Difficulty in the light on the AC adapter and the power light power on after connect you to the laptop

HP Pavilion dv3t notebook. Each time get adapter connect to the laptop, it takes at least 10 minutes to get the AC adapter and power indicator light on. Sometimes it does not light on all day.  It always happens any with the battery or not.

If I start the laptop with the light on the AC adapter and the power light, no matter how I move the power cord, it maintains support, works very well.

But if I start the laptop without the light on the AC adapter and the power led on even with the, i.e. start with the battery as power, no matter how I move the power cord, the led on the AC adapter and the light, i.e. no charge. He stops until the battery drain.

I believe that the AC adapter is good. But I have no idea why he has trouble in the light on the AC adapter and the power light on after to connect to the laptop.

Dv6 had a somewhat similar problem that was treated with a BIOS upgrade. I watched the latest BIOS for your laptop and there is nothing about a problem of load, however. If it works very well and also a long time that you turn it on with the AC plugged in but only has a problem with loading when you connect the adapter Windows runs, I'm tempted to say that it is a software problem as a problem with Windows power management. Maybe if you remove the hard drive, power supply, switch it on with battery only, then plug the adapter when you run in a pre-Windows environment, we can see if the same problem occurs. If it was my cell phone, I would also like to do the update BIOS level, just to see if maybe it would affect something. I could also try to run it from a Linux Live disc any and see if the same problem occurs in another operating system. Last resort I would begin focusing on the issues of possible material, as a module of taking bad AC, which is an other replaceable part that requires no welding.

  • dv5 1002nr difficulty for the black screen and 2 flashing lights

    Hello!

    So I have this laptop (dv5 1002nr) and of course just after the warranty goes out did the laptop. This original computer was one of my friends who took to Best Buy Geek Squad and they told him to fix this laptop it would cost $400 if not more.

    So to make a long story short, she got a new computer and I helped get parameter and everything and then I asked for this laptop (I have set now free) did not work if I could have. He was a useless piece of junk so she agreed.

    After about an hour of resistance tests, transistors, etc., I can verify that all energy through the computer is as it should. I spent maybe 30 minutes on Google without success, and finally I decided to try everything. I started with the new ram without success. I tried all the silly little "trouble shooting tips" HP has for this laptop.  I'm running a little more than 2 hours working on this seemingly useless task when I finally managed to make it work.

    I did about 3 - 5 times now and it works every time.

    First I remove all the ram and then turn it on. (of course it doesn't)

    Turn the power off.

    Then remove the processor and turn it on. (attention)

    Disable.

    Put the processer back in and turn it on. (still not working)

    Disable.

    Put the ram back in and turn on.

    That's what I did and it works every time for me.

    Since I was only 17 and a little short on money I can't go just around portable computers purchase like these with this problem and test this further.

    If anyone has this problem please try this and let me know.

    Oh and HP. thank you very much your 'support' really helped me... at the expense of my portfolio.

    Oh and one thing...

    I did the 'live chat' and they said that my laptop having is not a display might be due to my hard drive or the motherboard.

    1. the hard drive would not effect my monitor does not. Or on a hard disk of the computer AFTER.

    2. except when he said to the motherboard he also lies the processor he was wrong, once again.

    3. it is a faulty laptop and I know other people have had this problem I hope, they read this insead of wasting their time with "HP support".

  • Satellite L - water damage and the laptop does not light

    Hello

    I don't know if this is the right forum for this, but I was just wondering if someone could give me some advice. My brother spilled some water on my laptop 3 days ago (argh!). He immediately turned off and won't start up again. I stamped it towards the top as long as I could, removed the battery and positioned in a V shape to try to help dry. It is still not started. When I plug in the adapter, the screen remains blank, but there is a very low humming noise and the lights flash:

    The power light flashes green very clearly
    Battery green LED flashes weakly
    The hard drive LED blinks green VERY weakly

    I'm really hoping that the laptop is not dead and I'll at least be able to recover my hard drive, but it seems unlikely. I'd appreciate really any advice that anyone can give me in regard to what could be wrong or how I can fix this problem.

    Thank you for taking the time to read this.

    Hello!

    I agree with Luke and the best way is to contact you an ASP. They can check the laptop and tell exactly which parts must be Exchange or not.
    On the Toshiba site, you can search an ASP:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported downloads & => find an authorized service provider

    If the HARD drive is not defective, you can backup your data to another PC or laptop as Luke suggested.

