Static Electricity

Question: Static Electricity

So, as I lie on my bed and move around, I build up static electricity which is released as a static shock when I touch my computer.
...this is bad for my computer, right? Should I make an effort not to do that?
Thank you in advance.

OUCH !! Static discharge can kill ram, eprom and other onboard chips.

Attempt to avoid it by

touching a bedside lamp base (metal) before touching the laptop
get out of bed, walk to the door and touch the door handle

I keep getting a spark of static electricity when I touch my laptop. I have changed outlets, power strips, and even laptops. It actually shuts one of my lap tops down. It is in an office, so I have no control over humidity. How can I stop the static? Thanks in advance for your help.

When putting a computer together, is it necessary to have a static wristband to protect against static electricity and harming any components? If not. what are some steps to be cautious on this measure?

Answer:Static electricity?

I'm told if you touch the case before you touch the components, you'll be safe.

I use a static strap... but thats because I have big clumsy fingers and its just too dangerous for me...

I have a computer lab at the campus i admin. It seems that there is a problem with static and im looking for a way to remedy this. its going to cause a lot of problems so im trying to find a quick way to fix this. every computer in the computer lab reboots when i even touch any metal on the computer, specifically the usb port with a flash drive or even my finger, if im not grounded. when i touch the metal on the desk then touch the usb port its fine. any ideas how to get rid of this problem? students use this lab and i highly doubt any of them will actually find some metal to ground themselves before using a flash drive.

I tried Googling and searching Sevenforums for methods on how to ground yourself without a wristband (I don't want to buy one). So basically all you have to do is touch the metal part of the case with your hand and your screwdriver before touching another component?

Thanks for the help.

(oh, does anyone have a up-to-date guide on how to build computers?)

Answer:So, how would I deal with static electricity?

Make sure you're touching bare (unpainted) metal. You could also google for articles on how to prevent ESD (electrostatic discharge.) Some other things you should do are here:

What is ESD or ElectroStatic Discharge

As far as building your own computer, the basics haven't changed all that much over the years. You still need the basics like a case, power supply, motherboard, hard drive, etc and they all have to be compatible. What has changed over the years are the technological advancements like SSD vs HDD, terabyte drives vs gigabyte, number of cores in the CPU, and perhaps most important of all . . . how will you be using the computer? I think it's safe to say that if someone is going to do online shopping, send/receive emails, and maybe watch some videos or listen to music, his computer requirements will be less than the person who does 3D drafting, video editing, hard core gaming, etc. Couple of guides that might help:

How to Build a Computer from Scratch: The Complete Guide

Step-by-Step Guide to Building a PC - New-System-Build - Homebuilt-Systems

And I'm pretty sure that others will jump in with other suggestions on what they think you should consider.

Hello all!
 
 
I seem to be having an issue involving static electricity. Whenever I touch the front bezel of my PC and give it a shock it will restart with a BSOD. It doesn't seem to do this anywhere else on the case afaik. I checked the outlet and the surge protector and both are giving ground so that should be fine. My front bezel has nothing attached to it whatsoever, no wires or anything. The case I have is the Thermaltake Core V71. Any ideas as to why this is happening?

Answer:BSOD from static electricity

I guess it's the metal grille area that you touch and the static discharge goes to? The metal bezel portion of the front panel would have some means that is supposed to be grounding it to the rest of the case - perhaps a tab that presses against the case as it is assembled, or a screw that passes through from inside the panel. It would seem that however this earth connection is achieved is not making contact to ground the bezel. The static charge will be jumping to ground by another path, probably wiring between the front panel and the mainboard, which will shock the mainboard circuitry & give the blue screen. Finding how the earthing should be happening, and correcting the bad connection (scrape away a little paint, tighten a screw, maybe even reconnect a little earth tab that came apart) should cure it. But not knowing the case, I can't give any more specific details than that, sorry!

