White light issue

Greetings,
I have a compaq 615, the problem is that when i plug the power jack in, the white light turns on for a few seconds and then it turns off. The lap top does not react at all no lights at all.
I have tried the 30 seconds reset method still nothing.
Update: It is out of warranty so i disassemble it so i can clean the dust in the pipeline. Reassembled it and now it turns on but it shuts down directly after a few seconds with or without the battery attached.
Any idea of what it might be??????

Hello alexbedini,
Welcome to the HP Forums.
I see that you cannot get the Notebook to turn on. I will try to help you with this.
I have a couple of documents for you to start with.
Computer Does not Start (Windows 7, Vista, XP)
Battery Does not Power Notebook or Hold a Charge
I would like you to read over those documents and try the steps suggested between them. The issue, at this point could be a few things from bad power adapter, bad batter, a short to the motherboard ect. Try ruling out as much as possible.
Please let me know how that all goes. Thank you for posting on the HP Forums.
I worked on behalf of HP.

  • Weird keyboard lighting issue -only white background

    Hi Guys
    I am a bit stumped,  for some reason my keyboard only shows white light instead of colours. If i log off and on some times the colours do change (some times only). I have updated the BIOS and steel series engine, steel series does come up every now and then with "driver not avaliable.application will exit now". i installed the one from MSI and from Steel series website and still nothing. This only started after i closed the lid (sleep mode) and let the battery run flat.

  • I am unable to set my WD mybook world edition (white light) for time machine.

    I have new iMac running OS X Mavricks 10.9 and a WD mybook world edition (white light) connected via eithernet to router.
    I am unable to set up time machine using this drive. 
    I can see the MyBookWorld drive in Finder and read and write files with no problems.  I can also see the MyBookWorld_Backup drive but I am unable to connect.
    Time machine can see the drive but when I select, use drive, it trys to connect and gives me an error message: There was a problem connecting to the server "MyBookWorld-Backup"
    I have already updated the hardrive firmware.
    Any ideas?

    WD and their lack of support for Mavericks:
    A recent email from WD reads:
    Dear WD Registered Customer,
    UPDATE: November 1st, 2013
    As a valued WD customer we want to make you aware of new reports of Western Digital and other external HDD products experiencing data loss when updating to Apple's OS X Mavericks (10.9). WD is urgently investigating these reports and the possible connection to the WD Drive Manager, WD Raid Manager and WD SmartWare software applications. Until the issue is understood and the cause identified, WD strongly urges our customers to uninstall these software applications before updating to OS X Mavericks (10.9), or delay upgrading. If you have already upgraded to Mavericks, WD recommends that you remove these applications and restart your computer. If you have already upgraded to Mavericks and are experiencing difficulty in accessing your external hard drive, please do not save anything to the drive, disconnect the drive from your computer, and contact Western Digital Customer Service at http://support.wd.com/country/ for further assistance.
    The WD Drive Manager, WD Raid Manager, and WD SmartWare software applications are not new and have been available from WD for many years. However, solely as a precaution WD has removed these applications from our website as we investigate this issue.
    Sincerely,
    Western Digital
    Which is basically Western Digital informing you that their out-of-date utilities don’t support Mavericks.
    In any case those utilities are not the most effective. The moral of the story is: the first thing you should do after buying a WD drive is to format it as HFS Extended (Journaled) and not install ANY of their utilities but instead use reliable applications like CarbonCopyCloner or SuperDuper - or Time Machine.

  • My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

    My macbook air wont boot up. Just beeps every 5 seconds and a white light flashes on front of keyboard

    That normally indicates an issue with system memory. The startup sequence can't complete the boot due to a memory issue. Take it in for service.

  • White light, no display or startup

    So I'm deep into the trail of tears with my MBP 2.4 a1229. I very cleverly spilled some hot tea on my display which essentially killed it. 2/3 dead but everything else worked. I hooked it up to an external monitor and used it for a few days while waiting for replacement parts. No problems with the functionality of the computer at all. I ended up replacing the display and the keyboard. Upon reassembly there were a couple issues. The display worked and the keyboard worked but the computer wouldn't automatically sleep when you closed the cover. The screen would stay lit with it shut and just go to sleep after the designate time. I didn't think this was a huge issue and was just going to take it apart again once I got the time and see where i missed something. Well 4 days after the initial repair I put the computer to sleep before I went to bed and tried to wake it up in the morning. White light in the front is on but no one is home. I have powered it up and down a number of times. the drive spins up but there is nothing on the screen, no start up tone at all and no action other wise. I have tried an external monitor without success. I've reset PMU, changed seating and reseated RAM and tried with and without the battery. Researching i've found a number of issues that might fit like the logic board but the delay in the issue and the sleep problem make me wonder if it's not something simpler. Anyone think this might be some sort of hinge or sleep sensor issue? Any input would be greatly appreciated. Just as a note, I'm 4 hours from the nearest apple store so...

