Satellite L20: Strange noise from heat sink when the power adapter is purchased

Hello

I own a Satellite L20 laptop and when I take the power cord out of my L20 and power to the battery on a strange sound high tone appears when I put my ear on the heat sink and can be heard normally.

It is never used to do this.
Any ideas?

I don't know if you can hear the sound, as I do, when to do as you described, but this noise is coming from the CPU, when your phone is inactive or sous-travaille.

Have it on my computer Toshiba no as well and everything I read that there is nothing to worry about and normally, you does not recognize.

  • 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 L655 - questions turn on when the power adapter is unplugged

    Hello

    I have a problem with my new Satellite L655. When the power adapter is disconnected and wireless is disabled, the laptop can turn on for less than a second turn it off again. OR turn 'power' and 'Wireless' turns on, but black screen and hd light; After startup bios of 30-40 seconds, the wireless light turns off and hd lights; OR turn on normally;

    Toshiba has changed the motherboard a few days ago, but the problem persists. Update BIOS. My laptop is the only one affected

    Thank you in advance,
    Maurizio.

    Hey Buddy,

    > Toshiba has changed the motherboard a few days ago, but the problem persists
    So have you contacted already technicians again? You must tell them that the problem is still not resolved and it must be another reason for this problem. Then get in touch with technicians again to clarify this issue.

    Have you connected external devices while laptop is turned off?
    -Online if yes remove each of them.

    Load default settings in the BIOS?
    -Online if it is not this. Enter in the BIOS, and then press the F9 key to load defaults.

    Otherwise, it would be time to service as I have already written. It must be a nuisance material

  • Satellite A300 may depend on from when the power adapter plugged

    Hello

    I have a problem with my Toshiba Satellite A300 when the laptop is connected to the power adapter I have no possibility to turn it on, it's only 2-3 seconds once it comes down.
    When Toshiba is enabled with the battery power and I tried to connect the adapter it also goes down.
    I have no problem with the charge itself, but only with working with AC adapter.

    Please help me what can I do with this problem, does anyone has similar problem?

    Hello!

    For me it sounds like a hardware failure of the motherboard if the AC/DC adapter is plugged and the laptop is turned on

    I don't know but how best to m would be if you go to the authorized service provider nearest with the AC/DC adapter. Technicians can check your laptop and swap the motherboard if it of really necessary. The guys are very friendly and helpful!

    Here, you can search the nearest ASP:

  • His acute appears when the power adapter is plugged into satellite

    Hello

    My laptop is four days old, but when I use it and the power adapter is connected and provide electricity, a steep, low sound volume is issued from the fan area. When I remove the adapter it disappears usually, but sometimes intermittently returns in the form of a stuttering occasional, typically when I use many processor programs.

    I also noticed that, if the sound is not present and yet I increase the brightness of the screen in the properties of the TOSHIBA power saver, he'll be back with a vengeance. In addition, the power supply makes the same buzz, but at least I can sit several feet from it.

    Can someone therefore please tell me if this buzz / your electronic is normal, or if there is something I can do to prevent it being issued?

    Thanks for any help.

    [email protected]

    Hello

    I think you should contact your dealer / ASP with this problem. It seems to me that there is some sort of component inside the PC that generates this noise when the processor speed is high.
    Also if the power adapter is buzzing, you must show this to them as well.

    It does not seem right that the unit should behave like that.

  • HP Pavilion 6500 goes out when the power adapter plugged

    My Pavilion 6500 (specifically dv6623cl) turns off when I plug in the power adapter. If I plug it in, then turn on the laptop, it automaticly turns off before loading windows. If the laptop is already started, and I can plug the power adapter, it immediately turns off. I can charge the battery without any problem, also while the laptop is turned off, but as soon as I turn it on with the adapter plugged it stops, I checked the battery through HP battery check and he said its good, he is holder of a charge very well and everything, the only change made to the laptop hardware wise was an upgrade memory I had no such problems until the upgrade of memory, but I do not see how it would affect the power on the aspect, in order to make a system restore, if ever, I need, the poweradapter must be plugged and theres other system functions that require the adapter complete, it is a question that must be corrected

  • 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!

  • Satellite A300 stops when the power adapter cable

    Hi people

    When I connect the power cable for my toshiba satellite a300, it stops immediately. I can use it on battery normally without any problems.
    When I boot in safe mode, it works fine without any problems with the AC adapter plugged into the laptop.
    Operating system is Windows Vista
    What is the reason? What can I do to fix this?

    Thank you

    Can you use it for laptop with AC power only when the battery is removed?
    If so, boot up your laptop and when the operating system is loaded to put battery inside, wait a few minutes and disconnect the power supply.
    Plug it in again and let us know if the same thing will happen again.

  • Trackpad and usb mouse stop temporarily when the power adapter is connected

    It is a very weird, crazy question. It began to happen today.

    Introduction: I installed ubuntu since 2008 in this laptop from version 8, now I installed 11.04. My brother has the same problem since a month there is around. It has the same model of laptop (DV9000 HP), but Windows Vista computer.

    The problem: mouse freeze random by 1 or 2 seconds, the two mouse pad and usb mouse attached. When I unplug the AC adapter, mouse works well immediately.

    Indices: I forgot my adapter in my apartment this week, and I got my brother to work here (the House of my parents). And another hint, I used a power adapter for cars, today give it a 19, 7V instead 18, original 5V AC adapter. My brother also use this car adapter.

    Hey, try to get the other original AC adapter. My laptop has become normal when I got my power adapter. See me first post

Sometimes the charging light does not shine, but the battery is always also load into windows. Its 89% since the last 2 hours. As soon as I unplug the charger, the laptop everything turns off and will not start without it. I can't even contact since my laptop acer support is not under warranty; /. I just did not notice before because my laptop is usually plugged into my office. Please need help as soon as possible. THX in advance

    This usually means that the battery is dead, is disconnected, or may have pushed the button 'disconnect' battery on the merits of the case. You might have to open it and remove the battery and make sure that the connections are well connected and put into. If this does not work, maybe need/want to buy a new one, like being able to enter the computer directly instead of the battery can damage internal parts over time.
