Satellite L500 is OFF and green light flashes if connected to mains

HELP!!
I have a L500 which does nothing apart from the green light flashes when the power cable is plugged in but does nothing else

Hi
What indicator do you mean exactly?
The DC indicator (first from left) glows green when the power is being correctly supplied from AC adaptor. If the output voltage is abnormal or if the computers power supply malfunctions this indicator will go OFF.
The other indicator (power led second from left) glows green when the computer is turned on. If you turn the computer off into sleep, this LED starts flashing amber.
Furthermore if there is a memory malfunction the Power LED will repeatedly flash
On for 0.5 sec and off 0.5 sec
If there is an issue with slot A the LED flashes amber twice then green once
If there is an error in slot B, the LED flashes amber once then green twice
If there is error in slot A and B the LED flashes twice amber and green.
But if the power LED flashes only green, I assume there is a motherboard problem.

  • Satellite A500 - Battery light flashes when connected to mains power

    Win 7 Satellite A500 PSAM3A-03P00E.
    The battery light flashes when connected to mains power (intermittent fault), when I unplug mains and re-connect flashing stops and battery (high capacity) continues to charge.
    Also when battery light flashes the key board back lighting stays on when it should blank out and if the back lighting is off and the battery light starts flashing the key board back lighting doesn't turn on, all other functions seem to work fine.
    The battery charges and holds charge as it should (when light flashes battery doesn't charge).

    Hi
    Did you notice this issue from first day of purchase?
    Theoretically it could be possible that your battery starts to malfunction
    At the other hand an electronic issue might be possible too
    However, try this:
    Remove ac adaptor and battery. Then press and hold power buttons 30 sec long.
    Then insert the battery and connect AC adaptor again does it helps?
    By the way: is BIOS up to date? If not, perform an update.

    All fixed, the earth contact in the power jack was bent down allowing intermittent contact and limiting current. I bent the contact back up to where it should be and all is good.

  • I have macair bought 2009. Bluetooth connect with mouse and keypad not working. It used to work. Batteries are good. Green light flashes on each device, but no connection. Any suggestions to help me here? Thanks.

    Dear Community,
    I have a macbook air bought new in 2009. Since 2011 I only use it occasionally as I  now mainly use my iMac. The mouse and keyboard that came with the macbook air used to work fine with bluetooth connection to the macbookair, but now they don't. The batteries are good. The green light flashes showing it is seeking other bluetooth device to connect to. But they wont connect to my macbookair. What could the problem be? Your help would be much appreciated.

    Thanks for that. Yes I checked that already and BT enabled. Yes, external keyboard. But I just moved the computer to different part of room and bingo the devices paired and connected. So problem now solved. Thanks for offering your help.

  • I tried to activate my new iphone 5 through itunes without a sim card, and my mac air crashed. red and green lights were both flashing but I can't get the computer to power on

    I purchased a used iphone 5 on ebay which a.) had no sim card, and b.) still had a passlock code. tried to activeat the phone via itunesbut as soon as I plugged the phone into the mac, the red and green lights began flashing the the computer then shut down, and will not power back up. Any suggestions??

    Return the defective phone to the seller, and hope that it didn't burn out your logic board. Make a "Genius" appointment at an Apple Store to find out whether it did.

  • How can I turn off the green light indicator on my AirPort Express?

    How can I turn off the green light indicator on my AirPort Express? It really annoys me.

    The Zed,
    You have two options and you probably won't like any of them.
    Using the Airport Utility, click on the AE then "Base Station", then "Options". That will bring up two options for you AE green light, either keep it green at all times or only light up when it is being used.
    The second option is put some tape over it.
    Hope this helps.

  • Green light flashing on my power cord

    I used my fully charged mac book today for most of the day with having it plugged in.
    when it notified me that I was running on the last 10 minutes of battery I went and got my power cable and plugged it in as normal to find that the green light flashed when I plugged in the power cable. When I pull out the power cable it stops flashing and turns to sloid green, not once have I seen it go amber like it should when it is charging.
    What does this mean?
    I can still turn my mac on but it isn't charging at all and the screen flickers in rhythm with the flashing green light.

