Dead motherboard My presario F500EA went dead after my niece left it operating on the bed for a day. I suspect it overheated due to blocked vents. External power supply is ok. HDD is ok. I suspect motherboard is shorted. Please help me troubleshoot the motherboard. I know how to use multimeters but I dont know where to start. I dont have a schematic diagram of my motherboard. please give me tips on how to tackle this problem. Thanks so much.

Bad news - an overheated F500 is a really expensive paperweight. All you can really do is try and source a new motherboard and hope the CPU and RAM didn't go the way the board did...

My compaq 610 wont start up. went i connect de charger the powerbutton lights goes on en off.


When the power button blinks do you hear the laptop fans run on full speed? If that happens its because your laptop is overheating and is trying to cool down. It will not turn on until it cools down to protect from damage due to heat.

Use your laptop on a hard surface and dont block its vents with anything. If you want to use it on bed keep it on a laptop cooler or a thick book to allow ventilation.

If laptop doesnt turn on at all, the motherboard might be damaged. Take it to repair shop and check whats wrong.

Oven on convection for 45 minutes sort of thud then went dead no lights nothing, fuse is ok came back to it 3hrs later and is working again?


That is usually an overheating problem. It may be due to blocked air flow, a slow convection fan, or a failing convection thermostat / TCO.

My Kenmore Elite electric stove top will turn on fine, but it will randomly cut off. Then none of the burners will heat up, but lights are on like all is fine. If I turn off the power for 5 minutes it...


If it goes dead for a while during or after cooking then comes back on, the magnetron is probably overheating and causing the magnetron thermostat to open.

Then when it cools, it closes the circuit and allows power through again.

An overheating magnetron can be :
  • operating oven without cover(s) in place
  • wrong magnetron installed in oven
  • an old or otherwise failing magnetron
  • cracked magnetron magnet
  • improper power line voltage (US homes should be 110-125VAC)
  • foods low in moisture (popcorn & bacon, e.g. - add 1/2 cup of water in rear oven)
  • failed or inoperable cooling fan or hood vent exhaust fan
  • deteriorating foam weatherstripping seals in air ducts or on outside cover
  • blocked air vents (dust, animal nest debris, insufficient free air space behind & around oven, etc.)
  • clogged or greasy charcoal filter or grease filter
  • blocked duct in hood vent exhaust
I suspect a failure or the fan, clogged filter or bad magnetron.

I appreciate your thoughtful rating of my answer.

Battery dead, key stuck in ignition.


I have had the same problem with my daughter's car. She inadvertnetly left the key in the on position and the battery went dead. Apparently an electrical current is neded to withdraw the key. I put a battery charger on the car for several hours and everything worked fine after that.

Over heating of laptop


Causes of Laptop Overheating Physical Causes of Laptop Overheating
For a properly designed laptop, the most common cause of overheating is blocked air vents. When dust blocks the fans and air vents designed to cool your laptop, overheating results. (In some cases, blocked vents and poor design are related, as some designs are excessively prone to becoming clogged with dust).
Software Causes of Laptop Overheating
In other cases, laptops overheat because the software designed to protect the laptop – specifically by controlling the operation of cooling fans – does not work properly. In some cases, this is due to problems in the computer’s BIOS, and can be cured by upgrading to the most recent BIOS. In other cases, upgrading or changing the computer’s operating system can cause this software to not function.
If, for example, you have upgraded from Windows ME to Windows XP, the system software designed to operate the fans may no longer work properly. (What’s worse, the laptop manufacturer may refuse to provide support in this instance, on the grounds that you changed the operating system and so are no longer operating the system as it was designed to operate.) In other cases, replacing Windows with Linux has led to this problem if the proper Linux utilities to control laptop cooling were not installed.
Design Causes of Laptop Overheating
In a distressing number of cases, laptop overheating results from poor design by the notebook manufacturers. Some manufacturers cram desktop CPUs into laptop configurations, and do not adequately provide for releasing the heat that these desktop CPUs create. Others simply have failed to provide ventilation and cooling systems appropriate for today’s CPU and video chips, which hold many more transistors than in the past and so generate more heat.
Several class actions have been filed against laptop manufacturers due to overheating laptops, including Toshiba and Dell. Previous class actions have led to settlements under which compensation was awarded to owners of overheating laptops who ran up repair bills trying to get the problem fixed. More class actions related to overheating laptop and notebook computers are reportedly under consideration.check here for more information http://www.fonerbooks.com/lap_fan.htm
