I keep my computer plugged in when I'm at home, but my power cord keeps "shutting itself off" and stops charging. So sometimes I check my battery power and there's like 24% left. My battery seems to be holding a charge for now, but my power cord seems to randomly fail. Never in my life have I ever heard of power cords failing-I'm sure it happens but this is ridiculous.
I have an XPS 1330 and my wife has an older Inspiron 6000. The power cord on her Inspiron 6000 went bad. My adapter has an octagonal shape on it so it won't work with her notebook. However, my slim 3 in one travel charger does fit her notebook so we've been using that
I purchased an Acer Aspire 5740 laptop, which I quite like except for the awful beep it makes when the power cord is plugged in or removed from the laptop. Is there any way to disable this beeping sound?
my power brick making a clicking noise and the LED light sort of flickering in conjunction with the noise. Does anyone else have this issue? I'm not sure it's a problem, but I'm worried that it might be.
First post here... Here's the deal, my 600m won't charge the battery anymore and will not run off of the power cord.
The power cord is showing 19.5v which is correct.
The back of the power adapter jack on the mobo is showing about 3.5v when plugged in and the two outside pins that charge the battery are only showing about 0.02v. Is this normal voltage or do you think the mobo broken?
I'm not really sure which of the battery charging pins to check the voltage from and can't find a diagram of it anywhere.
Travelmate 4010. I've had it for about 3 years now, and over the past *thinks* 6 months or so the power cord had been replaced twice because it broke. But it wasn't really the cord itself that broke the first time. Something inside the jack is broken and now the cord (a new one) has to be positioned just the right way so it doesn't switch to battery mode. I use it mostly on my bed, which probably doesn't help, but at one point I had to have it on a desk with the cord taped to the lid so it wouldn't move and kill the battery (which doesn't last that long). I couldn't even close the lid so I just had the monitor shut off after a minute. but I did get a new cord and started using it on my bed, storing it underneath when I'm not using it. After a while, though, the cord started to do the same thing and now I'm sitting here trying not to move on the bed too much so it doesn't disconnect. I'd like to get a new notebook, but I can't afford it.
I have lenovo g 500 (laptop) and everything was fine until today when start my laptop i see black screen with lenovo logo (white color) URL....I have tired to remove the battery with/without power cord but still same.
I have a Latitude E5520 that is having some strange issues. If I have i plugged in to a power cord, close the lid and disconnect the power cord, the unit shuts off. Sometimes when undocking, the unit will shut off as well.
I have checked the power settings and confirmed that when the lid is closed, no action should be taken.
The battery is fully charged and the laptop runs fine on the battery.
So last night my laptop was running fine on battery power, but then it was running low, so I plugged in the power cord. Nothing happened. Since the adapter at the laptop end was falling apart and duct-taped anyways, I figured it was just conking out, but then I saw the indicator light on the power brick was off.
With some experimentation, I found that if I moved it to a different outlet, the light would come back on, but if I plugged it into my laptop, the light would die, and I would have to again move it to a different outlet (the same one as first would work fine) to get the indicator light back on. It works in other Dell laptops. Other adapters do the exact same thing.
So I'm guessing there's a problem with my laptop wiring that's causing a short or something. (Apologies for my shallow electrical knowledge.) But it was working last night on battery power. Until the battery died completely this morning, it would power up. So it's not an electrical problem that kills the laptop.
I've had my laptop for a little bit under 2 months, so these are the things I have noticed.
Issue number 1: When you plug in the power cord into the computer, the screen freezes on what it is currently on. I noticed this issue because occasionally when I plug in my power cord, and try to use the mousepad to select something, the mouse pointer is gone! I have to unplug-replug the power cable to get the mouse pointer to show again. It seems to have to do with the screen
Issue number 2: when I carry my E7440 around in my bad, or have it shut for long periods of time >3 hours (I just simply close the lid), the computer will SHUT DOWN. The thing will shut down completly, even though I simply closed the lid! At first I thought it was just going into hibernate, so I disabled hibernate in my power settings. But nope, even when the computer is asleep, it will occasionally shut it self down for no reason at all.
Just now, I closed the lid on my laptop, and put in in my bag, then walked to my office about 10 minutes away. When I sat down at my desk and opened my laptop, to my surprise, it had shut down by itself! All of my open windows, browsers, and applications were closed, and upon opening chrome and microsoft word, I was greeted by "your browser did not shut down correctly" and "microsoft word has recovered files". This points to the conclusion that it was not hibernates fault, but instead a issue with the laptop itself shutting down when it is put in sleep. This issue needs to be rectified immediately if it is a widespread issue.
