I have a Vostro 460 desktop at my office and an OptiPlex 3020 at home.  I want to buy either an APC; Tripp-Lite or CyberPower UPS ~1500 VA; 900 watt unit.  I want to verify if I need to buy a unit with a pure sine wave output to the power supply, or if I can use one with a modified sine wave for either of these computers.  Based on comments from current owners of each, there are some newer computers that need the pure sine wave and they're more expensive.

Has anyone seen an issue in Windows 7 where my CPU usage goes from 0 to 100 then back and forth, like a sine wave? I had no apps running. If I reboot it becomes normal again. Ive tried to replicate what I was doing when I noticed it but nothing was found. This has happened 3 times in the last week. A pic of my Task Mgr illustrates.

hi and welcome to the forums

if you download this program and run it you will be able to see in very concise view all your running processors Process Explorer v15.13 By Mark Russinovich

LINK >>> Process Explorer


Ever wondered which program has a particular file or directory open? Now you can find out. Process Explorer shows you information about which handles and DLLs processes have opened or loaded.

The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.

I'm looking at the Resource Monitor, accessed from Task Manager, Win7. I am watching disk activity. I see mostly green sine waves, but one drive also has a blue sine wave. I can't find a key to tell me what the blue wave means.

Blue wave at top of graph, often spiking down to near bottom. Is this i/o errors? Don't seem to see it on other drives.

I am trying to use this device (WD Elements 107C, 1.73tb partition) for my System Image backups, but back up is dog slow. Ran 4 hours over night and only got <100mb of 400+mb. Stopped backup. Ran virus scan and AVG found/fixed multiple occurrences of Tracking Cookie Serving-sys.

I am running SlimCleaner Shred to remove the incomplete backup. It's also running dog slow and seems it will take another 4 hours to complete the wipe. Blue sine wave going nuts.


PS shred done; about 4 hours. Multiple crashes of BSvc Processor
I can't believe it takes 4 hours just to write 100mb of random data to an hdd. I've shredded multi-gb areas in far less time on other hardware.

My APC battery backup UPS needs a new battery, and I'm considering getting a new unit, as mine is approaching 5 years old. I've been reading that standard UPS devices put out a stepped sine wave that can cause issues and possible damage or reduced lifespan with newer Active PFC Power Supplies and LCD monitors. Cyberpower make some that output a "pure sine wave" that is supposed to be better for PFC hardware. Is this really an issue I should be concerned with?

There are 2 UPS units from Cyberpower I'm looking at - 1 has 12 outlets which gives me 2 more than I currently have, which I could definitely use. But it only puts out a standard stepped sine wave. Then there's a similar one with only 10 outlets that outputs a "pure sine wave". Is it worth getting the pure version and losing 2 outlets, or is it not as important as some are saying? I want to do what's best for my equipment of course, especially because I tend to get random power outages for anywhere from a few seconds to a few minutes fairly often - enough to warrant owning one of these units.

A:UPS advice - stepped sine wave or pure?

You really don't need to pay that kind of money. A "pure" sine wave is no better or worse then a stepped sine wave. Not to a properly designed power supply. A properly made power supply filters the incoming power and filters the out going power. In either case the power from an APC is cleaner then what is coming from the Mains directly.

So here is my advice. Forget the sine wave nonsense and get what you can afford that gives you the backup time you need.

So I bought this laptop 3 days ago. It seems like it has a charging problem. It sometimes charges when I let the laptop in sleep mode or close the lid. I sometimes get a full charge but then, when I'm using it, it just stops charging for no reason. To "force charge" it, I discovered that if I first unplug the charger from the laptop itself, then disconnect the cable from the power brick, plug it back in the laptop and connect the brick back again, it seems to charge for around 4 more minutes. I tried updateing the BIOS with the support from the official Lenovo support site (this one) but it does not work. I heard about the removing the battery and pressing the power button but I can't remove the battery.  The power brick and charger are original and seem to work fine. Should I try buying another charger? Please resond to this as I'm desperate. Thanks much !

