is still on?

  Hi Bill,

  It is completely safe for your laptop to be plugged in, while it is still running on the battery. internal Electronics will take care of the passage back to the mains and your laptop power management software will change based on your settings.

  Normally, it is recommended that you remove the battery (when fully charged) when running on the current, although generally, I leave my just in case a power outage.

  Kind regards