    The sleep sensor consists of a reed switch and a magnet. The magnet should be on the edge of the display--you can usually find it with a paperclip. I think we may have the same Mac, and on mine the magnet is on the right side of the display a little over halfway up. When you close the lid, the reed switch would be in the corresponding spot under the top case near the optical drive.
    My guess is that the reed switch could be malfunctioning or broken, especially since the computer wouldn't sleep when you closed the lid. Either that, or the magnet was missing or out of place. It's also possible its cable was damaged.
    You can also try the steps in this article and see if anything helps:

    It's even possible that your computer had developed the NVIDIA issue:

  • Just a SIMPLE query: No blinking/pausing white light when asleep?

    Hello all.
    Just got my new Intel iMac, very cool. I've set the mac to Display Sleep only and no HD sleep, when the screen goes black, there is no blinking white light at the lower right corner of the iMac, unlike my 1st gen G5 version.
    How would I know then for sure, that my iMac is asleep and not shut down?
    Thanks and cheers

    It would have been nice, if the black Apple for example would glow slightly, but no. There is no way of knowing it, other than pressing some key on keyboard. If it wakes up... Oops, it was sleeping. If it doesn't, then it is shut down (or otherwise unwilling to co-operate with you).
    I wonder, if this really is some environmental issue. Powering off your computer uses less electricity? If so, that is good, because climate change has struck again: Another christmas in a row without snow here in southern Finland...

  • Iphone 5s had white light leaks on lcd after unlocked with touch id

    My iphone 5s had white light leaks on lcd after unlocked with touch id. It's a bit confusing because if I unlock with passcode, there's no white light leaks. Does anyone have the same issue? What should I do?

    Title: Burst of White Light on iPhone 5S and iPhone 6
    Description:
    On unlocking the device with Touch ID a burst of white light is produced from the Top Left/Right corners of the screen.
    It happens when more than two folders are created i.e three/four folders each having some applications and the phone is locked while on the same screen.
    If no folder or maximum two folders are created then no such burst is produced when unlocking with Touch ID.
    Steps to reproduce:
    1. Configure Touch ID
    2. Use Black/Dark wallpaper on Home & Lock Screen.
    3. Create minimum four folders either on the home screen or the second having some applications in each.
    4. Being on Home Screen lock the phone.
    5. Unlock with Touch ID and a Burst of White Light will appear on Top Left/Right Corner.
    6. Now move/drag two of the folders to the other second page.
    7. Go back to Home Screen and lock the phone.
    8. Unlock with Touch ID and there is no Burst of White Light.
                        OR
    Repeat step 1 and 2 as listed above.
    1. Go to the second screen (after home screen) and create three or four folders with applications in it.
    2. Lock the iPhone while on the same screen.
    3. Unlock with Touch ID and there is a Burst of White Light.
    4. Now drag or remove the folders with only two left.
    5. Lock the iPhone while on the same screen.
    6. Unlock with Touch ID and there is no Burst of White Light.
    NOTE: If iPhone is LOCKED and UNLOCKED when on the screen with no folders NO WHITE BURST is there.
    Problem Since:
    Burst of White Light when apps added to a folder and unlocked with Touch ID. This is noticed since the update iOS 7.0.6 [11B651]
    Devices:
    The burst of light on iPhone 5s is easily recognized but on iPhone 6 its for a fraction of a second. Not checked on iPhone 6+.