In December of 2015 I bought my daughter a Lenovo 300-15ISK IdeaPad. In many ways it was a good laptop, but it wasn't durable and I wouldn't buy another one. After 5 months (May 2016) part of the housing around the power connection was broken. Because of this the power cord wouldn't plug in all the way and the IdeaPad wouldn't charge. I took it back to where I had purchased it (MicroCenter) to be repaired. I was told that this type of repair was not covered by the warranty, and the price they quoted me was over $300 (about 3/4 of what I paid for the laptop). I was upset that the repairs weren't covered and that they were so expensive. Other places near me had similar prices for this repair. Luckily I was able to jury-rig a solution so the power connection would stay in place and the IdeaPad could be plugged in and charged. My solution lasted until late 2016 before I needed to adjust it again. That 'solution' lasted until this March before it failed again. This time the power connection became detached from the interior of the laptop. So I opened up the laptop in order to fix it again. This IdeaPad was clearly not designed to be repaired -- opening it up was an adventure which strained my abilities and patience. I was able to reconnect the power connection and reclose the laptop, but the IdeaPad will no longer start. So I am left with a bricked IdeaPad, a poor opinion of the durability of Lenovo products, and a worse opinion of Lenovo warranty terms.

I recently purchased a Lenovo Ideapad 110-15ISK, Model 80UD0017US, and would like to purchase a 2nd power adapter as a backup. I saw in the hardware manual that there are several part numbers listed, and the specific ones on my adapter are:45w AC Adapter Model Name: PA-1450-55LLLC P/N: 5A10H42923 In looking for the part online, I saw several on eBay and Amazon with the PA-1450-55LL reference, but at least one seller mentioned that the size of the connectors aren't always the same. In the hardware manual I did not see a reference as to the connector size (ie 4.0mm*1.7mm), which is the connector size reference I saw by one seller. Does anyone know the connector size on this power adapter for my model? Thanks,Kim

Didn't realize the laptop was unplugged and went completely dead sitting there for a month. Went to plug in to power up and nothing. Thought maybe cat chewed on charger cable and tested it and was only pulling 4v vs the 20v it's supposed to but tried new charger that Lenovo sent and still nothing. I've heard battery could be un-chargeable if left to completely die and sit for a while but still don't get why laptop won't boot up when plugged in.  Am I dealing with something else internal in addition to a dead battery?

My laptop LCD has been out for awhile and I've been using with an external monitor, but I decided to fix the LCD so I ordered a new LCD screen for it. The lcd screen arrives, install it and picture still doesn't show up. I then thought maybe I just had a bad cable from motherboard to LCD so I replaced that.. still no luck.

I can see a faint image in the background, but it's very dark. Same with my original screen.

What's odd is before my original laptop would show a just scrambled picture of black and white-- which is why I originally thought it was LCD.

What would the next step be? To order a inverter? Do the symptoms above sound like it's a bad inverter?

I guess this can go in here since it is kind of hardware.

I am looking into buying a DC to AC power inverter to use in my car so I can watch DVD's on my laptop for long trips. I was wondering if anyone has ever used one of these, and how well they work.

I am planning on getting a 400 or 600 watt one. And I just want to run my ibook off of it.

Any personal experience and notes is appreciated, as I would like to get one soon.

A:Questions about DC to AC Power Inverter

Really need one that powerful for just a laptop - or are you going to run something else off of it. Now I'm not real sure on this but I've seen it with car amps, if you run something that powerful you could need a better alternator than a stock one? I had a friend once who when his camero would idle you could literally watch the voltage on the battery decrease, he had to actually drive to keep the battery charged with his speakers going.

Maybe Stormbringer will have a real answer.

Hi guys,

I'm working on a Toshiba Satellite A105 laptop. The laptop suddenly went dark while in use and now the screen stays dark. In a dark room, with a flash light on the screen, you can kind of make out a picture. I wanted to confirm that this is most likely a power inverter issue before ordering the part. If anyone could help i'd really apprecaite it, thanks!

Here is the solution for anyone interested: As I did some troubleshooting I found that the screen had a pinkish hue which an article mentioned that that usually means there is a problem with the BULB, not the INVERTER. What had me confused is that unplugging the cable from motherboard to inverter brought the bulb on for a second, but unplugging the BULB from the INVERTER did not bring the bulb on, so I thought 'maybe it is the power inverter.' I then took out the LCD monitor from an old dell laptop and hooked it up the the bad HP laptop with the HP'S POWER INVERTER to rule out whether it was the inverter or the bulb. Monitor came on just fine, which means the BULB WAS THE PROBLEM AFTER ALL, otherwise the bulb would flicker just like the bulb from the hp laptop did. Cheers!

I have an HP DV9000 which had no picture on the LCD. Well, it had a picture, but it was very, very faint as if the back lights were dead. Works fine when plugged into VGA or if you squint/shine light to see the actual screen.