Having some weird problem with my computer I just put together last night. In my main computer my mouse works fine and there are no issues but with the computer I put together, every time I get up off my chair and I am charged with static electricity, my mouse light blinks and even goes right out especially when I touch the metal on the chair and the mouse loses power and I am not even touching the computer or mouse or anything near the mouse but the chair. I tried a different PSU cause I thought maybe that might be causing it and unplugged hardware and it still did it. Also want to mention that I did a stupid thing and I forgot my HDD wasn't plugged in and plugged it in while the computer was on then it shut off and I turned it back on and there was display but then it went blank or it was already blank (can't remember) so I did a hard shutdown and unplugged it and plugged it back in and it worked ok. Could there possibly be some sort of grounding problem?

Heres the story. Had a friend go to turn on her computer, and as she was hitting the power button, she claims to have been shocked by static electricity.

Pushing in the power button seems to send power to the computer, mobo gets power, computer sounds like it boots up, even the temp dial in the front glows and appears to be fine.... however, nothing ever displays on the monitor.

So far, what I have done is checked that the monitor is fine, so it has to be something with the computer.

I have replaced the motherboard, RAM, and videocard (because I don't know whats wrong) and the same thing still occurs. Powerup but nothing on the screen.

My only guess now is that it is the power supply. Which isn't too hard to replace, but just wondering what else I can do to check whats working and whats not working.

Thanks~~

Answer:Static Electricity, Busted Computer Help~

could be the power supply but my thoughts are that it is a grounding issue with the motherboard circuits contacting the case. that would explain your friends shock

When I took my computer for repair, they guy did not had a pci adapter, so he took out my 8800 GT and basicly touch the whole top part, and I asked him if that was okay, and he said that it is very rare for a new component to stop working because of static. Is that true? or does it only apply on the graphics card?

Answer:New components are prone to static electricity?

I've never discharged static on any of my components...and I handle them all over. Just ground yourself out before you touch any components (touch any unpainted metal surface to ground yourself out). I've worked on tons of computers, and just make sure to eitehr touch the case's metal, or the metal legs on the tables I work on.

disclaimer:
i'm a little embarassed to even have to ask such basic questions. however, it seems easier to find information to solve technical questions than to find information spelling out what most people just know.

background for static electricity questions:
i've read that--
grounding is important when working on hardware. this can be accomplished with an antistatic wrist band and a cardboard box.

questions:
1. if we open a case on a wood kitchen table and work while standing on a tile floor, is this sufficient?
2. is there anything i should know about the tools we use? i use chopsticks to hold things out of my way, for reaching things or to help me get the cases apart when they don't just have screws. is this okay?
3. i use a regular plastic screwdriver when i need one. do i need to do anything to ground it?

about cleaning:
canned air seems to be the choice. is it the only choice? can i use a clean paintbrush, a microfiber cloth, or a magic eraser on parts. is it a HUGE no-no to use the dyson?

some of the computers my son and i have been working on are very old, most have been stored in garages. while they are working fine without much cleaning, it goes against my instinct to put anything back together without wiping it down first.

for the record, we aren't running a business. it's just something fun to do and i don't want to put a lot of funds into it.
 

Answer:Static electricity? cleaning dust?

If you touch the metal of the case, you are at the same potential as the case
Therefore you cannot harm the parts (unless you build up Static Electricity by moving around again.

So as the title suggests I'm having a problem with static electricity powering on my computer. If I touch the outside of the case it will sometimes discharge and turn the system on. I have a few questions about this: one being is this harmful to my computer? My computer is grounded through the PSU which is plugged into a surge protector. The second being is this odd? Is this a common occurrence? Or might I have some sort of wire touching the case that shouldn't be? I've checked and I don't see anything out of the ordinary as far as wires are concerned.

If someone has some suggestions or help I'd appreciate it, thanks.

Answer:Static Electricity Turns On Desktop

Does this only happen in winter, or other dry times or is it all year 'round? I would consider getting a humidifier for the room your computer is in. Although, it is grounded yes, static electricity can have an adverse effect on other parts besides the PSU. Before you touch your computer, try grounding yourself on a door handle, light switch, etc... to discharge any residual static in your body.

