T400 without BACKLIGHT, no status lights on the inverter

Hello

Backlight of my t400 died there not too long ago... pinkish hue before he cut out completely is the death, give right outside?

Apparently it's not the whole story, I replaced the backlight without success then replaced the inverter and don't always show no results.

An external monitor will work fine and I can see an image on the screen with a flashlight shining on the screen.

I noticed another symptom though, also the backlight works is not the green status lights on the inverter also do not turn on. However, when I installed the new inverter first I remember lights works but the backlight doesn't work do not.

What do you think guys?

A connector/cable problem, a problem of motherboard (fuse?) or UPS (I have a feeling that new one I got is fried).

Thank you

  • T - 42-'below LCD' (power, etc) status lights dark EXCEPT the wireless light.

    I have strange problems with all the ' status lights of below-the-LCD-display (power, battery, Caps Shift etc) being dark EXCEPT the indicator left wireless that works very well. "  All indicators failed at the same time, not one by one.  It seems strange that only indicator of wireless adapter is functioning normally.

    Otherwise, it works normally - start button on the screen of the IBM BIOS to XP, etc.  This happens regardless of the fact on battery or AC power.

    It is a 15 "2379 - R9U which has been my main workhorse for years.

    I have-

    1 reinstall the motherboard toward cable Panel and inverter LCD on all ends.

    2 replace the inverter think there is a problem of logic (the power of the fluorescent backlight of LCD was going well on the original), and the same behavior occurred.

    3 tried reflashing the last BIOS 3.23 with the .exe file downloaded, but he refused because it was the same version not an upgrade.

    This could be a faulty cable across the LCD, signs a card dying mother, faulty RAM, etc. ?

    Y at - it no diagnosis to test this?

    When I had the same problem, a few years before, on my T23 the motherboard has been replaced, fortunately at the time it was still in warranty.

    The LEDs are sitting on the inverter. As you have already replaced, I guess it leaves that option to replace the cable to the rule, try it before you can certainly say that it is the motherboard, unless of course others have other ideas.

    Hello

    You must press the button on / off LED, which is part of the multimedia buttons of Toshiba. This button must be placed in the line where the other buttons such as play, pause, volume up and down are placed.

    So the light must be turned on. Then, you can set the backlight on the keyboard to Auto.
    Then the keyboard would hit any key.
    When you use FN + (keyboard sign (Z)), keyboard backlight turns off / Alternatively

    No, there is no way to turn off the lights.  At this point, HP did not have this option available.  I had a Phoenix at the beginning and I couldn't even turn them off inside the case.

  • SVF152C29M lights when the charger. The charging light also lights.

    I checked the charger, it gives about 21.5 V and I opened the laptop and it seems to have the tension on most of the components. Windows warned me that the battery has been a failure. Is it possible that this laptop won't turn on because of a failed battery and that it also doesn't turn because of the battery charge light? I tried to measure the battery voltage and the best I get is 0.5 V. It has even boosted to 1V, but quickly dropped to 0... So my main question would be, is it the battery or motherboard. The battery model is VGP-BP35A

    An update of the situation:
    New battery arrived today and it solved the problem. This laptop does NOT work without a battery, or the light on the laptop when it is connected to the charger without the battery inside!

  • Connection status: unknown. The dependency service or group was able to start.

    Greetings!  I have a year old Dell Inspiron.  Everything worked fine last night, but when I woke today I couldn't connect to the internet.  When I put the cursor on the network icon, it says "connection status: unknown."  The dependency service or group was able to start. "My Windows Firewall is also disabled and I can't activate it automatically or manually.  In addition, the Windows Diagnostic tool cannot be turned on, and whenever I try to activate the Diagnostic Policy Service it also can not be done. It says "error 5: access is denied" when I try to turn it on manually.

    My antivirus (Avira) software is fully up to date from last night.  I even took it into Best Buy and they did a diagnostic test to ensure that a virus is not the cause.  The guy there said it was a software problem.  I tried resetting TCP/IP (netsh winsock reset) without success.  I also tried sfc/scannow in safe mode and windows without success.  Are there other options?

    Thanks in advance.

  • 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.

  • No amber light in the button walk / stop during sleep, now no blue light when Windows is running.

    The first took place several weeks after a mysterious ailment judgment then "standby mode". Last night, "closing Windows" hung for 10 minutes until that I forced the closure in holding the power button. Now, Windows loads and runs - but without the blue light in the power button.

    I would like to know why, how to fix it and - especially - if it's dangerous. I count on my computer for all of my business account.

    Any help will be greatly appreciated.

    Now, Windows loads and runs - but without the blue light in the power button.

    -> If Windows runs as it should then light is only an indicator of power. You're probably dealing with a faulty LED. Nothing to worry about.

    I count on my computer for all of my business account.

    -> It would be a case of all stored inside the computer records and no external backup? A big accident waiting to happen? If Yes, then this would be an ideal opportunity to review your backup strategy. How your business would suffer if you lost a value one day of data? Value of a week? The lot?