So I replaced the screen with my friends old screen from the identical model, assuming the backlights are part of the screen assembly. Apparently not, because it didn't take care of a thing.

So then I figured it must be the power inverter. Replaced that, too, and exact same problem.

What could possibly be wrong? I know how to replace the parts, I did it right. I can still faintly see. Is the backlight a separate part from the screen? Why else would I have no light at all? I know his screen and inverter work fine.

A:Screen and power inverter replaced, still nothing.

Is the laptop motherboard supplying the correct operating voltage and dimming control signals into the backlight inverter?

And yes, the backlight lamps are built-into the LCD panel itself. They have their own power cables and connectors for attaching to the inverter.

Working on a client's problematic laptop...it is a Dell Inspiron 5105.

Laptop was having problems with being unable to power on, and with a darkening LCD when it did power on.

Disconecting the touchpad fixed the power-on problem.

However, the LCD continues to malfunction. I can't tell if the problem is with the inverter, the CCFL, or the LCD itself. The symptoms are as follows:

Sometimes, the screen works fine.
Sometimes, the LCD comes on, but the backlight does not.
Sometimes, the LCD does not function at all.
Video out to a CRT monitor works fine.

There seems to be no way of predicting whether the LCD/backlight will work or not. Just, sometimes it does, and sometimes it doesn't. I've checked to be certain all the connections are secure...

Unhooking and rehooking the connections seems to make little difference. I've reseated the inverter and CCFL, which also seems to make no difference.

Any ideas as to which of the four--inverter, CCFL, LCD or (detachable, ATI) video card--is the problem? Or know how I could determine which it is?

As mentioned before, the computer would not boot reliably until the touchpad was disconnected. Is it likely these two problems are related somehow? I've been assured the laptop did NOT take a lightning strike, but i have only the client's word to go on for this.

I want to be able to power my laptop (Inspiron 600m) in the car, and I have read some suggestions, both in this forum and elswhere, that say that a power inverter is a better deal than an auto/air adapter: inverters are cheaper (under $50), will definitely allow the laptop to charge (which  some auto/air adapters won't, for some laptops), and more versatile since they can be used with any appliance within the inverter's power limits.
But I have also read a couple of things that make me wonder if the inverter is a good idea for a laptop:
1) The cheaper inverters put out a modified sine wave, rather than a pure sine wave. (Pure sine wave inverters are much more expensive, over $100.) A couple vendor websites I have seen say that some laptops won't work properly with modified sine wave input, and to check with  the laptop manufacturer. Does Dell say whether or not Inspirons--specifically the 600m--will work with a modified sine wave?
2) At least one inverter was described by the manufacturer as "much less likely" than a generator to damage sensitive electronics. Does that mean there is still a reasonable danger of damage to a laptop with an inverter (compared to when plugged into a wall outlet)? And can this danger be reduced by using a surge protector?
Finally, if any 600m users have used an inverter and can tell me whether it seemed to work fine or not, I'd like to hear it.

A:Dangers of using power inverter to run laptop?

1) You definitly want a pure sine wave inverter - Dell will probably only sell your their air/auto dapater.2) As long as you get an intervert properly rated, theres no significant danger - worst you can do is kill the power brick. However, the rating you'll need is about 3x the draw on the power brick. So,, for example, if you have a 65W adapter on your 600m, you'll want a (3x65=)195 = 200W inverter to be safe. Otherwise, the spikes of power that are pulled by the brick will overload the inverter.

A:ACDelco 100W Power Inverter

I've been using a ninety-five-watt version for about a year now with my Averatec loptop without detectable adverse effects. Mostly, I use it for charging; but, I have on rare occasions used it to run the system.

To be sure yours in sufficient to run the laptop you could monitor the state of the laptop battery's charge to see if it looses, gains or stays the same.

Example: If your laptop needs 130 watts and the inverter puts out 100 watts, your battery would slowly drain and the inverter would run hot and maybe fail after a while.

Frankly, I don't undertsand why so many people spend a hundred dollars or more for a twelve-volt power supply they can plug into a cigarette lighter when they can get one of these inverters for around 20 dollars or less. I got a package of two nintety-five-watt jobs for $20 at Sam's Club. That's only $10 each.

Hi guys,

I recently posted about trying to troubleshoot a power inverter vs a backlight. With some troubleshooting and help I was able to trace it to the backlight.