  • Compaq Laptop CQ60-615DX Little white light beside the dc jack blinking repeatedly non-stop

    Compaq Laptop CQ60-615DX white light next to where you plug in the power cable keeps blinking. Never stops Blinking. Computer doesn't power on.
    The DC jack is loose, took the laptop apart, pressed down on the dc jack to hold it in place, and stuck the power cable back in. Tried to wiggle the cable around to see if the jack is bad. But it feels pretty solid, it's just the housing holding the dc jack in place that's broken.
    But I'm still getting the little white light beside the dc jack blinking repeatedly non-stop. No system power.
    Question is.
    1. Is the DC power jack bad and needs to be replaced or.
    2. There is a short in the motherboard and the motherboard needs to be replaced.
    I have check all over the internet for what the white light blinking means. I've found no answer.
    Could someone please tell me what is wrong with this computer?

    I already encouted this problem yesterday and I want to share this information on how I was able to fix this issue where in the dc jack blinking repeatedly and the laptop wont turn on.  This issue is resulted due to overheat so laptop automatically shutdown and results to some kind of hibernation.
    1. First you need to dissamble your laptop (compaq cq60). To clean the exhaust fan. I cleaned it because it was very dirty. I used my laptop for almost five years. If you dont know how to dissamble your laptop, you can check the tutorial from youtube. Just be very careful.
    2. After Removing all the parts you can use a brush to remove all the dust inside your laptop. After cleaning all the dirt inside the laptop you need to let the motherboard cool for 1 to 1.5 hrs. 
    3. When you put the dc jack dont put the battery. So once you plugged the DC jack you can see if the light beside the jack still blinking or steady.
    4. Once the light is steady., you can now power on your laptop. and a message will appear that your laptop overheated.
    5. You can use cooling fan to prevent from heating.
    6. Clean the parts inside your laptop every half year. to remove dust that cause the exhaust fan not to work properly.
    Now I was able to use my laptop again.
    Best Regards to All!

  • Ongoing White Balance issue

    In a video I just shot there is a slight shift in exposure in the image - just when my subject moves a couple times. It is shot with a white background and she is wearing black. I think this is a white balance issue. Which filters or fixes are best for this? I have tried a few filters and they mostly do it but you can still see the couple times my subject moves and the light/exposure changes. I realize that I need to film it better, but can it be fixed. Thanks for any insights.

    Search for "flicker fixer premiere pro".  I don't use any of them so you will have to see what works best for you.
    You can use the Fast Color corrector in PP to change exposure.  You will have to make key frames.  If you're not sure how to use key frames and how to use the Fast Color corrector it's time to open the manual.

  • Creative Zen X-fi (with lan) white screen issues

    ?Hello everyone, So I've been having my zen x-fi for a few months and it has been working excellently...until yesterday when it suddently (after what might have been a lightly hit, I had it in my front pocket and bumped in lightly into some object)...well suddently the screen went white but kind of still something black there (see photo below) <a rel="nofollow" target="_blank" href="http://img40.imageshack.us/img40/666/dscf2249redigerad.jpg"]http://img40.imageshack.us/img40/666/dscf2249redigerad.jpg[/url] I have been looking into troubleshooting about this particular issue, but what is suggested there under the white screen-issue is to reset and update firmware, something I did already first thing after it happened. The thing is that other than the screen being a quaking mess, it seems to otherwise be in working condition, because when I turn it on and push the play button music will still play as before. it's just the screen that is the problem. Any ideas? Best wishes, Babba

    Hello there, thank you for your welcome. That is sad info about my music player though, I liked it so much while it was still working. unfortunately im not within the warrant period so I will have to invest in a new one. thank you for your help though. I will look into which creative player is the best one within my price range

  • The white light

    I've had a mac for years, but I also had a Dell that was my workhorse and the mac did most of my boutique issues like keynote and itunes.
    Now a have a new MBpro that can also use the dark side of the force [ vista ]
    What I was wondering - is there a way the user can shut off the white light on the open button other than turning the whole thing to a cold off- it actually awakens me at night in the room, like a friendlier version of a HAL 9000....

    Hi Thomas, this isn't possible, best to put some tape over it.

  • White Light on Bionic

    When I use the USB cable (Ecomoto) that came in the box with my Bionic I get a solid White Light in the upper right hand corner of the phone.  I had used this cable in the past to sync my phone with the computer and had no issue, but all of a sudden it just gives me a "white light" on the phone.  I have tried it on different computers just to be on the safe side and have the same issue...Please help...I really need to be able to use this cable to transfer data and charge my phone when at work/school...
    Thanks

        Sounds like  you may have an issue with your device's cable farmmom! Have you been able to test it with a different cable, or is this the only one you have? If you're unsure of which cables will transfer data, you can always stop by a Verizon Wireless retail store with your laptop to test one out.  It's also a good idea to restart your device and retest.
    Keep us posted on your results!