I am a great believer in always wearing an earth strap when I go inside a PC. Some on this board have the view that this is not necessary!
Lets look at what static electricity is! It is simply high voltage electricity with no current. It can and often does reach very high voltages. When you get that spark between your finger and a car door that can be measured at about 500v.
Different people generate different levels of static even though all other factors may be the same. You can have two people dressed in similar clothes next to each other at the same bench with wildly differening levels of static being generated! Certain atmospheric conditions create differing levels ie humidity, temperature, barometric pressure and a multitude of other conditions! Personally I generate a fairly high level of static as everytime I walk past our home radio we get quite severe interference. So my view is that as there are so many variables in the generation of static electricity it is better to err on the safe side and always recommend the use of a good earth strap. Better safe that sorry. I think it is encumbant upon all here who affer their advice and help to take a resposible attitude towards this problem and recommend the use of a strap but I would be pleased to hear what others think!

Answer:Static Electricity and earth straps

I have moved to using the "earth strap" (even though I haven't heard it called that) when working on PC's. I have fixed many a computer by grounding myself to the case by holding/touching the metal casing and have had no issues with it. I have heard of people never using one and never having any problems. but.... better safe than sorry. it is good practice to use it so that there is no doubt that the hardware is safe.

Edit: also, another reason for using it is that I have started working on laptops more and there isn't a lot of metal to ground yourself to. so it is easier to ground if you are wearing the strap.

I have known it as an anti-static wrist-strap.

I admittedly don't know much about hardware... so he goes nothing.

A friend of mine built a new PC for me. Brought it home last night and everything worked fine.

Today I was installing some software and went to eject a CD when I touched one of the face plates on an empty bay. The guy who builted it said the face plates were brushed aluminum.

When I touched the face plate, I heard and felt a crack of static and the computer turned off. When I turned the power back on, only the fans and the purdy lights on the outside of the case kicked on. The hard drive did nothing, and the power light on the front of the computer did not light up. I'll have to look when I get home again, but I believe there was a green light lit up on the motherboard.

It seems to me that a small bit of SE wouldn't be enough to fry something...or if it is, that the computer would be built in a way to prevent something as common as SE to have an effect when it hits the case... am I wrong? What did I kill here? Is there anything I can do to help diagnose the issue?

Thanks all...
 

Answer:Static Electricity Fried my new computer?

SE is literally hundreds of thousands of volts!!!

I once went to turn the power off on my computer and static electricity shut it down before I even pushed the button. I tried to turn it on afterwards and it took a couple tries, but it eventually turned back on. You need to make sure your system is properly grounded.

Answer:Static electricity from our body could kill motherboard?

Hi n0tepad,
Unfortunately that is true. Thats the reason every component has a warning to use an ati static wrist strap when assembling or handling, or to discharge the static by touching the metal portion of the chassis when installing,assembling,or disassembling. You will get away with accidentally shocking a component more times than not...but it can damage or ruin them.

Hello, Gods & Goddesses of Geekdom,
I have a Dell Inspiron 8600 (Win XP) that I got last year. Sometimes I attatch an older Dell ergonomic keyboard (SK-6000) (using some cables from Radio Shack; don't know what info I need to tell you 'bout with them) to make typing easier. But invariably the application freezes; it will repeat a symbol (usually ````) until I alt+F4 and then reboot.

In searching your hardware forum for "static" the only things remotely similar talked about video cards, and to my untrained mind this didn't seem relevant.

What info should I give to help you geniuses sort out this problem? Or can you tell me right away, "Hey, Grammaw, you can't use another keyboard with that laptop, duh!"?

Thanks to all who can contribute info.

As my screen name suggests, I am very low on the scale of puter knowledge although I can figure out how to do a few things if it only involves point'n'click.
 

Answer:Static electricity when attatching keyboard to laptop

Does the connector look like this?


Or like this?


If it looks like the first picture, you'll need to make sure you plug the keyboard in before you turn the laptop on.