    Welcome to Apple Discussions.
    From the stats you give you should be eligible for a free replacement battery under the following program: http://www.apple.com/support/macbook_macbookpro/batteryupdate/
    This provides warranty extension if your 1-yr warranty extension has expired. ( I always recommend paying for the Applecare extension for laptops.)
    To get this you might need to print this page and take it with you. The program is worldwide. Your dealer should cooperate as should Apple (NZ). Be polite but don't accept 'No' as an answer.
    Best of luck.

  • Dv4-1365dx Caps and scroll lights flash 4 times.

    When I turn on my computer, the hard drive starts but then stops. The lights on the touchbar (next to the power button) come on, but the screen does not. Then, the caps lock and scroll lights flash 4 times in sequence. My warranty expired last year, what do I need to do to fix my problem?

    If the hard reset suggested by Erico does not resolve the problem,
    I think it is a hardware issue with graphics if the leds are blinking 4 times. Refer the following weblink:

  • Desktop Computer dc5750 shuts down and red light flashes on front of computer and won't start at all

    I have a DC5750 HP Compaq Computer it is 6 years old, but I have 4GB Ram, Nvidia GS8400 Graphics Card, two one TB Hard Drives. While I tried to re-installed my operating systems it all of a sudden shut down not once but twice, I opened up the side of the computer and found that it was hotter then normal. I let it sit for a while thinking it maybe over heating after hooking it back up I turned it on again nothing happened except a beeping noise and red lights flashing on the front. Can this be fixed as money is an issue.
    Thanks

    Hello AlexCornejo,
    Thanks for using Apple Support Communities.
    The screen you're seeing on your iPhone indicates it is in recovery mode.  Now since the device is not appearing in iTunes on your PC, first follow the steps in this article:
    iOS: Device not recognized in iTunes for Windows
    http://support.apple.com/kb/TS1538
    After following those steps, you should be able to restore your iPhone.
    Take care,

  • My webcam won't stay on in skype - it flickers on and off and says it's not connected

    can't use my webcam for skype - it won't stay on. It goes on and off and says it's not connected. If I go to the webcam it is working. how do I resolve this?

    You say "If I go to the webcam it is working." Does that mean you don't have this issue in other programs? Also is it a USB webcam or is it attached to the laptop?

    What is indicated by the green light on the charger going off and on every second?

    Usually it is a charger or battery issue.
    Try a SMC reset:

  • No power and green light on my hp pavilion is flashing

    Hello,
    I'm trying to figure out if the power supply on my hp is bad or not. The green light on back of the tower is flashing and the computer won't turn on. I've tried all of the preliminary things and nothing works -- the green light keeps blinking until I disconnect the large plug to the motherboard, then the light stays on and doesn't blink. Once I have the power cord disconnected and the main plug to the motherboard disconnected as well, I then have tried replugging the power cord and then replugging the main plug to the motherboard (kind of trying to jump start it), the fan tries to come one (but only for a second, then goes back off, so it won't boot).
    Does anyone know if this means that the power supply is bad or if something else might be wrong? I'm wondering if the power supply would be bad when the computer is clearly trying to start, but not quite making it.
    This question was solved.

    My wife's computer has been having the same problem several times. One solution I found that worked before was to unplug the motherboard power cable and the PSU power cable from the back of the PC and then connect the power cable and connect the motherboard power cable while holding down the power button. Scary, to say the least, but it worked, until one day I accidentally flipped the wrong breaker and then spend two hours trying the same solution with no luck and Googling again. And here is what I found. This is the simplest yet crudest solution. It’s easy and non invasive and it doesn’t matter how tech savvy you are. Take a blow dryer and turn it on to blow air at the back of the power supply for a couple minutes. When you see the light turn green you’re all set. It's worked for me after it worked for a hundred others, maybe more. See the testimonials on this site: http://talk19.wordpress.com/2008/01/13/hp-m7088d-power-supply-led-blinks-green/. It’s a shame that nothing like this appears on any HP site. So don’t waste your money on a new MoBo or PSU. All you need is your wife’s hair drier.