Issue number three: When the computer comes back from hibernate or sleep, the computer is very very sluggish, even when plugged in. It is sluggish forever, OR until the power plan is set from whatever it is to "high performance". upon switching to the previous powerplan from high performance, the swiftness of the system is restored. This indicates to me that the system is throttling itself after it resumes from hibernation, why. This needs to be fixed; many people (myself included) just thought that the system itself was slow and underpowered, not realizing that it was just throttling itself when it emerged from sleep or hibernate.
Have this laptop a couple of months for sons schoolwork. Now it wont stay on unless power cord in. When its on, verything goes fine, it battery icon says its at 98%avaliable (plugged in, not charging). As soon as cord is out, it dies completely no power even when start button pushed.
I got to admit that I got this Laptop for quite a while now but it is still bothering me that it reboots automatically after shutdown when power cord is plugged in. Without the power cord it works as it should.....
I have an Acer Aspire 7740-6656 that shows no signs of life. I have tried removing and replacing the battery as well as trying different locations to plug into power. I have even tried removing battery and power supply and holding start buttom 30 seconds. Except for a green light on the power supply cord, still no signs of life. What if any are my options?
My 11 month old Ideapad failed to boot last night with error 'BL Initialize Library Error 0xc0000029'. Eventually a blue screen appeared saying that multiple start attempts had failed and the system needed repair.
As suggested I tried to use One key recovery but choosing restore to factory settings leads to self same failure.Sadly I have misplaced the recovery disc I created during a house revamp so cannot try that route.
Over the last several weeks, my laptop has been losing power randomly. Sometimes it happens when it is running on battery (and has plenty of power), and sometimes it happens when I go to plug it in. The computer just turns off. How do I resolve this problem?
I can't define fail as stop spinning, but there will be a buzz-saw, grinding like the blades are hitting something, or a sound that resembles an approaching airplane (this WWII diving airplanes) that will continue to grow. It is audible at around 3000 rpm, and when you tilt the laptop at 45 degrees it seems worse. It's not a healthy sound. To hear it the best, run your fans at 6000 rpm and then slow them down to 2000 rpm. At 2000 rpm the fans continue to be inaudible. Unfortunately, it is this audible/inaudible combo that seems to make the problem more annoying b/c I can clearly hear the contrasts. If it was always there, I might be able to tune it out.
This is not an isolated complaint about the classic mbp, but I've had so many of them over the last few years and all of them eventually exhibit this behavior. Every time I have taken it into Apple (about 3 different classic mbps) they have replaced the fan and said it was faulty. Whether they just wanted to make me happy or not is unknown, but a new fan did seem to help...until a few months later.
The model is a HP Pavilion 15-n278sa. My laptop shuts down randomly when it is clearly completely cool, when it has shutdown, the power button will not respond, and the laptop will flash on, and shutdown immediately if it is moved/picked up/tilted, while it is off.The laptop is increasingly getting more unstable and I'm unable to use it...
Scrolling on a media heavy page (like NYT.com) causes stutters with FF3.5RC2 so I gave Safari a try. Fast? Yes. No scrolling problems and loads faster. However I get beachballed randomly. Was just browsing Headfi.org and it died twice and have to force quit.
I have a Macbook Pro (17" Penryn model just before the unibody one) and it's been working great so far until recently...
Lately it's been randomly going into sleep mode and waking up just as randomly as if nothing happened. Someone told me its a RAM issue, but i'm sure it cant be that since that will usually shut the mac down instead of putting it on standby.
Itunes randomly closes when opened. Virus scan came back negative and all of the file seems to be standard. version number 9.1.1 (12) of itunes and OS X 10.4.11. Anyone have any idea what the problem could be? Also updated Java, but it did nothing.
I have recently noted that, sometimes (randomly and rarely for the time being), the pointer of my bluetooth MM (Mighty Mouse) moves farther than what I was expecting it to move. This happened probably in concomitance with the opening of some application (Iphoto once). In other words, it appeared to me that the pointer accelerated more than what I demanded it to move with the displacement of the mouse. It was not really a uncontrolled jump (as it sometimes happens with optical mice) but like a transitory but self-contained loss of pointer control.
I believe that a similar event occurred also once with the trackpad pointer when I went to the bottom of the screen to make dock appear in concomitance with a skype call launch....the pointer seemed to move fast to the right although I am quite sure it was not my finger to command this motion on the pad.
I have tried (with respect to MM) to delete and recreate the bluetooth .plist but it did not prevent from having this occurrence (note also that the batteries are OK). I have read in some other forum, here in this site, that this might be due to OSX pointer acceleration (not perfect) management.
I'm having some issues with my MacBook's USB hub. I have the macbook from 2007 I believe that has 2.0GHz and 1GB of RAM. WHenever I connect my iPhone to the USB port to sync, it pops up with this dialog box that says that my iPhone is drawing too much power and thus the USB hub will be deactivated.