Hi Guys and Gals in TechSpot
Just thought Id add a little side note....When you are going to open your tower or case to reset the cmos, install hardware, etc., I know some posts tell you to unplug the mains power. Just a different variation, Safely isolate the mains supply (TURN OFF SWITCH )but leave the cord plugged in.
Once you have removed the cover, discharge any static electricity you might be holding by touching the side of the power supply which is grounded to earth. Ideally a bonding strap bought from an electronics store is preferred.
I know its a simple thing but sometimes overlooked casing more headaches.
Regards
 

Answer:Static Electricity - read before openning cases/towers....

Very true!

I worked in high tech as an embedded systems developer. I handled electronics routinely. Proper grounding makes a difference. Sometimes, you don't see the static spark, it's that subtle but it can fry a component.

While you're upgrading your hardware with the case removed, it's a good time to blow out any dust built up. That's something else a lot of people don't realize. Excessive dust build up can cause hardware problems, even disable your comp! Take a vacuum or hairdryer and remove all that dust!

Hi Luis and welcome to the community,
 
Try plugging your adapter into another outlet.  If the outlet that it is plugged into isn't properly grounded, that could cause the shock.
 
If this is a wireless mouse with a dongle, it is normal for it to be on if the dongle isn't attached back to the mouse.

Hi all, I originally placed this in someone elses thread by accident a couple of days ago, but really should have opened my own thread, apologies to the other member :

Earlier today I had the pleasure of listening to sereen music through a pair of ex71 bud earphones via the audio jack of my back up Inspiron 1100 laptop with SigmaTel sound card. My listening was disturbed by the sudden onset of pins and needles in my left foot.

I figured stomping my foot on the floor would get rid of the pins and needles without necessitating the need to disturb my listening by getting up and walking about.

To my dismay, whilst plodding my foot away, I managed to get a sharp static electric shock in my ear through my left earphone. But there was double trouble. Not only did the shock in my ear kinda hurt, but the music had turned to scratchy and robotic high / mids and completely distorted lows, with a loss of volume. Unbelievable, as only two days before my 6292 had given up the ghost :dead: and was in the service agents.

I had tried reinstalling all software and reboots for a couple of hours to no avail, and wondered if anyone had any ideas on rectifying before I shot off and got a new cheap external sound card (looking for any recommendations here also?)

However, having not had the opportunity to look into any further, the next day I then plugged the laptop in at work, only to notice the OS jingle sounded uncannily familiar. Popping the budphones in, loading the media play... Read more

I just got a w520 with baseline configuration except for the 3x3 wireless card. I have upgraded the laptop to 16gb of ram and added a MSATA ssd. I love the laptop except for one issue: any amount of static electricity crashes the laptop. The laptop goes black, often with some quick graphical errors and then reboots. Simply sliding the laptop across the bed causes it to crash (I can swing it around in air as much as I want). Putting the laptop into the padded (nylon?) sleeve in my backpack will also cause it to crash, even while the laptop is in sleep mode. I have had this issue since I have got the laptop on day one (before any upgrades). I was hoping the issue would resolve itself as a software issue. I have since realized it is a hardware issue I have no control over as it is repeatable even while in bios.  This situation leaves me with a dilemma: Return the laptop and possibly get one from a different model/manufacture, or turn it in for repair.  There is currently a huge thread about the issue and other sudden shut downs with the W520, so others have had the issue. However, given the number of laptops sold, I know most must not be having issues. In that case, sending the laptop in for repair should fix things. However, I have heard that the repair service does little to recreate situational problems and would not see or fix my issue, so I would be better off sending the laptop in as a return.

Answer:Solved: Newb Java Problem - non-static method cannot be accessed from static context

Just an FYI for anyone who might read this thread to find the answer to their own problem.

The solution was to make the method static. I could then use the first variable declaration 9see below) without any problem.

RenderedImage rendImage = myCreateImage();
Though, it still isn't clear to me why the method has to be static.

