If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.
  1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
  3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
  4. if still there no sign of life then send it to nearest service centre

My 17.5 briggs engine sounds like a helicopter what could be causing this?


Are you sure you got the plug tight and that the compression washer is good? A poor seal at the plug will cause a noise like that. Perhaps there is a piece of foreign material preventing a good seal. I would use a rubber hose on a vacuum cleaner and something like a dental pick to make sure the plug has a clean seat.
Good luck.

AEG Competence B3101-4m oven not working on fan setting. Fan operates but no heat. Also intermittent problem on full grill setting. Any ideas?


ISOLATE MAINS POWER BEFORE OPENING ANY PANEL
Several possibilites come to mind.
first Has this AEG two fans if yes , it has a top and back fan, the element on the back fan sounds like its either a bad connection or blown needs further investigation, the intermittent grill possibly a thermistat, of poor contact on a connection again. Rear and top panel access, you may have to remove the top fan.
Hope this has been helpful

If a PC suddenly fails to boot properly, you should perform a hard reset as the first action. Performing the hard reset will correct many problems. If the computer still does not start properly, select your symptom from the list below to guide you to the recommended corrective actions.
  1. Disconnect all peripheral devices and remove all USB devices and SD media cards. You want to test the computer not the accessories!
  2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds to drain all residual power and restore default startup settings.
  3. Reconnect the AC power adapter (but do not insert the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a fan or other moving parts turning.
  4. If the computer does not start, the LED lights do not glow, and the display is black, you can perform one or more of the following actions to resolve the no power issue.
    • Verify the computer is receiving power from the AC adapter . Verify that the AC adapter is not damaged and is connected correctly to a working wall outlet plug. Verify AC power is connected to the system board by examining the AC adapter, wiring, and pin connection for damage. The keyboard LEDs will glow when AC power is connected to the system board. Damaged components, like the AC adapter or the pin in the power connector, may require an HP-certified repair.
    • Use a different AC power adapter . If you have access to a different AC adapter or power pack that is designed for the computer, connect it to the notebook and try to start the computer. If you own or have access to more than one notebook, verify that you are using the adapter which belongs to the notebook. CAUTION: Using a power adapter that does not meet the power requirements or has the wrong type of connector may damage the computer. On newer notebook models, connecting the wrong adapter to the notebook may cause the power LED lights to blink but not power the computer.
    • Remove the battery and boot on AC power only . A discharged or defective battery may prevent the AC adapter from supplying enough power to start the computer. To verify that power from the AC adapter is available for PC; remove the battery, connect AC power adapter, and press power button. If available, try using a different AC adapter, that is rated for the PC, and repeat this test.
    • Remove the AC adapter and boot on battery power only . A defective AC adapter may not charge the battery and prevent the computer from booting on battery power only. To verify battery power available for the PC; connect AC power adapter, allow battery to charge for 30 minutes or more, disconnect the power adapter and press power button. If available, try using a fully charged battery, of the same type, from another computer and repeat this test.
      • If LEDS do not glow and the fan or hard drive do not spin, battery may need to be replaced.
      • If tests of both the battery and the AC adapter fail, there may be a problem with system board requiring service by HP.
      • If LEDs glow and PC boots, the AC adapter may need to be replaced.
      • If LEDs glow, but PC does not boot go to LEDs glow, fan is heard, but display is black or blank section.

Black screen &my laptop fan is runnig


Good day.

Black out monitor can be cause by number of reasons and errors. If you are feeling that the laptop's fan is working, then the power supply adapter and the battery is good. You may also try to use only the adapter by removing the battery or the other way around. This will isolate problems with the source of power.

Second, at the back of your laptop, you can see a removable panel cover (using an ordinary screw driver). Inside that panel is the memory. Try to eject/remove the memory module by exerting a light force on the knob at each end of the memory socket. Remove the memory module and try to clean the contact points using a pencil eraser. Corrosion and dirt may result in a poor contact with the socket. Re-seat the memory module and power on test.

If you still have a black out screen, the sad part is, the remaining culprits are the LCD monitor, the LCD hinge/contact points, the on-board video card and the motherboard/CPU. These parts are not user-serviceable and you need the help of a service man to disassemble and check the parts.

Good luck.

Hello, Matt.

Sounds like a conflict with your VGA card driver.

From Safe Mode, go to Add/Remove programs and remove anything related to graphics. Go to Device Manager and remove/uninstall any listings for Graphics Adapter.

When you restart, install the drivers from the CD. If the drivers need to be "executed" as a program, cancel out of the driver install and run the drivers program when you get into Windows.

Hope this helps.

We have a belling format oven - when we turn the top oven on it is making a sound like a helicopter


The noise is probably cominbg from the externally mounted cooling fan. to access it, you will have to remove the side panel and rear cover, and top cover if it is bullt in.
If it is free standing, you should be able to get to it by removing the top cover/hob.
Hope this helps.

My compaq presario c765tu laptop suddenly turned off while i was working with that.then when i tried to turn on, only the power light comes, fan moves and dvd drive opens but the screen remains off.nothing...


If the problem is with the RAM or Hard drive then atleast you will get the access to the BIOS and this is not related to the hard drive or RAM as there is no display on the notebook.
If the Quick launch buttons are glowing then perform the following:
1. Remove the notebook battery and disconnect the AC adapter. 2. Press and hold the power button for a minute. 3. Reconnect the battery and AC adapter then try to turn on the notebook.
If the display still doesn't appear then, connect the notebook to external monitor and check the display on it. If there is any display on external monitor then the issue is with the LCD screen. If there is no display on external monitor then the notebook needs to be diagnosed by a technician at the service center.
