  • Fan error 90b message on start up

    Getting fan error 90B message upon startup.  Says computer will shutdown in 15 seconds, or hit enter to proceed to login.  I cleaned the vents with compressed air...the fan is running and air circulating, and even chatted with tech support and upgraded BIOS as suggested by them.  Still getting message, but computer seems to working fine.  ANY IDEAS???

  • Error 90B - Fan not working properly?

    Hello, this is my first time here so please excuse me if I posted this in the wrong section.
    First, general specs:
    HP Pavilion dv6 Notebook PC
    Windows 7 Home Premium 64-Bit
    BIOS:  InsydeH20 Version CCB.03.61.09F.21
    Processor:  AMD A6-3400M APU w/Radeon HD (4 cpus ~1.4GHz)
    6g RAM
    (If anything else is needed to help me ask, and I shall post it)
    Last week I received an error 90B for my laptop's cooling fan.  I was playing Guild Wars 2 and in the middle of playing my laptop shut down suddenly.  When I turned it back on it presented the error I'm asking about.  The thing is, the system wasn't overheating in the slightest and the fan was working just fine before it shut down.  I've tried many fixes proposed on HP's website and from a couple of friends:
    -Compressed air blown into the vents
    -System restore to a point where the fan worked
    -Hard reset
    -BIOS update
    None of those proposed fixes worked.  However, I did find something that fixed it...for about ten minutes.  I fiddled with the Catalyst Control Center and set my CPU power back to its default 1400 MHz, and I shut down my system.  After I restarted it I miraculously didn't get the 90b error!  You could imagine how happy I was.  I shut it down one more time to see if the error was truly fixed, but lo and behold it showed up again.
    The only change that could have caused the issue was me downloading a program called SpeedFan to monitor my system's temperature (I did NOT (I repeat, DID NOT) change any settings using the program - I purely used it to monitor the temperature.)
    I cannot afford to have a repairman replace or look at my laptop as of now, we have bills to pay and food to get, and I absolutely NEED this computer to function.  I have work to do, and classes to sign up for, and we have no public computers for miles.  Please help me!

    Not every fan error is a heat error. There is a sensor that detects a bearing that is wearing out or spinning that is out of round. You can sometimes limp it along for 6 months before the fan absolutely has to be replaced. When it does you will not be able to get past the error. 

  • Fan error on IBM thinkpad X60s notebook

           When I switch on IBM thinkpad X60s notebook. I can hear a sound from fan like it is try to move and then stop. After awhile an error "fan error" appear on the screen. I would like to know is it related to fan problem? If yes, Do I need to change a new fan? Actually, this notebook is out of warranty. So what will it cost for fan assembly and the labour charge? I live in Johor Bahru, Malaysia. I would like to know is there any service center in Johor Bahru? Thanks for reading and reply to my post.

    Apa kabar?
    Sounds like you will need another fan installed. If you unit is still under warranty, call your local tech support to assist. I'm not sure about your exact location in Malaysia, but I know that there are some locations in KL.

  • My pavillion g6 notebook fan is not working how do i fix it?

    My pavillion g6 notebook fan is not working how do i fix it?
    i found out  a few days ago when i was not hearing the sound my fan usually does because its really loud 
    and then 1 day i got the message. and is there a way to make it quiet?

    Hey FlowZ,
    Here is the Manual that shows you how to remove all the replaceable part in the notebook. Go to page 73 where it tells you the part #'s for the fans depending on what your processor is.
    Now, i wouldn't advise you to remove it yourself. 
    But these are the steps to remove the Fan. 
    1. Turn the system board right-side up, with the front toward you.
    2. Disconnect the fan cable from the system board (1).
    3. Remove the Phillips 3.0 x 2.0 screw (2) that secures the fan/heat sink assembly to the system
    board.
    4. Follow the sequence embossed on heat sink to loosen the six Phillips 10.0 x 2.0 captive screws
    (3) that secure the fan/heat sink assembly to the system board.
    If you want to replace the fan just go to Hp PartSurfer and search by your product #.
    Here is a Document that will help you with Reducing Heat inside the PC.

  • Fan Error. Overheats Assistance would be appreciated.

    Hello, my laptop has been playing up for quite a while now, over a month. The fan error constantly appears on my laptop and it always heats up when im running basic things such as web browsers and even word. I only recently discovered that there was a program called HP Coolsense which some people on forums claimed saved their laptop. I accessed the program and i didnt notice a real difference but it still gave me hope. The next day I turned on my laptop and HP coolsense had mysteriously dissappeared. The only thing i had done the previous day was a few hp driver updates. I have really begun to become depressed with thi error. I attempted to blow compressed air into the vents to no avail, After five days and 5 empty bottles of compressed air my situation has become dire. I  have upgraded BIOS like many of the pages requested. However I am hesitant to reset my laptop or send it back to HP as some have done? I have watched many videos on opening up the laptops to access the fans and heat sink however I find it horrible that the process is so delicate in these paticular laptops as i believe that i have to remove the keyboard and other parts of the laptop. 
    Any help would be greatly appreciated.
    Regards,mglcamo

    HP provides very good Service Manual documentation for notebook disassembly. One of the main things is to keep track of where the screws go. Other thn that it is pretty simple, just a little time consuming. My laptop was giving no error and just shutting down when the fan would just stop turning. I used a pin in the vent to get it started again but finally ended vup replacing the fan which solved the problem. There was some dust inside but not as much as I expected for a 6 year old notebook. Make sure you clean all that out, especially what may be on the heat sink. Follow the service manual and be careful and you shouldn't have a problem. I looked up my notebook and got the part number for the fan and searched the internet. I got my replacement fan from Amazon for $7.39 plus $4.80 for shipping. The old one was also making noise,maybe from the use of the pin, but purrs lke a kitten now.

