    Acorp 6VIA81P no post

    Hello I have an old Motherboard

    Type: Acorp 6VIA81P Ver. 1.6

    It is works...and slowly died... freezing 1-2 times...and after that not windows starting...now totally not booting
    PCI post card 7 segment --,-- (1 times appear 06,05 but never more)
    Leds: IRDY, Frame, Reset not flash

    So looks like it is hardware fault..
    I checked some voltage, but looks like good at FETs
    Capacitors ok, not damaged (but not checked the values)

    SD ram 256MB tested in other board ok
    Pentium2 400 slot1 tested ok

    CPU hot
    Memory (board upside hot, AGP side cold)
    Nortbridge slowly warm
    Southbridge cold or very slow warm
    South FAN connector RPM sensing voltage is 0 (other FAN conn RPM sensing 5V) Q14 (2Ay) changed, because it was shorted burnt.

    So i request help what should be check.

    There's something that's decaying to the point where it goes dead... I have a 6VIA81P as well (not sure what revision it is at the moment, have to check) on which the same issue happens - no POST most of the times, constant restart cycle that prevents it from POST-ing, and keyboard won't work at all.
    Main rig:
    Gigabyte B75M-D3H
    Core i5-3470 3.60GHz
    Gigabyte Geforce GTX650 1GB GDDR5
    16GB DDR3-1600
    Samsung SH-224AB DVD-RW
    FSP Bluestorm II 500W (recapped)
    120GB ADATA + 2x Seagate Barracuda ES.2 ST31000340NS 1TB
    Delux MG760 case

      Whirlpool PACF212HP W portable air conditioner, upper fan only turns slowly.
      by spleenharvester
      I just acquired this portable aircon, history unknown. Its behaviour is quite strange:
      • When turned on and placed into cooling mode, the upper fan (cold air out) just spins slowly. The compressor and lower fan do not run.
      • If the device is then placed into heating mode and then back into cooling mode, the lower fan and compressor kick in and start cooling, but the upper fan still only spins slowly.
      • If the device is placed into fan-only mode, the upper fan does not respond to low/medium/high speed toggles - just keeps running slowly.
      • Display and buttons all behave normally aside from the

      Samsung un55ks800df - Display slowly degrades
      by p2computing
      Hello everyone,
      I have a Samsung UN55KS800DF

      When I turn the TV on the picture initially looks great

      After 10 seconds or so, the bottom of the screen starts to show issues and it slowly creeps upward

      Eventually the entire display is ghosting and distorted. If I power the TV off for a few minutes and power it back on, the cycle repeats with a good display that slowly degrades.

      I have attached an image of the display after about 3 minutes of being powered on

      Thanks in advance for all you do for us!...

      Lenovo Thinkpad 11e showing "Thermal sensing error" upon powering on.
      by SageHappy
      Hello guys,
      I hope you are all good. One day my Lenovo thinkpad 11e laptop just started displaying "Thermal sensing error" after I switched it on. At first I thought it was an issue to do with a defective thermal sensor in my fan. I replaced the old fan with another used fan but, the problem still persists. From where I bought the fan, they said the fan was working just fine so, my question is how can I rectify this problem. Thank you in advance.