Hi folks,

This is my first network setup and i am hoping someone can help me with some issues. The setup is as follows:

Router: Netgear DG834GT ADSL

Computer 1: (Known as Maude)

Desktop
Celeron 434MHz CPU
512 Mb RAM
XP Home SP2
Wired to Router
Has USB Hard Drive that i want to use as a central data file storage space for the network.
Computer 2: (Known as Myrtle)

Desktop
AMD Duron 1.29GHz CPU
512Mb RAM
XP Home SP2
ASUS WLAN via USB
Computer 3: (Known as Martha)

Laptop
Celeron 1.86 GHz CPU
512 Mb RAM
Vista Home Basic
802.11g Mini Card Wireless Adapter

Computer 1 is in the living room and is used for email/browsing/word processing/IM and other relatively low demand applications and is the most likely to be switched on, hence the Networked Drive being attached to it.

Computer 2 is primarily the hub of my Recording Studio (grand name for a cobbled together hobby type affair) but is also used for email etc. It is located in an outbuilding but is no more than 7meters from the router and gets signal and link strengths that rarely dip below 50% and more likely average 65%

Computer 3 is my wifes college laptop and is only really part of the network so she can use the printer attached to computer 1 and back up her files on the networked drive.

All 3 computers communicate.

The biggest problem is the data transfer speeds between Computer 2 and Computer 1.

Hello again, forever young MG Whiz-Kids,

I have a portable CD MP3 player by my bed. It has an a/c adapter, plugged in all the time. I leave a morning and night 'subliminal' CD inside the machine, and play it twice a day.
I usually have to eject the CD and rub it over my cotton pillow case and across my arm to try to get static off it. It skips from the static build-up, not from any scratches. Most days wiping it on cloth is enough, but on rainy days like today it seems impossible to keep it from doing that.

Recommend any cheap anti-static cleaning strategy??

I do clean the CD player lens with a dry cleaning disk pretty regularly.

While I'm on the subject, here's another Q : Does putting a paper sticker on the rough side of CD's keep them from scratching or skipping up ? Are they worth the money, time, and effort ?? Seems they get scratched from the top (printed) side easier than from the plastic rainbow side.....I heard the data is actually more near the underside of the printed side than outside the clear side. More vulnerable from above than below...T or F ???

Thanks folks, :wave nice to be back here again....

yours truly,

-scottportraits

Question: electricity

Just curious does a 2.8ghz w/ 600w power supply use a lot of electricity? Should I be shutting it down every day? My electric bill is like $240/month and I'm trying to figure out where its going. I'm thinking AC and I have a 55" TV that my grandmother watches constantly, and I have a 1000watt surround that is always on too. Thats all I can think of.
 

Answer:electricity

If you're AC is running a lot, that's probably, by far, the biggest power drain in the house. And, if the AC is low on refrigerant, it may be running more than necessary and needs to be serviced by an AC technician.

I have no idea how much power that 55 inch TV consumes. Maybe grandma needs to pay part of the electric bill if she wants to watch it "constantly".

Of course, all aspects of power consumption in the house should be scrutinzed. Why do you have that 1000 Watt surround "always on"? And, yes, shutdown your computer at night; during the day, you should probably at least be using Standby or Sleep mode to reduce power consumption during periods of inactivity.

Answer:How much electricity?

Depends on how much time is spent on standby, and whether you have a CRT monitor and what size that is.When all is actually in use, you could be towards 200 - 250 watts..... so a guess would be 4 or 5 hours per unit...... but it is just a guess, and it might be less than that.First posting failed (errored out) so if this is duplicated you know why

My PC has behaved strangely since Dec. 2007. It refused to start Windows on the 1st try. At first, if I turned off the PC and let the main power switch turned on and waited for a while (5-10 mins), it seems that the PC was charged fully and would behaved normally for the whole time U used the PC. The whole scearnio would begin again after I turned off the PC at night and turned it on the next morning!

