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...

There is no doubt that compared to hard wiring, added connectors add resistance to path, which maybe compensated by heavier wires. Just how much depends on the specs of the connector and durability. (i.e. SATA internal connectors vs eSATA connector. Latter is expected to have MUCH more...

Actually, I believe UL listing is void too if it is used for outside of intended purpose, i.e. your typical power cord won't explode if you were to hook it up to 600v, but it would not be UL compliant if it was used at 600v. NEC often mandates the use of CSA/UL rated components and while...

Measure by sticking the probes into the motherboard 24 or 20 pin connector under load. Molex with nothing attached to it only sees voltage at the power supply's rail. Falling out of ATX specs can happen if the wire from PSU to connector is too thin for the length.

Cut and splice. I only had 5 molex connectors on my 250W Antec PSU, but needed another connector for the video card. I cut one of the two floppy connectors off, then I spliced in a string of three molex connectors I cut off from a Ultra brand PSU.

The newer plastic case UPSs are similar in my opinion. The general trend is that newer UPSs have smaller battery capacity per VA capacity, so it might look powerful at the store, but have an absurdly low run time. Big numbers sell and batteries are expensive to make and expensive to ship...

It is a code violation... NEMA 15-R receptacles are only rated for use up to nominal voltage of 125v. Not 250v.

I in fact have an ATI Radeon, but Catalyst doesn't show utilization data. I looked around in the control itself and on the web and found nothing

As far as the error I was referring to 420v that was shown on Provantage link. That product does seem very strange. I can't say I've ever heard of anything like that as feeding 240v to a normal, NEMA-15R 120v outlet is like asking for a disaster should a normal 120v appliance get plugged...

Unfortunately, surge protector is line voltage specific. A 120v rated surge protector is rated to clamp (basically shorting over voltage to ground) at 210v peak (normal 120v line is peak). A surge protector rated for 120v will burst into a flame if connected to a 240v source. The clamping...

Is there a software that allows GPU utilization like we can see CPU utilization in Windows task manager? I'd like to be able to check on graphical tasks the computer is performing is being handled by video card or not. For example, if I'm playing back H.264 item on YouTube, and have...

I got an ATI x1550 sold as Diamond Stealth 512MB AGP for my older desktop. It has H.264 decoding capacity, but apparently hardware acceleration of H.264 videos in Flash platform is not supported with the new Flash 10.1 I mainly use Flash based contents and don't play FPS games. So, what...

Every couple of weeks, I have to change my WiFi channel. I would be surfing the web fine one night, put it on my night stand and go to sleep and when I go to use it in the morning, my access point shows 5/5 signal strength, but it would not connect at all. When I click on the access...

Well, I took out the Adaptec DuoConnect and installed a Belkin USB2.0 card,which also uses the same NEC chipset and now the transfer rate is ~22MB/s I have no clue why though.

I can understand a shared bus slowing down if multiple devices are operating, but why would a hub with a printer and an unused memory card reader slow down the other port to 10MB/s from 17MB/s ??? I'm running WinXP SP3

I have USB2.0 ports on my computer through an Adaptec Duo 3020 Firewire/USB2.0 combo card. I just added an external hard drive and after being infuriated by how slow it is, I discovered the mere presence of other devices slow down every ports. The "mass storage device" on far right...

It could just be a glitch in BIOS. The Abit BE6 had an issue with keyboard LED staying on after a power down and there was a BIOS addressing this issue.

It's inconsequential. The power usage of UPS is not dependent on load. It's a fixed parasitic loss unless you happen to have a double conversion UPS, which the APC SmartUPS is not. After a certain point, runtime vs load becomes non-linear. i.e. you might get 20 minutes at 60% load, but...

When you make the parasitic losses, it's important that you let the battery charge overnight, not until just 100% is read. After battery depletion, battery will continue to charge long after "100%" indication is read. This has to do with the way charging is done with lead acid batteries...

The OEM battery for APC is often made by CSB and if you've ever seen it, it's even marked CSB. Gruber runs a full service UPS repair shop too, so they have batteries constantly moving and it's much cheaper to just have a few more on extra and use use the oldest one first, it's easy to keep the...

Is this a problem with 2.4 GHz mouse in general or just some models?

Why do you want to? Unless the fan is symmetric and specifically designed for flow reversal, it's not going to provide a good air flow when it is spun backward.

I have a Logitech V450 laser mouse with 2.4GHz radio and it's constantly having problem with poor connection. Even after relocating receiver to different USB ports, it continues to randomly fail to register clicks and jumpy pointer. I didn't have this problem with my 27MHz band Logitech...

The price of lead has gone up quite a bit, so you'll pay a lot more than you did last year regardless of where you buy. Batteries Plus is quite a rip off, although I do take spent batteries there to have 'em recycled. So far they haven't objected. I get my batteries from Gruber Power...

The Earthwatts might not be the best choice for an older computer. It has an issue with PG timing issue and it would not turn on at all on one of my computers. Antec Earthwatts or any PSU + my other PC = fine Antec Earthwatts + this PSU = no, but other PSU = fine. So, I'm using a 250W...

Ok, I skimmed through the thread titles before posting but couldn't find anything that seemed to match this one sorry
