Having problems with your Acer Extensa 5420-5687 Notebook ?

I am having two problems with my acer extensa 5420...first is overheating, which was very occasional when I first got it so I ignored it and now it is getting worse. the fan is running but it gets very hot and will sometimes black out. the second problem just occurred, I when I put in a cd it tells me it is blank, but the cd works elsewhere... it used to work this is a new problem


Answers :

Have you tried cleaning the dust out of the computer? My Extensa 5420-5687 has aluminum heatsinks which are connected by a copper heatpipe. The heatpipe runs to the (viewed from the front) left-hand rear of the computer (where the cooling fan is). At the end of the heatpipe is a small radiator. This radiator gets clogged by dust easily and must be cleaned at least once a year.

It's easy enough to clean; use an anti-static wristband, a vacuum cleaner with hose (I prefer using a Shop-Vac) and crevice attachment, a clean (and dry) toothbrush, and canned air to finish it up. Use the anti-static wristband on the hand you'll be using to hold the vacuum hose and make sure it's properly attached within the laptop. With the toothbrush, scrub the dust off the radiator and vacuum it up simultaneously -- you don't want the dust going further into the computer. When you're satisfied that it's clean, use the canned air to spray from outside the laptop through the radiator (while vacuuming, of course).

After the radiator's clean, take the fan housing apart (four screws) and clean the fan with the toothbrush and vacuum. Take the crevice tool (if applicable) off the vacuum hose and **** the dust out of all of the cooling vents while spraying canned air through the fan opening in the direction of the vent you're vacuuming. Press the vacuum hose directly against the vent for the best results. Put the fan back together, reinstall it, and close up the case.

When that's finished, vacuum out the keyboard (using the toothbrush and vacuum as before). You'd be amazed at how much crud gets in there (and at what an effect it had on the performance of the computer). Good luck!

My Asus PG221 monitor suffers from frequent issues in which brightly coloured pixels randomly appear on the screen, then the screen will go black for a few seconds. Sometimes 'DVI - no signal' will appear, and usually the picture comes back. However, the issues do not cease. Seemingly the only way of temporarily stopping them is leaving the monitor overnight then switching it on again, after which I get about 30 minutes usage before the problems begin again. The problems occur particularly when
