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.

  • Does it matter if the lightning cable is plugged in but not connected to an electrical outlet? Will this drain the ipad battery?

    Does it matter if the lightning cable is plugged in but not connected to an electrical outlet? Will this drain the ipad battery? We use an ipad cart at school, and some of the teachers will connect all the ipads up to the cart, but then neglect to power up the cart. The laptop with the cart has already had the battery wrecked because of this (within a two month period), and I am concerned the ipads may have an issue if this continues to happen. I need some reassurance before I make the other teachers paranoid!

    ok this one is kind in the gray area for me. I say if it is plugged in to a power up cart but not plugged in to a outlet, then all is is doing is not charing, and of course lossing a charge over time in standby, not really causing any issues. User guide and apple sites say it will drain the battery life.
    Important: The iPad battery may drain instead of charge if iPad is connected to a computer that’s turned off or is in sleep or standby mode, to a USB hub, or to the USB port on a keyboard.
    however “Battery life” means the time your iPad will run before it must be recharged.
    so I think it will be ok, as long as you charge it as usaul it should be fine.
    just use these links for and understanding for batteries and the ipad, of course the user guide.

  • My photoshop elements12 will not update says error and contact adobe but not open now for help.  windows vista

    my photoshop elements12 will not update says error and contact adobe but not open now for help.  windows vista

    I need the updates because I just purchased a Nikon D60 and my Photoshop does not read the .NEF files produced by the camera.
    Camera Raw plug-in | Supported cameras
    Camera Raw-compatible Adobe applications
    Do you really mean the Nikon D60 which shipped in 2008? Was it purchased secondhand?
    The Nikon D60 was first supported in Adobe Camera Raw 4.4.
    Photoshop CS4 ships with Camera Raw 5.0 so it can read D60 NEF files out of the box. No updates required.
    If you do mean the D60 then something else must be going on. e.g. are you using Nikon software to transfer files from camera to computer?

  • Why does my computer say that its plugged in but not charging yet the battery is not reducing

    it says plugged in, not charging, 99% (battery life)
    but the battery life is not reducing & hasnt for 2 days. it just stays like that.
    hp pavillion dv5-2132dx    laptop
    windows 7 64 bit
    i have had a few weird occurences and im not sure what caused it. abruptly my speakers would stop working & my battery life would start reducing. that happened i think 3 times over the course of several months. this last time which was the 3rd is when i changed electrical outlets thinking that maybe that was the problem. and the power & speakers immediately went back to normal. its only been a few days since i changed outlets & everything is working as it should be however as mentioned the battery icon on the taskbar says that its plugged in but not charging & it remains at 99% for the last 2 days.

    Hi,
    First of all, shut down the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for 30 seconds.
    Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here.  When the uninstall is complete, shut the notebook down, unplug the AC Adapter, re-insert the battery and then start the notebook on just the battery.  Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shut down the notebook again.  Now plug in the AC Adapter ( with the battery still inserted ) and start the notebook to see if this has helped the charging issue at all.

  • HP Pavilion dv7 plugged in but not charging.

    I have aj HP Pavilion dv7 that's almost 2 and half years old. For some reason my battery won't charge even though I have the charger plugged in. Right now the battery is completely dead but before it died I tried everything to fix it. I tried updating the BIOS but this website said my laptop was up to date. I tried a hard reset, I tried turning it on with the charger in and battery out. Usually the light next to the charger port is illuminated but now it doesn't come on. I hovered over the battery icon and didn't even say it was plugged in. It just showed how much battery was left. Could the battery not be receiving charge or is it my charger that doesn't work?

    Does the charger run the machine with the battery out? If so, the charger is good. 2.5 years is about normal battery life so the odds are strong you just need a replacement battery now.
    Yes, the charger works with the battery out. My question is however: I just  bought a replacement battery, my problem is that my  battery is plugged in but not charging. I bought a non OEM Battery FY1. Is there help for this? Thanks

  • Battery plugged in but not charging

    Hi @all,i need help, my laptop when it is switched on it plugged in but not charging. If i switch the laptop off it is loading normally! For me it looks like a safety for the battery, that if you have conected with charger that it is not always charging?Can you please help me out here?The type is a HP Envy TS 15 NotebookWIndows 8 installedthanks and regards