  • Rephrased Question: No amber or white light on front functioning anymore

    I am an early purchaser of Apple TV. Until about a month ago there was a white light in the front of the Apple TV, except while sleeping. This is the same light that would flash amber to denote problems. That light no longer operates either white or amber. I called Apple and the tech person said that light on her Apple TV does not operate either. There is only a smaller light to the side which is functional on both hers and mine. I am wondering what happened to the larger white/amber light and if anyone else has experienced this same issue. All else with my Apple TV works great.
    Thanks.

    No idea what the issue is - I guess it's still under warranty if you're that worried.
    If it works then maybe you're happy without the light.
    You might try unplugging from the mains and letting it sit for an hour or so then repowering.

  • My g5 imac will not turn on and has a flashing white light

    Could somebody please advise me?
    I tried to install RAM in my imac g5.
    Unfortunately I purchased the wrong RAM so when I opened the bottom I took out the original RAM to compare the two and put the original (512mb) back in, closed the compartment and sealed the bottom with the two screws again.
    When I tried to turn the imac back on the screen was blank and the white light in the bottom right hand corner was repeatedly flashing.
    Help...

    I had the same issue.  Found another post that you need to push with surprising force with two thumbs.  I did so, felt a slight click; started it and we're golden.  Pulling the old RAM out though, I realized it has little tolerance for torque without jamming.  So save the force for when you are certain you are in straight.

  • Western Digital My Book (white light) not connecting...need advice

    Hi...I have been scouring forums for the past hours trying to trouble shoot this issue.
    At one point (it may have been with Leopard) I was able to back up all my pictures and music onto my WD MyBook. It showed up in Finder. In fact, when in Finder I GO>>CONNECT TO SERVER....My Book is listed as one of the recent servers. However, when I try to connect it cannot find it.
    I tried the Safari Bonjour...MyBook is not there either.
    I have reboot my computer.
    I have reboot the MyBook.
    I unplugged the MyBook and the router (Airport) for 30 seconds, then plugged it all back in reconnecting.
    I pressed the little reset button the MyBook.
    No connection. Both the top and bottom bright white lights are illuminated and not blinking or anything on the MyBook.
    Help....this was the 1TB external hard drive and I really don't want to just give up and spend another 200+ on a new external drive. Luckily my mac has behaved and I don't necessarily need my backup files...but I want to have a reliable backup in case something does happen. I am a photographer so backing up my many many files is necessary.
    Any suggestions? If there is no way to fix (which is what I gathered from some of the forums I already visited)...then what other system besides western digital can you recommend? Apple is super expensive....Iomega seems decent, and also LaCie...but then again, I thought Western Digital was good too. Help....

    Pondini will probably have my head, but I'll go ahead with my suggestion anyway:
    1. Because WD drives (enclosures) are not the most "trouble free", I'd seriously consider getting another external drive such as a LaCie or one from OWC (madsales.com).
    2. I personally have chosen not to use Time Machine; I don't like it because I can't boot with it and I don't feel it is very reliable either, so I'd suggest downloading either SuperDuper or CarbonCopyCloner (I use both). Install it in your Applications folder. Open Disk Utility and - either with your WD or the new drive attached - format the drive (click on the partition tab):
    Choose how many partitions you want  (one or ?) and name each one.
    Choose Mac OS Extended (Journaled) format.
    Under Options, choose GUID partition scheme (necessary to make it bootable).
    Click Apply.
    NOTE: this will erase all contents, so if you have anything on it you need, temporarily copy if elsewhere via drag 'n drop.
    After it's finished, open CCC or SuperDuper.
    Choose your internal as the source.
    Choose the external (partition) as the destination.
    Click on copy.
    When finished (my 80 GB takes about 40+ minutes), test it by going to Startup Pane in System Preferences, choose the external clone and click on Restart. If it does, all is well, and you can go back to restart with your internal. Once back on the internal, you can eject the external and unplug it/turn it off.
    You now have a fully bootable clone of your entire system.
    I update mine about once a week (that is all I need) - you can do it more or less often.
    Now, I maintain two bootable clones because hard drives can (and will) fail at any time. So, you could do a Time machine backup on the other one if you want.
