Satellite R830 not working - flashing power light

Hello

My Satallite R830 lights.

The power symbol flashes orange 8 times then pauses and restarts. There are 6 quick flashes followed by a longer 7 flash then another quick. The symbol wireless is lit (orange) all the time.

If I unplug the laptop and remove the battery and hold the restart button for 30 seconds then without taking the battery in the charger stops flashing and the symbol of the power goes to green, until I try to turn it on, it has a fraction of a second where it looks like it is starting then stops and flashing orange again.

Same thing if I unplug the AC adapter and the battery and then tried the above, but with battery or ac charger.

I tried with another adapter (same output amp and volt).

Can anyone help?

Thank you very much

> 6 quick flashes followed a longer flash 7 and then another a quick

If the power supply microcontroller has detected an error lamp DC IN sends a blink code.
The short means 0 and a long time means 1.
I have your case, that means: 0000 0010

Because the error code starts with LSB (least significant bit) to read it from behind
-> 0100 0000 0000 0010-> 40 H (hex)
Now, you will need to know what means 40 H

After a few details that I found on the internet, the 40 H could be the fault of S3V output. (S3V voltage is more 3.47V)

However, such errors are mainly related to the problem of the motherboard (internal circuit problem) and from my point of view of the party only a few replacement may fix this error.

  • My C50-A-1DV Satellite will not work without power

    Hello

    I have a new Satellite C50 A 1 DV.
    It doesn't work unless it is plugged.

    Anyone know if that is correct?
    It seems odd.

    Also the far left in the front (AC IN) never turns on.
    Is it OK?

    I would be grateful if someone could put my mind at rest!

    Thank you

    > Anyone know if this is true?

    No, this isn't correct. If the main battery is fully charged, the laptop must run also without the power adapter connected.
    In case, the battery not charging properly, get in touch with certified maintainer Toshiba in order to check the battery and if necessary replace it with another, a new.

  • 18 XPS does not start, the power light will not stop flashing

    I was upgrade this computer to Windows 10, I did install one instead, but the children had spyware which even then showing upwards. I did a refresh, there no I did an installation and finally got in windows. Some updates installed and restarted.

    The computer was bricked since. The only thing that happens is the LED which indicates the power above, the button will not stop flashing white light. Connected or not connected, after having held down the power button for 5, 10 and 30 seconds, the led stops flashing for a while and then again. I tried several points of sale. No idea if it is a coincidental breakdown.

    I'll change that.  I went back in and re-removed the cable from the battery.  I also removed the CMOS battery cable this time... I was at least an error message on the screen and access to the BIOS!

    My laptop is running or when it does it turns off suddenly without any warning.
    The power light is on, but the battery doesn't seem to be loading.

    I can't think that it's the battery that is the cause because power should keep the laptop or allow it to boot? Any suggestions?

    It could just be a memory, but in the worst cases, your motherboard is the problem

  • Dell Studio 540MT does not start, green power light on, but the Start button / clear stop completely

    Looking for assistance

    Have a Dell Studio 540MT (purchased in 2009), worked great until 2 weeks ago.   After a temporary system failure would not start.    The power light itself is green fixed.   The power button on the front panel is completely released.

    I read a lot of messages and other information about a similar problem.   Therefore, I did following:

    1. unplug everything, press the power button / stop for 1 minute and retries.   without success

    2. replace the CMOS battery.  without success

    3A jumps the Green and black 20 supply connection wire pins to motherboard.  It started immediately food, fans and hard drive.   so I assumed that the PSU has been authorized.

    4 replace the motherboard with a new mobo.  Curiously, in a first time, there was no change, but after about 2 minutes, the power button was working and power system.   Everything worked so very well.   I had also completely cleaned all the dust in the chassis and radiator, fan and had applied the thermal paster as directed by Artic Silver.   I even turned off after hours of race and restarted system.  Restarted, he noted that it took a couple times by pressing the power button to make it work.   Then the 2nd day I shut down the system by a normal shutdown through Win 7 and let rest for about 10 hours.   When tried to start/turning the power on again, same problem as the original problem... at first, before light power button would show amber flashing when first pressed the power button / stop, then once I unplugged the power cord and let it sit for 1 hour, the light power button showed no light, completely and again no restarts.

    5. I ordered a new power button cord (new)... This could be the problem and replacement will fix?   Is this a known problem that power button can cause this kind of problem?

    6 or is a problem of power supply?   But you wonder why the green light of the PSU and works very well when jumping the Green and black wire on the connector 20 pin?     Before I go buy a new power supply to other suggestions?

    Is there a known issue with button / stop itself and/or PSU on Dell Studio 540 MTs?