    Hi, I have an HP Envy 15 TS.  Same problem. As long as the laptop is turned off, the battery charges. As soon as I turn the laptop on, the battery stops charging. According to HP's website, when the adater is connected the led next to the connector should turn white if there's current flowing. If the battery is charging, the led should turn orange.  When the laptop if off and I connect the adapter, it's orange. When I turn the computer on, it turns white. In Windows, the battery icon says that it is connected, but not charging. The laptop is new, purchased about 3 months ago, and because of this issue it hasn't been used. I also get the "you can get a better experience with a better adapter" message. The adapter is the one provided with the laptop. I have talked to support on the phone. They disabled quick launch to get rid of the "better experience" message but they failed to identify root cause for the charging issue. Batter is ok according to tests. Adapter is also ok. Support said to take the laptop to a support center. Did that. They were baffled. Laptop came back the same after a little over a week, and the apologized for not being able to find the issue and didn't charge anything for the work. That is how baffled they were with the issue. The technician told me that after working with the Envy he noticed that another laptop, from a different vendor, had exactly the same issue. He also noticed that in the case of that laptop there were a few pending updates for the operating system. He said he applied those and things started to work as expected. He applied all the available updates for the HP laptop, including BIOS uprades and the problem persists. TIA, Marcelo

  • How can I get my ical events from my iMac to my iPhone? Anything I entered into ical on my iPhone will transfer to ical on iMac when plugged in, but not vice versa.

    How can I get my ical events from my iMac to my iPhone? Anything I entered into ical on my iPhone will transfer to ical on iMac when plugged in, but not vice versa. I think I have changed my iPhone (after looking at similar questions) to iCloud, but it's still not syncing.

    You need to sign into your iCloud account on your Mac, and check the Calendar option. System Preferences>iCloud, sign on your iCloud account, check the apps you want to sync with your device.

    I just brought my Mac book pro 15" 2.3 ghz on 12 september 2012 not even one week I've used it the battery cannot be charged.
    the upper corner right says it's plugged in but not charging.
    How do I solve this I'm going to London the next week! (23/09/2012)
    I need this replaced or repaired ASAP. Is tat possible? It hasn't being used for even a week and it's already cause such a trouble? Is this what Mac is?

    Hi Steve,
    I just got back from the apple service centre. I must say they treat us pretty bad and raising voices and stuffs.. If you wanna question or doubt on such service, I've recoded everything in my mobile and iPad. The company I brought from is TECHNOCRATS in 1Borneo Hypermall. The service centre headquarters is DIGITAL FORTRESS SDN. BHD. located in Damai Point.
    Here's what happened..
    I went in the service centre and disappointingly, no one entertain us (my boyfriend and I).. we stood there for a few minutes. :(
    Till we enquire for administration and problems. A girl said she doesn't know much. She gave me a number to her superior named Charles. She asked us to contact him. Then we asked "aren't you suppose to call your superior regarding to this matter?". "it's this the part of your profession to call Charles? Why is it my job to find him?"
    Soon the lady calls him and she passed the phone to my partner.
    Wow, there was raising voices and stuffs in the phone. So my partner asked him to come up to the office and discuss this matter since he was jst downstairs. For your information this is the second visit of the day, so we visited the second time after lunch hour which is 2:15pm
    Well it was dramatic, Charles with his raising voices and terrible attitude for a greeting. So he straight forward blamed us for not putting the mbp down to the registration. (FYI no one there bothers to serve us for the 1st and 2nd visit). For my concern, this mbp is not cheap. And how can I just put down my laptop and leave? Without any rational reasons.
    Long story short, I told him my problem and he said he will make a diagnosis and will return the answer to me tomorrow probably before noon.
    Here's what I'm upset about. I enquire about the genius bar. He kinda felt offended and told me tat only apple store has genius bar! Im just asking you don't néed to be so loud on this.. I'm still very new to Mac products and stuffs.
    Now that I have sent in my Mac book pro to diagnosis with the cables and everything. Hope to get the answers soon and hope it wasn't really bad since it was new.
    Now its pretty much scarred on my side about Mac's Brand. I just wanted a reasonable solving problem and yet I get negative feedbacks from the service centre. Is this how it should end? I'm still pretty upset right now.
    Any suggestions for me? Please?
    Worried,

  • HT204053 My kids now each have an itouch, should we all have different apple ids even if I am paying for all itunes and app store purchases? what about icloud? I would like to share itunes and app purchases, but not necessarily photos...help please!

    My kids now each have an itouch, should we all have different apple ids even if I am paying for all itunes and app store purchases? what about icloud? I would like to share itunes and app purchases, but not necessarily photos...help please!

    The recommended solution for most families is to share the same Apple ID for iTunes and App Store purchases, so you can share your purchases, but us different IDs for iMessage, FaceTime and iCloud.  With this arrangement, each person can automatically download purchases made on the shared ID (by turning this feature on in Settings>iTunes & App Stores), while keeping their FaceTime calls, text messages and iCloud data (including photo stream) separated.  There is no requirement that the ID you use for purchasing be the same as the ID you use for these other services.

    Add another e-mail account to your messages, so people could reach you on that e-mail from messages. As soon as you are online (if you have wifi only iPad) you are able to send and receive messages. i.e. your son can send you a messages from his iPhone addressing it to your (that additional) e-mail address.
