E MACHINE T5026 KEEPS LOOSING POWER DUE TO OVERHEATING. ANY SUGGESTIONS
I'm not sure if your unit is a laptop or tower but if it's a tower, check to see if the cooling fan in the power supply itself is running. If not, fix it. If it is, UNPLUG the unit and open up the power supply itself. This fan will find every speck of dust in your house and deposit it in every nook and cranny of any tower power supply. I cannot stress enough to unplug the unit and DO NOT use any metal tools, picks or probes and KEEP YOUR FINGERS OUT of the unit. These are usually what's called a switching supply and develope several hundred volts early in the circuit and, like the television, they have high voltage capacitors that can retain a charge even when unplugged!!! If this is the case, if you have a mini vacuum, use it to clean it out. You can also "CAREFULLY" use the hose and flat tipped upholstery attachment of a regular vacuum cleaner being careful not to move or bump any parts out of position as their positions are in some cases critical to keep the supply from radiating RF noise back into your computer or out to other appliances around the house. If worse comes to worse use a small wood or plastic handled artist's paint brush, close your eyes and blow it out. While you are rooting around in there, you may want to look for any electrolytic capacitors that have bulging tops, discolored resistors, transistors, diodes or other semiconductors and their associated heat sinks if any or the area under these parts on the circuit board itself. Any of these parts can cause the problem you describe.
I suggest this ONLY if you feel comfortable around high voltages. If not, DO NOT try this!!! Open the supply and run it until it malfunctions. When it does, take a can of compressed air like you use to clean your keyboard. Attach the enclosed tube to the spray head and give a short spray to each semiconductor one-at-a-time. Spray a part, watch to see if your function is restored. Spray another, watch again. Continue this until your unit is working again and this will be the faulty part. We used to be able to buy small cans of R-12 freon for this purpose until they found it ruined the ozone layer.
If it is a laptop, make sure your supply is not laying on a carpet, bed, pillow or any other plush surface. Make sure you have it on a flat, hard surface to allow air flow around it.