    Yes, the front panel can cause failure to start in some models, although I don't specifically remember if the 540 has been affected by this problem. Please let me know if the replacement resolves the problem.

    ATX power supplies should work. Here are the standard components of the Dell desktop computers.

  • S70-B-118 - Minecraft satellite does not work

    Hello

    I have just just bought my son a laptop toshiba for his birthday as he wants to use it for playing minecraft, and when we load the program keeps crashing

    Sadley we are not pros pc if little help would be great the problem.
    This is what happens. The prices we have reloaded the program on the laptop re how never sound still has problems.

    # Java VM: Java hotspot 64-bit Server VM (25.25 - b02 mixed mode windows-amd64 compressed oops)
    # Problematic frame:
    # C [ig75icd64.dll + 0x6bb23]
    # Write core dump failed. Minidumps are not enabled by default on client versions of Windows

    I guess that is not the problem of the laptop but there must be a problem of configuration of the game.
    In many games different cases (probably Minecraft too) do not work because of graphic card driver compatibility issues.

    This can be corrected by upgrading the graphics card driver.

    The Satellite S70-B-118 laptop supports two graphic cards:
    An external GPU: AMD Radeon R9 M265X
    and an internal Intel Graphics HD 4600

    In the case of the classic game to access the graphics card Intel HD 4600, I recommend you to install the graphics driver Intel page from Intel that contain the OpenGL:
    https://Downloadcenter.Intel.com/Dow...7-8-8-1-64-bit

    You must choose the zip package: file name: win64_153619.zip
    After downloading, unzip the package and then go to Device Manager, choose graphics card Intel, set to date.
    Now you need to choose the "Advanced Installation" procedure This will allow you to point to the unzipped folder on the Intel driver and finally update the driver.
    The notebook can also restart after the update.

    Note: this issue seems to be a particular classic gambling problem. This is why it is advisable to search for more details and the support of workarounds on classic Web site

    I hope this helps to get it fixed

  • A5383 S55D satellite will not start without power

    Hello!

    I have the Toshiba Satellite S55D A5383 laptop and I have a problem with the battery, I think.
    Laptop does not start without power. What is happening since last week.
    In fact, since April 2015 battery does not last as it did when I bought (may 2014).
    I have'nt registered the product and I think I'm out of warranty.

    So, what can I do to fix this?

    You'll probably just get a new battery which is what I did. Try Amazon.

  • C850-A797 - Bluetooth driver satellite does not work after upgrade to win 10

    My laptop Satellite C850-A797 upgraded to windows 10 last week and Bluetooth driver not working since upgrade,

    I installed the battery Bluetooth for windows ver.9 but it also does not work.

    can someone help me with this please?

    C850 satellite is not listed as a book of 10 Windows compatible.
    This means that Win 10 drivers are not available for this unit.

    In any case, I recommend you to go to Device Manager and remove / remove Bluetooth all the partners of the devices and entries.
    In the view of mark tab also the option Show hidden devices in order to get the big picture complete.

    Now after reboot, win 10 must search for removed devices and drivers missing.

    I hope this could solve your problem of BT.

  • Re: My new C50 of Satellite does not work / blue screen

    Hello

    My mother just bought a new computer. We began to set it up (hopefully, this is the correct English word) for the first time. The operating system has stopped working after a few minutes.
    I explain (I'm not very good at this ^^).

    I turned it on, the computer asked a few things like what color, we would like to be, give a name to the computer. And then he Laura to be connected to the internet. I tried to do, but it did not work.
    So now, I'm just a big blue screen and nothing I can do. I can't go back to the first step, and I can't move forward because there is nothing else than this big blus screen.

    Can someone help or not the slightest idea what should I do?

    Thank you for your help

    PS: English is not my mother tongue, sorry for the errors of language.

    Hello

    Is there a button NEXT to proceed to the next step in the implementation?

    Press the power button and hold the button until the phone switch. It again, and I hope that you will be able to continue the installation of Windows.
    What I always do is to finish the configuration without WLAN settings. Later, when Windows is configured and fully charged, I put WIFI password and everything is OK.

  • Satellite M40X-189 wont start - Power lights but the white screen

    When you power on the laptop the power light lights up and the supply fan turns on but nothing on the screen.
    Then sometimes shuts down or blue light stays power away, and eventually turns off.

    So frustrating, have no money for the nine for daughter or to pay for costly repairs, praying there s an easy solution (but deeply towards the low no it will not be case).

    Any help will be really appreciated.

    Try reinstalling the memory (RAM). Or if you have recently installed more RAM, remove the additional module