But these few days, the situation has worsen. Even if I left the main power switch turned on for a few mins, I couldn't get my PC to load Windows on the 1st attempt! I had to reset my PC 2 to 3 times to load Windows. Then after Windows XP has loaded, it seems my PC responded slowly to applications (Internet Explorer, Outlook Express, etc) in the beginning. If I waited long enough, the applications might pop up and run smoothly?! If the application didn't pop up, then I had to kill it and restart again. Sometimes by killing and restarting appliciations, the PC just hanged. Pls help. Thanks!

About 6 months ago my computer recieved a HUGE PROBLEM.. We have spent tons of money on it trying to find the problem, when it turns out that we have electricity problems at our house. When we turn the washing machine or dryer we will get a small surge and the computer restarts. We have just beginning to notice that its not only the washer and dryer we have noticed that when our fridge kicks in it also restarts. We have tried moving to differant location of house, but it still happens. When it restarts it will start loading up again and when everything seems normal it keeps reseting again! We probably will get an electrician to our house. The first time it happend was when i was playing WoW. Now sometimes when I play my games and the disk reader speeds up fast it resarts aswell. I usually wait 10-20 minutes and then go back on. Please has anyone else had this problem?

I propose a simple network with two desktops,one xp and one vista premium.Would I be better to stick wireless network or go with the electrical points in both rooms? Does anyone have any experience of using household electrical points to make a home network? Many thanks

Answer:Wireless or Electricity

Do you mean you intend to network the PCs together just to share files or network them via a router to share internet access?If the latter, then a wireless router will give more flexibility in the future when you need to add another PC or a laptop ('cos you will) :DI use 2 'homeplug' devices to connect my son's Playstation PS2 and the PC in his room to the router downstairs. They were literally plug and play and required no setting up at all.So, in my case I use a wired connection for the PC downstairs, wireless for the 2 laptops and homeplug for the kit upstairs. The wireless signal would have been fine in the boy's room but it was easier/cheaper to connect the PS2 this way.If you add up the cost of wireless cards for your 2 PCs against the cost of the homeplug units it may help in your decision. Of course the homeplug don't suffer with signal 'drop out' if you have a large home or one with thick walls.Hope that helps.

Basically yesterday the electricity went out and since then I haven't been able to boot Windows 7 on my PC, so I downloaded Ubuntu on my laptop and went in to check if the files were ok (without installing Ubuntu just running it from the CD) and it turns out that my RAID0 was gone and so were the partitions on it, I had one for Windows and another for the rest in case I had to format so not to lose the data on my PC.

So what I'd like to know is if there's any way that I can recover the data that was on my partition D, didn't want to format right away because I'm scared that if I did the data would be lost, so yeah, help me out please.
Thanks in advance.

I just remembered too that before my monitor started blacking out, my pc shut off, not going thru shut down the normal way, but as if someone pulled the plug. Well, anyway after a couple times of my monitor blacking out, my computer shut off again, but then actually restarted on its own. A time before this this evening it had shut off itself but didn't restart and when i started it, i should make note that after i had connected to the internet i got a message from norton antivirus that threat protected had detected a worn and stopped its intrusion.

I was working on my pc when the electricity went off. when it came on again i restarted the pc but the monitor keeps flashing on & off. this happens more when i attemp to do some operation on the pc.i cannot check the system cos the monitor wont stay on long enough! i have tried to reboot the pc with disc to put new os on but it wont boot. I cannot seem to change the bios boot order...... it was set to boot from cd anyway. i have tried the monitor on another pc & it seemed to check out ok. so im asuming its the pc.i know some basics but im not a proper tec ! any help would be appreciated for this please !i did put some ddr 1 in the pc but have discovered that this was a different bus speed. would two ddrs running at different speeds do this ? i have been told that all this would do is they would just run at the lower speed.I did take the new ddr out but it didnt seem to make much difference.

Hi!

