Yes, because airflow prevents the temperature from rising much. You need to look at your power bill and see the billing structure and what billing tier you're on. PG&E charges as much as 40c/kWh for major power hogs to discourage conspicuous consumption. At the national average of...

If it won't even show in BIOS it has to be the firmware, right?

The Centronics 50 they used in older SCSI system is confusing in this same way

Actually, it may just be firmware. ST#####AS made in 2008. It's a Barracuda 7200.11. After doing some web search, this model apparently had a serious issues with firmware failure causing the drive to become totally inaccessible. I never dropped it or knocked it over. Was working just fine...

It was working just fine until last night. I realized I couldn't access my drive today, so I rebooted the system and still no go. When I plug the external drive in, it would spin up, then it would click several times and the spindle turns off. Computer does not recognize the drive at all...

Where do you live? Many European countries require power factor correction as per IEC1000-3-2. It can either be passive or active type. Passive type uses large steel core reactors in harmonic filtration process and they make audible noise at line frequency. If you're in one of those countries...

Double check the board manual for the location of motherboard power-button header and PSU connections. If it still doesn't work, you may have a board-PSU "power good" signal timing incompatibility. My older Gigabyte 7DXR and an Antec EarthWatts won't power up at all with EarthWatts 500W...

So, many users were not convinced it is not a counterfeit. I just found out for sure that is is definitely counterfeit. It was returned to HP for authentication and I'm told it's definitely a fake.

HP responded. They believe it is counterfeit based on the same pictures I submitted them. The Corporate Security office in Houston, TX, USA responded: "From the pictures attached, it does appear that the product you purchased is counterfeit. We have had reports of some counterfeit power...

Do you have close up pics of guts of known genuine adapters that came with a new computer and not as an accessory on eBay or some website? And somehow skip an input RFI reduction choke? Many of the SMT components are not even lined up correctly and some are even noticeably floating. I've...

Could a genuine HP have soldering quality that bad? There was a whisker of wire sticking out output cord where it enters the holes at circuit board. There are huge blobs of solder on the board and signs of component legs being trimmed by hand using hand tools.

I lost one of my adapters (had one for home, one for taking it to places and stayed in my bag) and I bought one online, from a vendor called www.newmp3technology.com Update: August 2010: From the way it looked inside and out, I believed it is counterfeit. It was sent to HP for...

The programs can read something obviously wrong and you know it's wrong like a ladder missing an entire rung, but accuracy is not known unless you compare against a calibrated meter.

It's the same idea as P3 serial # based identification. iesnare is a software based tracking that generates a key based on your hardware configuration allowing its subscribers to identify and compare you against their database. I blocked iesnare in Firefox. I can erase the .sol cookies they...

No it won't. They both go back to the rail. Unloaded molex connector will provide voltage at the rail. If you measure at the ATX connector, that includes voltage drop in the connector and wires. Remember that on-board sensing is downstream of the connector. If you were to measure the...
