| 3 | __Diagnostic strategies:__ | ||
| 4 | |||
| 5 | Three of the PC models we have worked with so far have had various ways to diagnose errors encountered during their Power On Self-Test, or POST. | ||
| 6 | |||
| 7 | * HP Compaq - Red LED that flashes 1-5 times with an accompanying beeping tone, errors diagnosed [[here>>url:https://support.hp.com/us-en/document/c02222922||rel="__blank" title="HP Compaq error codes"]]. | ||
| 8 | * Dell Dimension - 4 LEDs on the back with A B C D labels that either light up green, amber, or not at all; error codes listed [[here>>url:https://www.manualslib.com/manual/227494/Dell-Dimension-2400-Series.html?page=35||rel="__blank"]] | ||
| 9 | * Dell OptiPlex - 4 LED numbers visible near audio input/output jacks; error codes listed [[here>>url:http://www.dell.com/support/article/us/en/19/SLN284978/a-reference-guide-to-the-dell-optiplex-diagnostic-indicators?lang=EN#2005_to_2009||rel="__blank" title="Dell OptiPlex error codes"]] | ||
| 10 | |||
| 11 | __Hard Drives__: | ||
| 12 | |||
| 13 | * The "clicking of death" - Hard drive problem where the hard drive makes a distinct clicking or scraping noise telling that the hard drive is most likely damaged beyond repair. [[https:~~/~~/acsdata.com/hard-drive-click-of-death/>>url:https://acsdata.com/hard-drive-click-of-death/]] | ||
| 14 | * Hard drive failure warning - the HP BIOS gave a warning that the hard drive was in danger of failing and should be backed up; no known remedy, symptom of old hard drives | ||
| 15 | |||
| 16 | ((( | ||
| 17 | __RAM__: | ||
| 18 | |||
| 19 | * Dell Dimension 2400 - was told via light up LEDs that one of the RAM modules wasn't functioning. Removing it solved the error. | ||
| 20 | |||
| 21 | ((( | ||
| 22 | __Motherboard/Power Unit__: Dell Dimension 2400- unlisted LED code implies that either the motherboard or power unit is malfunctioning | ||
| 23 | |||
| 24 | __Bios: __ | ||
| 25 | |||
| 26 | |||
| 27 | * Administrator password blocks Bios changes - either remove the battery or the CMOS jumper (should say CLRPWD or CLEAR or PASSWORD next to it on the motherboard) | ||