  • Satellite L850-1V0 - Fan error popped up whilst I was playing a game

    I recently got an error that popped up whilst I was playing a game, it said that the cooling fan had a problem and that I should shut it down immediatly and send it for service.
    This is the first time I have had this, and I have a program called Speccy that tells me the temperature for my computer and all these other things, the temperature is at its normal level and I have never had anything saying to me I had a fan error before.
    For safety I changed the battery from Balanced to ECO which dropped the temperature a little bit, I put my hand on the battery and it isn't even all that hot, I can hear the fan and I can feel something blowing out of the air vents.

    Well, it looks like it was only false alarm.
    Usually the notebook would shut down automatically in case of high temperature. This is kind of internal overheating protection.
    Anyway I would recommend you to monitor the temperature level and to keep eye on the cooling fans.
    Furthermore check if new BIOS is available. If new BIOS has been released, try the update.

  • Fan Error on X201

    I bought my X201 (3249CTO) last october from lenovo's website. 2 weeks ago, my laptop became unable to boot up except showing "Fan Error" message. Before that, my laptop sometimes suddenly shut down(directly to dark screen) with no reason. 
    The Warranty is going to expire tonight. I still can not find the entry to report this error and ask for repair on this lenovo's official website. Most links I've seen are "check....", "check...", or "extend or upgrade"... and some software solutions. I can not find any tech support email. When I go to the "CONTACT" page, most contact info is about sale, business. After I click, click and click, I found that "800-xxxxxxx" tech support number. Following the instructions, I press 1, 1, 1... and hearing a lot of electric voice"please go to www.lenovo.com.....", I heard that their manual service was only available during 8a - 8p Mon - Fri. While I'm most on class during that time. Why don't they have an email for warranty service?
    How can I contact them to return my laptop back and get repaired?

    @LilHayah,
    You would need to call the tech support via the number 800-xxxxxx then they would advice you on how to get the laptop shipped back for service or if you have a onsite service.
    There are no emails for tech support.

  • System fan error on g62-352ca on startup. are there two fans ie a cpu fan and a system fan?

    I get a system fan error on power up?     Are there two fans in the G52-352CA?   Ie a general system fan and a CPU cooling fan or just the one CPU/heatsink fan?
    If it is the CPU/heatsink fan then there are 4 part numbers for different options.   Is there some way to tell from the model number or features as to which is needed.    I would prefer to have the part in hand before opening everything up.    Are there better fans to buy and if so how do I find them?       This unit was always running a little on the warm/hot side,

  • "Fan error" on Thinkpad X201s

    Hello,
    My X201s surprisingly overheated and soft-shut down. Upon rebooting the BIOS interrupted startup just to say "Fan Error" and shut down again. Has anyone seen this issue before? Up until now the fan has been working!
    I took the keyboard off, and as soon as I press the power button, I see the fan spin for a few seconds then stop - it does not start again and says fan error. I have blown all the dust out, and the fan turns very freely - is there anything else I should try before I send the laptop to be repaired (it is still in warranty but it is a bit of a bore!)?
    Thanks for any help,
    Edward
    Solved!

    Either the fan is running a little slow or the temperature sensor circuitry is sick. Send it in. It is a pain, but it is the best choice.

  • Fan Error on x220

    Hi everyone,
    I have a (now) 2 year old Thinkpad X220 with Intel i7 processor (CTO 4286) with no warranty (only got the 1 year limited warranty, as I assumed this was a premium laptop).
    Sadly enough a month ago the fan stopped working, and I get a "fan error" message on boot-up. This as, in effect, turned my +1200 dollar laopt quite useless.
    What I have tried to fix it so far is the following (in this order)
    1. Blown out dust from the fan area
    2. vacuum cleaned fan area
    3. Dissambled unit, vacuum cleaned fan unit
    4. Applied small bit of oil to fan unit mechanism
    5. Reapplied thermal paste to cooling unit
    6. REPLACED fan unit and thermal paste
    However, the message is still there and my laptop (which cost me an arm and a leg, as I was planning to use this laptop for 5 years - just like my x41 before it) .. is still dead.
    Does anyone else had this problem (especially those that did not have the warranty anymore), and does anyone else has any other suggestion? Would much appreciate it, as I need this laptop and cannot afford a new one..

    "fan error" does not mean "too hot"; it means "running too slow". You probably need need a new fan. (The only other things involved are the fan sensor and a fuse (both part of the motherboard). They are unlikely causes and expensive to fix.

  • Fan error on T42...

    FAN ERROR message on T42 (model 2373)
    is there a way to clean the fan?
    the problem is intermittent

    well you can try to clean the fan, just take off the keyboard. And then use a can of compressed air to blow out the dusts (but make sure you hold down the fan vane).