I'm considering buying a USB hub. My knowledge in electricity is about 0, so I'm not sure about the preferred power specs of each.
So there's that one, 7 ports, with a 12V/3A power adapter.
7 ports, 5V/4A.
9 ports, 12V/5A

The last one has only one port designed for charging, and the rest of them may not be good enough.
From the second one (4A):
To ensure a stable connection, don't use this hub with high power consumption devices (those exceeding a combined current of 4 Amps among all ports) such as some large-capacity hard drives.
This hub is not meant to serve as a stand-alone charger. It is not compatible with iPads or any other devices which have irregular charging requirements.Click to expand...

From the third one (5A):
With an additional port devoted exclusively to charging, this hub was designed with compatibility in mind. At up to 2.1A fast, the charging port max-speed charges smartphones, tablets or even other USB-charged devices.Click to expand...

Are they talking about the amp parameter? The third product says specifically that the special port is capable of 2.1A. So how much do the other ports supply?
I thought the device can provide X ampere total, regardless of how it's divided. (by all ports, or taken by just one)
Is there an amp limit to each port?

What are your thoughts? Thanks.
 

Answer:Questions about a USB hub and basic electricity

You are correct, the total current (1000mA = 1Amp) output of a powered hub shouldn't be higher than it's power supply can deliver.
But some Usb devices don't need the full 500ma maximum current that a Usb 2.0 port can deliver so in practise you may be able to use all the Usb ports on the hub even if they can't all deliver 500ma.

Usb 3.0 can supply up to 900mA per port but here again the total current should not be higher than the hub's power supply can deliver.

Any electrical device will only use the current it needs to operate, possibly a lot less than the power source is capable of delivering. The Voltage a device is rated for should be the same as the source's though.
So a laptop charger that is rated for the correct Voltage and at least the same or higher current output needed for a particular laptop will work ok, the laptop will only take as much current as it needs, even if the battery is removed or is charging.

This is a good explanation of Usb hub current ability :- http://en.wikipedia.org/wiki/USB_hub#Power
Usb ports designed for charging devices can deliver more current, more info on all this here :- http://en.wikipedia.org/wiki/USB#Power
'Normal' Usb ports are 5 Volts but see the table at the above link for some other types.

Please can you help me use my computer so that I dont use up too much electricity, and thus will save money and also not harm environment?

Now, I had been told to leave computer on all day by someone as it is suppsed to be best rather than turning off and on throughout the day.

But what I need to know is what you suggest. Are there ways to set it so that it 'sleeps' after a certain time of no use?

Should I turn it off every time I have breaks from it, however long or short?

I have the lowest speed Broadband.

Any help will do to help me save on electricity bills, thanks

Hello
The electricity jack of my Tecra M2 has broken and the laptop is out of power. Is there a way to fix it without having to use an expensive repairman - considering the age it is not really worth 1200 DKK (180 euro).

Alternatively, which external cabinet is suitable for the hard drive? I've looked at it and have no idea whether it is a SATA or PATA-drive?

Answer:Electricity jack of my Tecra M2 is broken

Have you considered using the Advanced Port Replicator III?

In this way you can power your M2 without going via the DC electricity jack. The existing power adapter will plug in to the replicator and then the M2 docks using power connectors within the shrouded multi-connector on its underside.

This of course assumes that the jack itself is physically broken and/or the electrical connections between the jack and the motherboard. If it is anything further downstream, then the replicator won't help.

The ARPIII can be picked up reasonably cheaply on well known on-line auction sites for as little as 15 stirling (whatever that is in Euros).

I do not know if I mentioned this but there was one time when the internet went out (as it does somethimes here) while my computer was updating and the updating just stayed frozen until the Internet came back on. So ultimately it couldn't even shutdown while the Internet was off. But here's my big worry, what if the electricity goes out when updating. (that happens sometimes here too) is that something to worry about?

Answer:Internet/electricity going out while comp updates

Losing power at any time could cause problems for a computer. The best solution would be a UPS (battery backup) that can keep your PC running when the power is out.

The specification of the UPS will depend on your PC's power consumption. Ideally you'd want a UPS that can keep the power on for at least a few minutes so you can power off gracefully.

