Question about HP Computers & Internet

(1) How do I turn off the computer fan from surging?

The surging is sporaic but once it starts it continues for 10+ minutes or more. Not sure what causes it to start or stop.

Other concern is that the computer appears to be constantgly running. How do I figure out what is running and limit these actions?

As far as the fan issue goes, especially if it's a laptop, blow out the fan exhaust area. Use compressed air to blow out the ventilation area in the opposite direction that air flows through it normally. You'll be amazed how much dust comes out. You can try one of those crappy over-priced ridiculously low pressure canned air deals but to really get it clean, find someone with an air compressor. A mechanic friend or someone in construction that uses an air nailer maybe? If it's a desktop, try blowing out the processor heat sink preferably with the fan removed. Be careful, start at lower pressure and slowly work your way up. Also, if you take the fan off of the heat sink, be careful not to knock the heat sink off of the processor or you will need to clean both surfaces (heat sink and processor), reapply a thin layer of heat sink grease, and reinstall the heat sink and fan assembly. I'll leave the second half of you question open incase both issues are one-in-the-same.

Replace the fan! The bearings are starting to dry out and that's when it will surge.

The other concern is a little more difficult from your explanation. Try this, open the task manager byt pressing ctrl+alt+del. When the window pops up, left click on Task Manager. Click on the Processes tab at the top of the window. Now click twice on the CPU column to sort the processes so that the highest number is at the top. That will show you which processes are using the most of the CPU time.

Hope this helps.

Freezer motor not restarting after it switches off.


Hello Rostakes;

My name is Peter. I am a retired field service refrigeration technician.

When you unplug your unit, then plug it back in you are giving the motor a surge charge with more volts than necessary to run the motor.
A bad evaporator motor will hum. The clicking sound that you hear is the motor fan blade striking something.

You need to check for 2 possible causes:

1.) The back cover in your freezer, that is in front of the evaporator motor and fan is very thin sheet metal and will easily flex. Inspect to ensure that you are not over packing your freezer and pushing against the back cover.

2.) It is common for the evaporator motor fan blade to have interference from icing. Inspect the back cover in front of the evaporator fan for frost and ice. Your freezer goes through a defrost cycle where the unit shuts approximately every 8-10 hours, the defrost heater turns on for about 20 minutes, the unit restarts. This is where they get the term; "Frost Free". If you have frost or ice on the back wall your defrost heater and Bi-Metl need to be replaced.

Due to the limited size of response by the site I can not walk you through the repair procedure for these parts. If necessary submit this repair procedure request to this web site.

After 10 minutes car engine start a/c goes off


Possibilities:
A: If the compressor turns off but the circulation fan continues:
  1. Insufficient refrigerant charge;
  2. Refrigerant overcharge, causing evaporator coil freeze-over;
  3. Defective compressor clutch;
  4. Clogged screen in orifice tube;
  5. Front condenser coil is clogged with dead bugs, dirt, foliage, or other material.
B: If the entire system turns off, including the circulation fan:
  1. Defective system breaker;
  2. Defective system relay;
  3. Defective climate control module (at dashboard);
  4. Fan motor overheating due to clogged air intake or other obstruction;
  5. Fan motor overheating due to debris in air handler box, such as leaves or other plant debris.

The fan continues to run. How long and will it automatically shut off?


The fan you refer to should be the fan in the oven cavity. It removes hot air from the oven cavity and expels the air out the front of the oven. Once the oven is turned off the fan will continue to operate until the oven cavity has cooled sufficiently. It may run for 10 to 15 minutes and will turn off by itself.

Computer won't turn on won't do anything , i had it connected and someone at my house was using electric drills and the fuse tripped and everything was shut down including my computer and since then it...


Try unplugging the computer completely from the wall for 15 minutes. Plug it back in, and see if it will power on.

If it doesn't it's most likely a blown power supply, when the breaker tripped, everything on the circuit basically fed back into everything plugged in. This is something most computer power supplies do NOT like.
The good news is, a power supply is generally pretty cheap, you can get new power supplies atarting around 20 bucks, although decent quality ones are closer to 50 bucks. Bad news is, there is about a 1 in 20 chance the power supply took other parts with it.
Once you do get it running, or get another computer, make sure to get a surge protector strip and plug everything connected to the computer into the surge protector. A 15 dollar surge protector can save you 150 dollars in parts and labor. (or more)

Freezer fan surges up and down


Don't worry, that is a variable speed DC fan motor. Fan speed is regulated by the mother board as needed.

Radiator Fan continuously running with engine off, discharging battery


It is not the fault: for long time Renault has that concept, that is to prevent engine oveheating when coolant circulation is suddenly stopped.

Radiator fan can continue to work up to 10 minutes after engine is off. You should worry about it only if it wouldn't stop even after 10 minutes.

Frigidaire Tumble Action Washer - lights flash, beeps, does nothing else...


If you have had a lightning storm or power surge it may have fried the electronics panel. That is what happened to mine. Once it is fixed you should put a surge suppressor on it that is rated for major appliances.
