HP DV6 FAN REPLACEMEN​T AND LAPTOP REASSEMBLY - KEYBOARD NOT FUNCTIONIN​G PROPERLY

I called HP Store staff and was able to identify the correct model fan to replace the one in my DV6.  I got it and just did the replacement.  To those unitiated, its a chore, but it can be done.  Give yourself a few hours and peace and quiet.  As I discovered, the tricky part is putting everything back.  I must have gotten 2 things wrong.  
One, the machine thankfully boots to the Windows Start page, and my mouse works fine, the keyboard is now a problem.  The keys don't match the screen and I am effectively locked out at the password screen.  The key for ENTER is 4.  So, what do I do?  Re install the cable from the keyboard to the motherboard?  Please advise your best suggestions.
Two, when I put in the power cord, the little light to the side of the power adaptor input does not go on.  I suspect that the power cord assembly is adversely affected from the reassembly.  Any tips?
Thanks,
TK 

Reading around on these support page, I figured the cable from the keyboard was not properly installed.  Its a tricky item best done with a pair of tweeers, a good bit of light and very close inspection.  When everything lines up, close the ZIF hinge and voila!  The keyboard now works.  And I can boot and get past the passwords.  
However, my power is not recharging my battery.  That is worrisome and a new issue (from last post above).
Please help.  Only a couple hours juice.  Thanks.

  • Cpu fan 90B alarm and plugged in but not chragiung alarm

    hi,
    I have HP notebook product: b6u29pa#acj and model: g6-2101TX.
    I am getting following problem:
    A. while start up pc i found alarm 930B cpu fan failure and then after restarting window7 start.
    B. many time when i put laptop for changing it shown plugging but not charging and led near to charging port keep on biking white colour. that time charging not happen so if i removed charger and keep on using notebook my battery level is not getting down and suddenly at one point notebook power off. That means battery getting used but notebook not getting understand and giving me battery low alarm. Then i have to remove battery and insert it again. it will work for 2-3 days n then same problem repeat.
    ( pl note that note book battery is good and giving 2-3 hours backup when fully charge)
    Both my problem was chronic so i took photograph when problem came and then given laptop for repair at service centre as it was under warranty.
    Then next day i received call from service centre that my laptop ok pl come and collect. so i went to service centre when i checked found same problem so they took back and said motherboard is faulty.
     for CPU 930B fan alarm they only clean fan may be alarm will come in few days.
    after 8 days yesterday i received  call again from service centre that my laptop is ok.
    now my question is if my laptop is not ok then what to do? as my warranty was exp. on 23.08.2014 ( i need few days for trial ) may be after replacing motherboard any other problem appear. Will HP give few days for trials?
    or any government intervention is required ?

    Hello @yoursviru ,
    Welcome to the HP Forums!
    I understand you have issues with charging and a 90b fan error on startup.
    To address your question about a trial period after repair: Typically the repairs should include a 90 day service warranty or the remainder of your existing warranty whichever is greater. This depends if the repair was done by HP or an authorized HP provider. HP Phone Support can confirm this for you.
    If the repair was not done by HP or an HP service provider HP cannot guarantee the work of third party companies.
    The power not charging the notebook could be an issue with the battery, internal power connector cable, power adapter, or motherboard. All of which are hardware related.
    You can read about the fan error here and what to do to fix it: System Fan (90b) error message on startup.
    To sum everything up. I suggest you get in touch with HP Phone Support as soon as possible as they are the ones who can give you a straight answer regarding service and warranty questions. My answers are based on personal experiences, as the forums do not offer service and are available regardless of the warranty status.
    Hopefully Phone Support can give you the answers you're looking for.

  • Using External Monitor as display, and laptop for keyboard and track pad

    Hi,
    I have an aluminum Powerboook that is about two years old and I have it attached to a Samsung Syncmaster 203B external monitor. I have been looking for a set of instructions so that I can set the displays (I have been scouting around the preferences window and display options) to have the highest quality. At the present the words on my external monitor are a little fuzzy and I bet could be improved. Also, I've got the monitor and the computer set to be mirrored, but I really don't need the laptop window to be active. I'm just using it for it's keyboard and trackpad and it's sitting on my lap.
    Thanks so much,
    Rob Collins

    Turn off mirroring if you don't need it. Set each display to it's native resolution. Your Powerbook is likely 1280x854, your Samsung is 1400x1050. Use the DVI interface.
    Personally, I just dim my laptop when using the external display, although technically it's still active. Confuses the heck outta me sometimes when an app throws a window onto the laptop.