I know when installing a RAM, you should first (of course) turn the computer off and unplug it before anything else to avoid damaging the memory module or the socket.What will specifically happen to the RAM if you forgot to unplug the computer?

Answer:RAMs and electricity, and plain forgetfulness

Probably nothing. As far as I know the RAM modules aren't powered whilst the computer is off.

Ok, here's something i'm not entirely familiar with. Maybe someone out there knows the answer to this one.

I'm putting together a linux box (finally) out of bits and pieces of a few old machines i have laying around. I'm planning to use a motherboard that originally was powered by a 200 watt Power Supply and a 500 mhz AMD chip. I recently bought a new case for my new build and it came equipped with a 400 watt Power Supply. Now i'm wondering, is there a such thing as supplying TOO MUCH power/wattage to a machine? I'm not sure how the whole thing works, and i admit i really should study up on electricity 101 to familiarize myself.

Will i have any problems powering my older mainboard with my newer/much more powerful Power Supply? The power supply has the right connector for the mainboard, so that's not a problem. I guess to summarize...

Does the mainboard and peripherials draw (or suck in) whatever electricity/wattage it needs, or does the power supply give a certain amount of wattage/juice to the devices depending on it's own size/wattage? Some basic electricity 101 is needed here. Just wanna know if there's a chance i'll supply too much power to my old board and fry it lol.

The more i think about it... i think the devices draw in what they need. Which means i'd be fine... right?

Answer:New Power Supply + Old Board & Electricity 101

Yes, the motherboard only takes as much as it needs from the power supply, the PSU doesn't force 400watts or watever of electricity into the Motherboard. If you read on the labe, it will even say "400Watts MAXIMUM power" or something like that. The amount of watts is the maximum amount of power the PSU can give out.

My friend is having massive problems with her computer right now, I have suggested everything possible and nothing is helping or she cant do it. I'm hoping that someone will have an idea of what she can do that won't involve her losing any of her massloads of files on her computer. Basically here is the situation:

After the power (electricity) flickered, nothing showed up in the task bar when she minimized things, they'd minimize right above it, and she could move them around on the screen. She restarted it, and nothing changed.. it was still doing that. But that was all that was wrong with it at that point. After awhile, she tried to open Outlook Express, but it wouldn't open, didn't show up on the applications or processes list or anything, and so she tried to do things in Paint Shop Pro, but she couldn't paste anything at all. (Which she also attempted on text documents after that. There was no paste option.) About an hour or two later, Outlook Express finally opened, and it said it was 'not responding' took her about 15 minutes to finally get it closed. Tried opening Windows Media Player, but it said there wasn't enough memory, so she restarted the computer, which took like 10 minutes, and tried again. Still said there wasn't enough memory. She minimized an internet window, and instead of showing up above the taskbar, it completely disappeared.

I had her correctly shutdown her computer, wait a few minutes, then restart ... Read more

Answer:XP programs problem after electricity flickered

Run a System File Check. It will replace any damaged system files.

Start - Run - in the Run dialogue box type "sfc /scannow" and press enter
Do not type the "" and make sure there is a space between "sfc" and " /scannow"

If its done correctly a status window will pop up. You may be asked for the XP CD if its not a pre-installed version.

Takes a few minutes.

The sound only last about 5-10 seconds..and it overwrites what ever is playing on the side of the speaker it happens on


(PC speakers - USB powered speakers - left side static)
Model# Durabrand UC-280

(Surround Sound - Right side static)
Model# Durabrand Ht-3917

(TV - Right side static)
Model# Vizio L37HDTV10A
Hooked up PC = besides the basics, nothing.

Hookups on TV = Xbox HDMI sound automaticly there with HDMI, Nintendo Wii (AV), DVD player (AV)

Surroundsound Hookups = XBOX 360 that comes straight from the 360 suround sound adepter.
PC Wall jack - 1 surge protector all slots full
TV Wall jack - 1 surge protector all slots full
Any ideas? for more details just ask me
im really annoyed by the sound, and concrned about all my electronics.