  • Satellite A210 - 1 4 - failed to start the laptop computer just orange light

    OK, so this is what happened:

    While my friend was working on his laptop computer that she had his charger plugged but it did not load. I discovered that the lead from the Charger AC/DC had frayed and should resolidering. After that the laptop was working fine, I looked inside the laptop to check the AC plug connector before I fixed the cable.

    I noticed that the WiFi card was broke, so I changed it to a WiFi card in my other laptop used. After back the laptop together and put the battery in, the lights on the front flash blue only and the power light stays orange as if the laptop is in stand-by mode. I can hear the hard drive turns and the CPU heats more CD-ROM drive works, but I can't start that the laptop just sits there with the Orange.

    I tried out the CMOS battery, I took out the main battery and just used the AC/DC adapter, but the same thing happens.

    ANY IDEAS?

    Hello!

    I'm not sure, but what happens if you remove the WiFi card you created in? The new card is may be defective or not compatible with the laptop.
    You can start without WiFi card?

    To me, it looks like a hardware problem and your laptop should be checked by a technician of the laptop. Maybe the motherboard needs to be replaced or something else

  • HP 2004tx g6: laptop won't turn on with AC adapter and the battery

    Here's the thing.
    (1) the laptop doesn't work without battery when it is connected directly to the power adapter.
    (2) light, which would indicate that the laptop is connected to the power adapter is not on the power adapter is plugged in.
    (3) the battery charge light is also not on, which would indicate the battery is charging.

    The battery does not load... Laptop is running on battery backup mode, but not on the AC adapter connector. I tried to connect the battery to an another compatible hp laptop (my laptop and the other test device supports same battery models). It has been very well supported on this laptop. And when he spent in my laptop, laptop was working well, but it does not load in my laptop. But the AC adapter / CC is fine too. So what is the problem? And what I can do to get it sorted?
    My laptop is not guaranteed more. But I replaced battery 4 months back, if this is not a flaw with the battery or the AC adapter.
    The adapter is very good, tested with another laptop.
    The battery is also new and works fine
    Kind regards

  • Time Capsule A1355 no light, no sound? worked this morning now after connecting it, first go-ahead for colid quickly followed by the longest fixed Orange, which turns off and then nothing? He's dead now?

    Time Capsule A1355 no light, no sound? worked this morning now after connecting it, first green light solid, quickly followed by amber is more solid, which turns off and then nothing? I'm not in the airport or if directly connected to the Macbook air utility. It is running the latest firmware, updated 7 days ago and everything was fine until now. Tried both a soft and a hard reset factory but still nothing, but the same brief glow only after restarting each time before going dark again? Any ideas if it can be fixed or if it's as I read elsewhere dead now?

    Thank you

    Any ideas if it can be fixed or if it's as I read elsewhere dead now?

    He died... the fact that the main witness turns off is unusual in this model.

    It is common to the next... A1409 (gen4)

    What happens in the Gen3 is normally a few deaths on the Board... or a bunch of capacitors is low...

    See s/apple-time-capsule-repair/new-issue-with-a1355-gen-3-tc https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem

    If yours is a very fine introduces Gen3 just before Gen 4, it is possible that the same fix on the Gen 4 could work.

    s/Apple-time-capsule-repair/GEN4-a1409-issues https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem

    I found early Gen4 may fail as Gen3 but must admit that I am yet to see the Gen3 with welding problems.

    I doubt repair is worth it. The Gen3 is now about 6 years... give or take... This is way beyond the standard lifetime of a TC.

    If you want to play, I'm happy to help you... but I would not spend money on it.

    Hello

    Try disabling the startup of Windows 10 hybrid - you can do the following.

    Open settings and select System.  Select food and sleep, and then click additional power settings - in the next window, click on "Choose what the power button" in the left pane.

    In the next window, click on "Change settings that are currently unavailable" (close), then Remove the check mark from the box against 'Turn on a quick start (recommended) '.  Click on the button Save the settings, and then close windows open and stop the laptop by right clicking on the icon in Start Menu, select (Admin) command prompt and click 'Yes' to the uac prompt.

    Type (or copy and paste) the following command (including spaces) and click Enter.

    Shutdown /s /t 0

    Start the laptop and let Windows take over completely for a few minutes before checking if it is now shut down properly in the Start Menu.

    If this has fixed the problem, it may be useful by turning the quick start back on - sometimes simply remove and re-create the file will solve the problem.