  • HT203167 I purchased several songs and the music will download to my home computer and laptop but will not sync into my ipod...can someone please help me with this issue

    My purchased songs aren't lost the computer is not giving the option to put the newly purchased music into the ipod.

    How do you do what? Plug the iPhone into a USB port directly on your computer, or disconnect other USB devices? To disconnect a USB device unplug it from the computer. If it is a disk drive eject it first using the Eject icon in the System Tray. To plug the iPhone into a USB port directly on the computer insert the USB end of the sync cable into a USB port on the computer.
    If you are using all of the ports on your computer get a hub and plug low power devices into the hub (e.g., keyboard, mouse). Or get a hub with its own power supply and plug your high power devices (disk drives, DVD drive) into it.

  • My macbook pro 15 inch freezes up. I forced a shutdown. After reboot, system restarted to factory settings, applications/softwares disappeared, apple dropdown menu disabled, dock and icons missing, keyboard not functioning

    Hi. I'm in need of great help as I do not understand how this could have happened.
    I had my firefox on, with multiple tabs and windows as I was doing intense research for a paper. My screen then freezes up, but my mouse could still work. Having experienced this before, I immediately pressed and hold the power button till my macbook pro shuts down.
    After which, I switched it back on. To my horror, everything was resetted to factory settings: my desktop background was replaced, the fonts on the clock display were different. But this wasn't so bad.
    After which, I realised that my dock went missing, together with the icons. I clicked the apple drop down menu, and my screen hanged momentarily, and in that moment everything on the screen disappeared (including the upper dock) for a few seconds and appear again. Meaning, i cant click the drop down.
    Similar thing happened with my spotlight. Using the hot keys command-space, the dropdown appeared on the top right, but when i started to type, the screen disappeared and appeared again like before.
    Finally i checked my applications folder, and it seems like all the applications are missing, like they have never been installed before! Their folders are there, but the icons and apllications themselves aren't. No applications/software installed- not even the utilities and system preference softwares that came with the macbook.
    Luckily though, all my documents are safe. I just cant open them because my iworks and adobe are all missing and "not installed". I cant even access the internet. I'm doing this via my iPhone.
    So basically i cant do anything because my apple drop down menu is unreachable, so is my spotlight, and my apps/softwares like system preference, utility are all missing. Is there a way i can troubleshoot this? Or make my macbook work again? I have already restarted and shutdown and switch it back on again near five times.
    I know my explanation is long, but do help me if you can. I'm really at a lost right now...

    Hi
    Thanks for the help. I did what you advised, but it still did not work.
    The repair disk was successful. Unfortunately when the system restarted to boot my startup disk, I faced the exact same problems as I did previously. I also did a hardware test, but no problems were found.
    Even tried powering off and on the macbook pro again but the same problems remained...
    I tried to back-up my files too but they refuse to copy/move into my hard disk drive folder.
    Nothing works.
    Do you have other ideas? Or suggestions?
    Thanks so far!

  • Magic mouse and aluminum wireless keyboard not working in windows 7

    Aluminum wireless keyboard (fully upgraded firmware as of 2/19/2010) not working, or magic mouse. Both from Apple Store, not amazon or ebay.
    No error shown for magic mouse, only "connecting to device" for 15 minutes now.
    With keyboard, at times it shows an error, but sometimes it lets me type a passkey. It doesn't recognize the passkey although it's saying it's paired, it doesn't work.
    Help?

