Pavilion a1620n won't start, the fans are not running. PS on the light and Sun. Start button does not illuminate

Pavilion a1620n won't start, the fans are not running. PS on the light and Sun. Start button does not illuminate. EU tested ps and I was told it was OK. Disconnected from the motherboard except course before directed ps button and the cpu fan has become much brighter, but that's all that happened. Any suggestions on what to check? Checked with VOM push and he seemed to agree. Replaced the MB with the new Board of Directors, that didn't work either. Don't know if it was any good, it was a store Bulletin Board.


All the indicators you mention leads to the PSU, not the Board of Directors.

  • Satellite P100-324: the Fans are still running

    Hi to you all,.

    Maybe you can answer me the question.
    Is it normal that my laptop fans are still running. I put the 'silent' settings in the bios and forced the laptop to run always on 1000 MHz, if I only use it for writing
    in Word or reading emails.

    It's really annoying. I don't know what to do.

    Thankz for your help in advance


    Hello Michael

    It is nothing unusual that cooling fan runs constantly on low speed. On modern laptops, there is a powerful hardware that needs to be cooled correctly. Especially many different processes are active in the background and CPU is standing under pressure. Not much when you use just the laptop for writing, but obviously enough to increase the temperature of the CPU.

    Try it please set the CPU and cooling to a minimum level method. Also check the Task Manager and end the process, you don't need. Maybe this will help!

  • HP Pavilion p6510t won't start, need help!

    Hello, we have your desktop HP Pavilion p6510t with the following specifications:

    HP Pavilion p6510t PC

    • Genuine Windows 7 Home Premium 64-bit
    • Intel (r) CPU Pentium (r) Dual-Core E5400 (2.7 GHz, 2 MB L2, 800 MHz FSB)
    • SDRAM DDR3 800 MHz 4 GB [2 DIMMS]

    • Microsoft Office Starter 2010
    • No additional security software

    • No speakers

    • Built-in Ethernet port, wireless
    • Audio Reader, 2 USB, 15-in-1 memory card
    • No TV Tuner
    • Integrated sound
    • HP USB keyboard and optical mouse

    We also bought this monitor to her (though I doubt it's important in this case):

    HP S1931a 18.5 "diagonal LCD screen

    The problem started about two months ago when the computer turns off without reason then that slowed down (before sleep should have started). After the computer restarts, he gave the beep codes that there was a problem with memory (1 short beep, 1 beep, long pause, repeat) long. After power back off and remove all devices and the power cable, the RAM has been removed (2 x 2 GB), checked for dust, bad seats, pins bent, etc...  The 2 RAM sticks have been resettled and the problem seems to be resolved.

    Fast forward two months (a bit more under warranty), the same problem occurs. This time, replace the RAM has not fixed the problem. Sometimes the computer should boot properly and then randomly cut regardless of what the processor was doing (idle or under load of 25% or more). In addition, beep codes would perhaps only half the time where it would not start. The output has been verified for feeding and another (proven) outlet has also been tried. No change. At this point, the computer won't be enough for any start screen at all, not even a blue screen.

    What he do to power on:

    • All powered fans (power supply, fan CPU cooler, case) and a spin at full speed.
    • Hard drive to wind up.
    • Green light on the power supply remains stable.
    • VA CD drive open and close normally.

    What is does not power upward:

    • No display at all.
    • No beep codes.
    • No blue light on the button walk / stop (top of case).
    • CPU does NOT get hot to the touch after 5 seconds to be under tension (with the fan and the heatsink removed and unplugged).
    • With two strips of RAM not removed, no beep of any kind.

    I also tried to use an old video card, I had to hang out, thinking that maybe the onboard graphics card were no longer works. The video card gets power as his fan runs, also at full speed. Still no display.

    I already bought a pair of replacement RAM sticks, exact same specifications and brand (Crucial), no difference. I tried all combinations of each stick into each slot with the original of the RAM in the first place, so I assumed it was sticks and replaced. Now that the RAM has been replaced and no beep codes, I suspect the motherboard or the CPU.

    I also tried to reset the BIOS by removing the battery for 10 + minutes and also move jumper to 2-3 1-2 during 10 seconds and replace (with power off).

    What I want to know is which component I need to replace to get this computer working before its tax season. I'd like to think it's the processor, because it remains cold to the touch after turning on. If this is the case, can someone confirm that this is a suitable replacement? (Intel Pentium E5700 Wolfdale 3.0 GHz LGA 775 65W Dual-Core processor desktop BX80571E5700

    If it's the motherboard (I hope not), it can be replaced without having to re - install windows? I can't find an exact replacement for the H - I41 - Μatx Foxconn (Eton). HP has one of these in stock that could be shipped out?

    I know that the computer is already out of warranty (barely) and can do the work myself, but need help to determine the problem I want to throw the money to do this work right.

    Thank you in advance for your help!


    Hello jkalbin, I think a bad mother rather than the processor card. Chess with the processors don't happen often at all. You should never feed a computer with radiator/fan all not attached to the processor. Just 5 seconds without the radiator/fan could easily burn a processor.

    The fact that the processor had no hot does not mean it does not work, if the motherboard does not send power to the processor.

    Motherboard failures are many times more often than the failures of processor. I had one processor to fail in more than 25 years of working with computers.

    Just some thoughts.

    My conclusion: HP BIOS/USB controller isn't working okey with WD My Book when you start the computer. If you wait about 3-4 minutes, to return to the boot. If you re-create the partition in Windows 7, you might be able to speed up the process. I have converted the MBR to GPT (Google more) and reformatted it NTFS. Reducing a starter and holds a GPT formatted, cannot be a boot disk. Now, there are about 1 min delay. If there is a switch to turn off USB Legacy support, that could help. There is not, thanks to the crappy BIOS HP. You can also seek support from Western Digital and discover interesting things.

    Then, finally, it'll pass the boot.

  • HP Pavilion dv7 won't enter the BIOS. Anyone (Esc, F9, F10, F1, F2 etc.) on the key

    I have windows 8 32-bit installed and keep start normally any key (Esc, F9, F10, F1, F2 etc) at the beginning, is pressed or hold... it will not stop the boot and won't let me in the BIOS. All it does if the keys are pressed, it emits beeps but boot then anyway.

    I want to boot from USB and install WIndows 8.1 64bits.

    Help, please.

    Thank you

    This could help you as it solved my problem yesterday. I disabled quick start (or quick start) in the settings menu of your laptop. I have turned on one day, not knowing that it prevents you from all the boot options. I'm at work and do not have access to a large part of the internet, but google "disable fast boot windows 8 ' or 'disable' quickboot. There are quite a few Web pages that walk through it.

    I am now able to access BIOS.
