  Any help will be greatly appreciated.

  Hi aloum,.

  (a) what kind of mouse you are using?

  (b) the left button of the mouse seems to be stuck or it does not meet the click? This only happens with certain applications?

  Step 1: Test the mouse on another computer or another mouse on the test computer

  To determine whether the mouse or the computer is defective, follow these steps:

  1. test the mouse in question on a system that works, you know. If the problem appears to follow the mouse, you may need to return or replace the mouse.

  2 test a mouse you know is working on the computer in question. If the problem seems to stay on the computer, then the problem is most likely related to the software.

  In regard to the battery not holding charge

  Battery problems are often associated with the battery itself. If you encounter this problem, contact your mobile PC manufacturer. If you purchased the battery separately from the notebook computer, contact the manufacturer of the battery.

• Satellite Pro A200 (PSAE4E) - power off when the AC adapter is connected

  I bought this laptop for my wife about 2 years, since about 6 months ago, that the laptop was randomly shut off without warning, this only seems to happen while the power supply is connected as well.

  I have read several other posts on other sites with people having similar problems.

  There are various suggested corrections, you must disable the duel core in the bios so that it works only on one heart and he spend dynamic low for fans. I did this about 2 hours ago and touchwood not a single switch off again. This however is not an acceptable solution, there is obviously much more slowly.

  Another suggestion has been updated the bios, I downloaded it now but am very worried to run it, this laptop can stop at any moment, lasting from a few minutes to a few hours. If it stops while updating to bios, I doubt that it would be good news. I don't want to make it work on the single core for the rest of the day/night to see if its stable and then go for it.

  Before that, can I make a call to the toshiba helpline, I read on the forums that this is as well a defect of design within the laptop and there's a reminder of some of the laptops in the Canada, I do not know how it rings true but still a concern to read and might be unacceptable to the owners of the A200.

  Others have advised that it is an overheating problem, it's that I reject, I running SpeedFan and showing a stable 47 temp and it allows to switch off the coast immediately when turned on, yes it could be due to dust build up, something I checked and cleared, it did not a difference for the frequent switch offs.

  Im not too well why it is only when the power supply is connected, I have not tried a different PSU, but those who have had the same problem try this and it has not solved the problem.

  When I unplug my power as well the battery seems last mabye 5 minutes at the most.

  Overall, Im very unhappy all this, toshiba is a brand of 'high' where you expect better quality and pay for it.

  If anyone has any suggestions please let me know, would be also good to hear talk of toshiba support on the issue.

• Manufacture of extreme dual band 802.11 airport "buzz sound" when the power supply is attached

  Hello

  which is very probably wrong with my Airport Extreme?

  My Airport extreme dual band 802.11 done "buzzing" sound when the power supply is attached. The sound disappears immediately when power is disconnected and begins as soon as you connected again. It started two weeks ago, and it's really annoying.

  THX,

  Laura

  Most likely, the question is a bad capacitor in the diet. These can fail and are, unfortunately, not serviceable by the user... unless you have experience with electronic repair. You can try Apple, but chances are that you will have the best chance to get a replacement from another source, such as Impact Computers & Electronics or eBay.  I'm sorry.

• Satellite Pro L20: battery not charge when the power adapter is connected

  Hello

  all advice appreciated.

  I had a Satellite Pro L20 for about 18 months. Recently, battery does not charge when the power adapter is connected. The battery light starts yellow (which means more liberated, I think?), then will both green, the machine sat for awhile. However the ACPI often said that AC is "offline."

  There are two recent occurrences that coincide with this problem, I try to eliminate:

  1. my friends rat chewed by the feeder for pets! Power is Mobile OK insofar as he fled sector - the rat seems to have simply chewed by the outer cover (I see some threads, but I think that is just a shield, although I'm not an electrician).

  2. I put the laptop in hibernation for the first time. That seemed to mess up the system a bit, which was what initially drew my attention to the problem. This question is a bit complicated because I'm under Linux (Xubuntu).

  I updated the drivers etc from windows when I bought the laptop. Never had any problems until now and have been running linux for centuries. Also, I have mainly the laptop the power supply turned off, but do not remove the battery (is that really a problem these days?)

  I obviously need to replace the adapter, but is - it is likely (and how I can check) that the battery was borked until?

  see you soon
  Chris

  First, please check if the other are lit.
  If the AC led and power led are on the adapter sector is ok and it provides the power to the laptop.

  > The battery light starts yellow (which means more liberated, I think?), then will both green, the machine sat for awhile
  If the battery LED is yellow, this means that the battery is not fully charged and if the Green led changes then recharging is caught and the battery has been recharged.

  So I really don t see any problems with the charge process.

  Maybe the battery is old and so you cannot use it for an extended in such a case only the replacement of the battery could help.

• Satellite M105-S3074 - blue light flashes when the power supply cord plugged

  I have a Satellite M105-S3074 that when I plug in the power cord the blue left flashes just light and unit will not feed. When I unplug it from the laptop all lights go out and it is will not help here please

  Thank you

  Hello

  This means that your mobile doesn t boot with AC/DC adapter and AC/DC adapter too?
  Really strange what s

  Have you tried to remove the battery and the AC adapter? If you remove the two you should an hour and then reconnect the two. Maybe it will work.

  If this isn't the case, it seems to be a hardware problem. You must contact an authorized service provider, you can give them a call to speak to a technician.

• Satellite C660 - 115 WLan connection only works when the power cable is connected

  Hello

  A few weeks ago, I bought a Satellite C660-115. I want to surf the internet anywhere in my house without any son/cables.
  On the first day, I had this problem: when I disconnect _power_ cable, the wireless connection will stop working.

  The Web page on my screen will always be there, but a new page loading is a problem.
  It is sometimes useful to recharge (by pressing F5), - sometimes not. It is always useful to "ip address of repair", but not for long.

  The only solution is to atach regardless of how much power the battery has still the power cord.
  When I do, it is no problem whith the connection at all.
  I went back to the store where I bought it, they related to their own wireless network and they have had the same problem after a few minutes. In the shop too attach the power cable solved the problem.

  So the problem must be in my lap top, not in my network (modem or almost).

  Doesn't this all seem familiar, and if so, how can I solve this?

  I hope that my English is understandable, I live in Holland.
  Thanks in advance!

• T400s display flashes when the power cord disconnected - how to fix?

  Just got my T400s a few days previously and very happy with it!  But one thing that bothers me is when I unplug ac power chords, screen goes white, then back on. The same thing when I plug ac power chord back in.  I posted this question in another forum (NBR) and someone replied that this problem has disappeared after a clean install of the operating system without Thinkpad utils.  So, it has something to do with one of the utils.  BUT I can't find anywhere how to disable this behavior.  Please advice!

  Binaryspiral solution worked for me - thanks.

• Compaq 6910p - wireless adapter turns off when the ethernet cable is connected

  Hi all

  Then, when I plug in an ethernet cable (connected to a router), my wireless adapter turns off.

  He immediately turns on when I unplug the ethernet cable.

• Satellite A300 stops when the power adapter is connected

  Hello!

  Yesterday, I bought a new Satellite A300. I plugged it in, worked some time with her and then I decided to stop it while it was plugged.
  The computer has stopped working, but in a few seconds, he started alone.

  I tried to do it while it was disconnected and there is no problem, but when it is plugged the problem persists.
  I would be happy if someone can help me!

  Thank you very much!

  I would try a BIOS update. You can download it here: http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp
