Power button light has faded

ive got a hp pavilion dv5-1123TX which i bought about 6 months back..
its been working great..but since few days back..the power button's light has stopped working..perhaps it;s because of overheating or something.
sometimes it lits up on its own but most of the time i have to push the speaker area on the left just below the power button that it comes back to life..!
second issue which might sound even mroe trivial that the above one..is that some dirt particles have made its way into the diaplsy screen...it looks like just a speck on the screen but is very irritating nevertheless...!
any kind suggestion as to what to make of the above two problems especially the first one?..can they be fixed under guarantee as the notebook is still under warranty?..what say anyone?
regards,
shahzeb

Hi, if your laptop is still under warranty...Contact Customer care. Remove the hard drive before sending the unit in.
regards,

  • TS1587 My friend has a G4 that will NOT turn on at all.  The monitor power button will light up, but monitor won't turn on; the the computer power button lights up when pressed but won't stay on and nothing else happens.  He said it USED to at least turn

    Anyway, not sure if my question was sent, so here it goes:  My friend's G4 won't power on....the power button lights up briefly when pressed, but nothing happens....and, cannot even get the montior to power on...does the same thing.   He said it used to at least turn on, but now it's doing this.   Help!!??  What should we do??

    If you are able to use a multi-meter, you can test to see if the power supply is culprit. Use the Power Mac G4: Power Supply Voltage Test  (Sawtooth G4) document to aide you in the proceedure.
    If not the Sawtooth, Power Mac G4 (Gigabit Ethernet): Power Supply Voltage Test.
    If a Quicksilver, use the pinout of the QS PSU connector here:
    http://www.xlr8yourmac.com/tips/MDDps_mods/MDD_PSMods.html#update
    and a testing description here:
    http://www.jcsenterprises.com/Japamacs_Page/Blog/D275729F-09DA-4FBB-96B3-BEEEB2C 04619.html
    The test description is for a MDD, but the basics are the same.
    If a MDD,follow my instructions in the linked articl above.
    One should also try a PMU reset:
    http://support.apple.com/kb/ht1939
    One should also  replace the 1/2 AA PRAM battery.
    Also, check that the 20, 22, 24 pin connector is properly fitted to the motherboard, and that the wires are properly inserted in the connector. There is also a 10 wire ribbon, which goes from the motherboard to the power button board. Make sure that the ribbon is firmly connected at both ends, and that there is no apparent damage to the ribbon.
    If the power supply tests good in a MDD, the power switch board could be suspect.

  • Power button lights and fades

    I had to power everything down in order for some electrical work to be carried out in my flat.
    I did everything in the usual order but when I started up again my Liebert PowerSure gave a red warning light and the power button on the computer lit and faded when I pressed it
    I took the Liebert out of the loop and the G4 started up no prob and ran fine.
    Next day I plugged the Liebert in (no comp plugged into it) to test it and it seemed OK so I put it back but the situ was the same so I decided to remove it and leave it out for now but this time the G4 power button lit and faded even without the Liebert.
    I am thinking I need to reset PMU but just wanted to check if anyone agrees or not
    If so can anyone add a link to instructions, I had an easy to follow page from here last time I had to reset (after a power cut, which is why I got the Liebert in the first place)
    Also, any recommended implements to use for the reset? – I think I used a pencil last time.

    Instructions here. You may also need a new internal memory battery. See Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial

  • Shutdown doesn't shuts off the laptop in Windows 10 (64 bit)- FAN, Power button Light still on

    Hello. I have HP pavilion p045tx. Recently I upgraded to windows 10 update (64bit). When I shut down my laptop, the screen turns off but the power button light, fan etc still keeps on running. Previously I was running windows 8.1 home edition. I didn't face any sort of problem like this. Please give me solution what to do.

  • My Pavilion a6417c The 'power button' light never illuminates. The fans all run at full.

    My Pavilion a6417c the 'power button' light never illuminates.  The fans all run at full. The only way to turn it off, is to unplug the Power Cable from the PSU.  The system does not boot.  If the PC is unplug for more than a week, it will boot.  But after 5 minutes it will turn off.

  • X300 switch off power button light

    Hi all,
    is it possible to switch off the light on Power Button? Its so shining and its really uncomfortable.
    Thanks
    Jan

    Try holding both the power button and center button pressed at the same time for 15 - 20 seconds until the HP logo appears.  Now release the buttons.
    When it finishes restarting, things should be back to normal.

  • HT1320 Ipod 4th gen was accidentally disconnected from laptop during update process. Now permanent screen pic is of power cord w/ an arrow pointing up to itunes. Holding the ctr & power buttons together has no effect for reset.

    Ipod touch 4th gen was accidentally disconnected from laptop during update process. Now permanent screen pic is of the power cord w/ an arrow pointing up to itunes symbol. Holding the ctr & power buttons together for 6-10 sec causes apple pic to briefly appear and power cord/itunes pic reappears. Powering off and on has same effect. Attempting to reset.

    It sounds like the iPod touch is in Recovery Mode, Try to restore it from iTunes again.

  • Power button lights up  for a few seconds but does not power up

    Hello
    my computer froze up so i shut it down via the power button but now it does not power on when pressing the power button the button lights up but as soon I let go the light goes out and nothing happens not noise form the computer
    anybody can help.

    Hi, racb -
    Try resetting the PMU - Article #HT1939 - Resetting CUDA/PMU
    Also, it may be time to replace the internal battery. Those batteries have an expected life of about 4 to 5 years; leaving the machine disconnected from live power regularly or for an extended period can reduce that time a lot. You can get a replacement at places like RadioShack for about US$18, cheaper on-line.

  • DPG4 does not post -- but the power button lights up

    I'm totally lost at this point... My old PowerMac no longer powers on. I managed to somehow get it to boot when I had this problem once before, but this time I'm getting nowhere. When I press the power button, the button itself still lights up -- but that's as far as it gets; as soon as I take my thumb off of the button, it goes dark, and the system doesn't even try to boot. The steps I've taken so far to troubleshoot this are: removed all third party components, (including a 512MB DIMM, a USB2 PCI card, and a 54g wireless PCI card, as well as several USB devices) removed the power cord and backup battery and pressed the PMU reset button. Does anyone have any other suggestions?
    Fortunately, this is no longer my primary system -- a white 24" Intel-based iMac takes that title now -- but it would be awfully nice to be able to install one of my Leopard licenses (from the family pack) on the old G4 to use it as my Time Machine server.

    Thanks for the suggestions so far.
    Additional information: I just successfully booted the machine, through a series of (what I would call) almost random configuration adjustments. Here's what I did... I opened the box, yanked the backup battery and pressed the reset button again, and tried to power it on. I then noticed that the optical drive was connected to the ata33 interface. Thinking that this is a bit odd, I swapped it to the ata66 interface. (My two internal harddrives are both connected to the separate ata100 interface... is this a truly bizarre set of interfaces, or is it just me?) I then pressed the power button -- and the machine fans started blowing, and then stopped. Suddenly very interested, I promptly disconnected the power cable from the optical drive, and then tried again -- no dice. I pressed the power button a few times just to see what would happen, and I observed the fans on the rear of the power supply and one case fan were spinning up for just a bare moment about every few times I pressed the button. I then disconnected the main power interface cable from the motherboard, and did the whole pmu reset/battery out/pmu reset/battery back in series, and then replaced the power interface and pressed the power button. Voila! It powered up, so I promptly logged into the site and started typing.
    Now, here's my thoughts: I would assume that the fact that it is presently booted up and running (albeit without the optical drive) rules out a failure of the front interface; do either of you concur? Also: I have not yet taken my multi-meter to the power supply, but my first instinct is to think that the power supply is just on the edge of my current wattage requirements, and disconnecting the power from the optical drive is what allowed me to boot. Correspondingly, I would speculate that this could be caused by either 1) my add-ons have exceeded the 400 watt output of the power supply, or 2) the power supply is indeed starting to fail.
    So... since the machine is running at the moment, are there any diagnostic programs I could run against the power supply to find out if it's operating at design specifications? I'd expect this would be more accurate and more safe then me poking around with a multi-meter -- and it would be less expensive then a trip to a Mac repair shop, though that is certainly the next step if the power supply is dying.
    Thanks again for your advice!

  • HT5957 I have downloaded the ios 7 for my ipad and now my screen is locked and shows a plug pointing towards an itunes symbol.  Does anyone have an way out of this frustrating problem?  Holding down the home and power buttons together has not worked.

    I have downloaded ios 7.2 update for my ipad and now my screen is locked and shows a picture of a plug and the itunes symbol.  Does anyone have advice to fix this frustrating problem?  I have seen help online for iphones, but none for ipads.  The screen will not budge.  I have tried holding down the power and home buttons at the same time, to no avail.  Please, can some of you smart people help me?

  • How can I get the light for the power button to go back on?

    I would like to get the power button light to work properly again. I have a p6813W desktop running Windows 7, 64 bit OS.
    The first time the machine went into sleep mode and was awoken the power button light went out and has not yet to come back on even after many shutdowns and restarts. I can't easity tell if my computer is on or off. How can I get the light to work properly again?
    Thanks.

    Mac's don't have UI scale options like Windows has.
    Either you can drop the screen resolution in Displays a wee bit and make things appear distorted, or do what I do and use the Universal Access and set a control key, then use a mouse wheel/scroll to zoom in and out where the mouse is pointed.

  • Is the Power Button suppose to light up?

    Hi, I remember Macbook Pro's power button would light up with white light when it is on.
    My Macbook Air doesn't seem to light up the power button. Is it suppose to be like this?

    jamesjm88 wrote:
    Thanks for you answer! However I still think that it would have been a nice touch if the Power button lit up in white or green. Don't you guys think so as well?
    No, I don't think it's necessary to have a power button light up. If you're already using your computer and it's on, there's no need to additional indicators to tell you it's on. It's already on! The screen is alive etc.

  • Power button orange light

    i just discovered that the power light is constantly orange. But it used to be blue before.
    Any body knows what is causing this? Would be great with a quick answer The computer is an GE70 2PC Apache

    The power button light is also an indicator of which graphics in use.
    Like JakeSully mentioned, if you have program which is running by using nvidia graphics, then the power button light will light orange.
    First, make sure you don't have any programs running by using the nvidia graphics.
    If there is no programs running by using nvidia graphics but still lighting orange, try to completely uninstall the nvidia graphics driver and re-install the latest nvidia driver from MSI website and see if the problem still remains.