    Getting Bluetooth set up initially in Bootcamp is a bit of a hit and miss affair in my experience, but persistence pays off, and connection is reliable. I gave up with the keyboard on my Mac Pro at one stage, tried again a few days later and it worked.
    How did you do it?
    Persistence and repetition, reading lots of threads and getting snippets from various sources, can't recall any silver bullets.
    Have you searched this forum, there are a LOT of posts on the subject.
    Links please? I can't find any.
    If you type "bluetooth" in the search box while at the top level of the Bootcamp section you will get six pages of hits. Here are just a few, not necessarily the best or a complete list or in any particular order, but they contain relevant info.
    I can't remember the detail now but one of the key steps for me was launching the bluetooth "service" mentioned in some of these links. Initially option wasn't appearing at all. Also mine (and others) seems to need a single click after boot to be activated. If you try and move it before a click it won't respond so you might think it wasn't working.
    BTW I am assuming you have successfully installed the Boot Camp 3.1 drivers?

  • I have a MacBook Pro 15" 2.53GHz Mid2009.. updated to Lion which is now 10.7.3 build 11D50b... when I close lid and connect to Cinema Display, display will not activate... disconnect display, open lid laptop display will not activate... used to work fine.

    I have a MacBook Pro 15" 2.53GHz Mid2009.. updated to Lion which is now 10.7.3 build 11D50b... when I close lid and connect to Cinema Display, display will not activate when keyboard/mouse used... disconnect display, open lid and laptop display will not activate... only way out is hold power button.  Worked fine before Lion update.   Any Advice?

    Thanks very much Coander15... I've printed the doc you pointed me towards and I'll run through it.. hoping it helps!
    Before I installed Lion I simply hit any key on the keyboard or clicked the mouse...
    The keyboard is USB (usually connected to monitor which is connected to laptop... have tried direct connect to laptop as well with no luck) and mouse is USB wireless to one of those tiny plug in's... have tried direct connect USb mouse as well with no luck.
    I could plug the closed/sleeping laptop into the monitor and unplug from the monitor without incident all day/night... always worked fine. 
    Had heard something about this happening w/ Lion but went ahead anyway. 
    Oh well...
    Hoping your pointer helps... will let you know how it turns out.  Thanks very much for responding!!!

  • [HELP] HP Pavilion DV6-6b50sa fan - abnormal whirring and grinding noises even after replacemen​t

    Product:     HP Pavilion DV6-6b50sa
    Operating system:    Windows 7 64bit
    BIOS version:   F.1 C  (current)   01-2013
    My laptop fan started making a very loud grinding and whirring noise constantly (very loud, easily heard in other rooms from the laptop) and after cleaning out with compressed air with no improvement I decided to get the fan replaced as it was clearly worn out in some way. (This laptop fan has always been loud, but never making this sort of grinding sound).
    Replacement fan was ordered directly from HP and installed. However, while the noise is much quieter, the fan is still making a constant sort of whirring/very low grinding noise which gets louder and changes pitch whenever the fan kicks up to a higher speed.  While the laptop is now at least useable, this noise is still annoying after being on for a long time and I did not expect it to still have the same problem after fully replacing the fan.
    Since then I have looked online for solutions and similar problems, having since flashed the BIOS to the latest version, checked both the hard drive and memory in the BIOS (both proved fine)  and tried switching between having the fan mode set to always on or not always on in the BIOS and messing around with HP coolsense. None of these have helped remove this constant whirring sound.
    Now this laptop fan has always been loud. That I am ok with, I know the sound of a loud, yet working fan drawing air, but this is not the same sound. The fan is still drawing air sufficiently and keeping the system temperature down to an acceptable level, but this constant whirring noise is annoying when having to work on the laptop. 
    [In Summary]
    -HP Pavilion DV6-6b50sa  Laptop fan had loud whirring/grinding noise
    -Fan was replaced
    -Noise reduced and grinding somewhat gone, but whirring and some grinding remains even with the new fan from HP
    Any help would be great, I have tried to include as much information regarding the problem as I can but if there is anything else needed dont hesitate to ask and I can try to provide such information as required.
    Michal.

    Also, when the fan is running at higher speeds the whirring/grinding noise is quieter and less noticable than when it is running at very low speeds... When running at very very high speeds (while playing games)  the fan sounds almost the same as my old one when it was still working, and at high speeds its more a whirring humm... Then at lower speeds it goes back to a more low whirring/grinding.
    Not sure if this helps but its just something I've noticed...  Any help with this problem?
