Check the a/c unit. make sure you dont have any leaks around your system. sometimes when you have a small leak it will take time to lose out of system. but you may need to charge your unit up again. Also your compressor may be out of service. check and make sure compressor is running

In AC mode the cooler fan doesn't turn on and after a little while the warm air starts to blow instead of cold air. Any ideas


Sounds like a bad or stuck reversing valve. Typically r.vs. are energized in cooling, verify 24 volts to valve, if yes , bad valve

Hi,

In Most cases this happens when using Nvidia graphics.
You need to open your laptop - call a technician for professional Job is you are not able to do so.
After removing the cooler which usually comes with a small fan (covers the main processor), remove the processor and you will see a chip that need a "HOT AIR STATION" this tool blows very high temperature of air on the surface.
well I used my wifes Hand Hair Dryer - also does the magic.

Why is my laptop overheating?


You can try a Targus Lap cooler to circulate the air a little better. The fan may be working but just not as efficiently as it used to. You probably have noticed that it works longer and better in cooler rooms as well. A lap cooler will help with the cooling issue.

Hello sir, hi, try to check if the side exhaust fan is blowing out reasonable amount of hot air, if not you side exhaust fan is dirty, it may need cleaning, If the exhaust fan has reasonable amount of hot air blowing out, then you may need to buy laptop cooler, inquire about it at your laptop dealer.

HOT AIR BLOWING INSIDE THE HOUSE


I know there are not that many sites--very few--that cover the informational guidance on the maintenance and technical difficulties of evaporative coolers, and so I feel compelled to share with you this very good, but rare, handyman site that does:

http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Coolers.htm

As you'll see, the link above has a section dedicated to evaporative coolers.

As to your specific problem of your cooler's blowing hot air, yes, the humidity is listed as one of six (6) possible causes of this cooler problem. To find out whether the other five causes are applicable to your situation, here is the direct link to the diagnostic article on hot-blowing coolers:

http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Home_Improvement_Zone_Cooling_Ventilation_Systems_Coolers_Cooler_Does_Not_Blow_Cool_Air.htm

You should be able to review this article, and, one by one, determine what causes listed therein are not affecting your cooler in order to ultimately end up with one remaining listed cause that is the likeliest cause of your cooler's failure to blow cool air into your house.

This should help.

Good luck!