Now I've run into a slightly different problem. The screen is black (very dim and even looking at it in the light its hard to see the icons but you can very barely make them out). When I press the standy switch by the monitor it flashes on for a second with perfect colors (NOT purplish like in most ccfl bulb issues).

I took another ccfl bulb just to hook it up and the bulb did the same thing, flickers on and off. I hooked the laptop up to an external monitor and it works just fine (if i press standy I can see it going into standby on the external monitor).

I would say it is the power inverter at this point but would like a second opinion Thanks!

I am looking for a backup solution for my desktop computer (read as: tight budget) which can notify through a software interface about time remaining till batteries run out.

I am trying to run a server on this machine which I'm planning to use to give a demo to some parties from remote location. So basically this desktop will be unattended. I have written a small utility to gracefully shut down the server in case of power failure so that it doesn't look as though it crashed . And this utility needs to read the time remaining till total shutdown from somewhere. So I am looking for a budget backup solution which can provide me this data. (It is doesn't need to log it or so, I'm just happy to scoop it from its process memory if I have to.)

I'm about to go on vacation with my family and decided to bring my laptop along to keep myself entertained on the long car ride. My laptop only has a 4 hour battery and it's an 8 hour trip. So I bought a 12V to 120V power inverter so I could plug it into the cigarette lighter to power it. However, I noticed that the cigarette lighter port provides 120W of power and the inverter is 160W. My laptop only needs 90W to run (according to the manual). My question is: is it safe to use a 160W inverter when the power port only provides 120W? Would I just get the reduced wattage instead of the full 160W or will something fry when the inverter tries to pull 160W out of a 120W outlet?

Thanks to all in advance.

I have a Toshiba Laptop... A week ago, my screen has started going black and coming back. Just two days ago, my screen went black and did not come back. I thought my screen was dead but then I figured that the back light of my screen was gone because when I look at the screen carefully, I barely see the things on my desktop....When I turn on my laptop, I can see my screen for 3-4 seconds, then it goes black again. Same thing happens when I log on after log off... It again gives me the light about 3-4 seconds after just logging on, then it goes black again. I finally opened up the screen, and found the display inverter... and it again gives me the light 3-4 seconds after I plugged out and plugged in the inverter cable. I am not sure whether the problem is the inverter itself of the inverter cable. I really need help.

A:Distinguishing between display inverter and inverter cable problem.

It sounds like the inverter may be sensing an overload on its output(s) and shutting down after a few seconds. Some possible conditions causing it could be 1) the backlight lamp(s) failing, 2) arching of the inverter output cable to itself or the frame of the LCD panel, or 3) a failure of the inverter's overload sensing circuit that makes it think it is being overloaded, when it really isn't.

WARNING: Use extreme caution when working around a CCFL inverter with power applied to it. Portions of it will have hundreds of volts of electrical energy on it. You could receive a nasty (and possibly fatal) shock if you come in contact with the high voltage.

Hey guys, I have a following problem: I run windows and linux on my notebook. On windows I can activate 'energy saving mode'(chargng only to 60%) in the app Lenovo Vantage (lenovo companion's new version). And every time I turn my notebook off (no matter if I'm using win or linux) and take the power cable out, the saving mode is resetted and after pluging in power cable the notebook will charge to 100%. I don't wanna this because I work almost all the time on power cable, I want to conserve my battery. So my questions are:1 what is wrong? How the power saving mode can be set permanently?2 how to turn saving mode on linux ubuntu (I'd like to move to linux, no need to use windows anymore, only energy saving keeps me using win) I'd be so grateful if some of you answered, I've been not happy with this problem for almost 2 years and now found this forum and decided to ask for your help

A:Power to a Micro Wave

Probably not the forum you want to ask that question on. This is a computer forum. But in any case:

I'd buy a uninterruptable power supply that can help prevent spikes and undervoltage, then run the microwave off of that. I don't think lowering the microwave's power from 1-10 does anything for what you want. All that does on every microwave I've ever used is runs at 100% power for a few seconds then runs at 0% power for a while. The amount of time spent at 100 or 0 depends on what level you set.

Please help it worked fine for a while  after my daughter knocked it of the side but now it won't power on
I've tried different power adapters and still does the same thing
No power makes it to the computer at all, the yellow/ green light on the power transformer just goes out when it touches the computer  is there a safety switch on the mother board ?? I've tried it with everything disconnected

Does anyone have any suggestions ???
