Dell :: Power Cord Light Turns Off When Plugged Into Laptop Short Circuit?
May 29, 2010
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 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?
I have a dell inspiron 15r 5521 laptop. Yesterday when I tried to turn it on it won't boot, even the POST or the BIOS won't show up. I removed the battery and power supply and press down the power button for a long time and repeated it a lot of times too but no luck. I removed the HDD, RAMs and the CMOS battery and kept it that way for 5 mins and put them back in but it was still the same. I noticed that whenever I enter the ac adaptor into the laptop the fan moves for like 100millisecond and the light on the caps lock button lights up for the same amount of time then it all goes silent. Same happens when I press the power button with only the battery inserted.
All what happens when I try to turn it on is that the power indicator light on the laptop turns on(white color, which is the normal color for this laptop), and that's it. The light don't blink or anything at all. No beep sound. The fan, HDD everything remains silent. Only that light stays on until I unplug it from ac and remove the battery. Pressing down the power button doesn't turn it off either. No other indicator light such as the wifi's, hdd's, battery's light doesn't turn on.
.After I push power button, one of 3 lock lights, the A lock flashes blue, and a steady blue power light occurs to right of keboard, for about 5-7 seconds, then turns off after a soft high pitched beep.. The computer did get hot before this occurred. Tried getting new power cord because old one was not correct one. Tried booting up with and without battery & did not work. Screen never comes up.
I have a Dell E4310, about 2 years old. When I connect the charger just to a power socket the green light on the charger comes on but when I plug the other end into the laptop the green light on the charger goes off, I have taken the battery off the laptop and it still does the same thing, and in both cases the laptop will not power up and no light appears on it.
Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.
Round 1 was the GPU and thanks to that ordeal I made my share of posts in the venerable "Vertical Lines on Reboot & Crash & Vertical Lines" thread.
To insure I wouldn't have to go through a mobo swap again, I also did the infamous Cu Mod - which, btw, worked flawlessly and I still support the concept, regardless of which revision nVidia GPU you may have.
So talk about my astonishment when my 1330 just powered off instantly last night while I was doing some 3D work (*and* charging the battery...). At first I thought it was an OS glitch but after noting that I couldn't power the 1330 back on, I realized I was dealing with another issue.
Round 2: Symptom, diagnosis & prognosis:
>1330 will not power on and the external PS's blue LED is not lit.
>Connecting the 1330's PS (adapter) with the 1330 causes the PS to immediately switch off (fail-safe circuit).
This is easy to determine because the infamous blue LED goes out and stays out until you unplug and replug the adapter to the AC outlet (mains). Reconnecting the 1330 with the PS causes the PS to once again switch off. And so on.
>Hence, my second Mobo replacement is on order... sigh.
There's the slight chance that it's only the so-called "charger Board" which is actually connected to the mobo (see my pics - link in my sig. below) but the last time they replaced my mobo, they replaced the charger board along with it.
I own a Acer Aspire 8930g which I bought at the end of November 08.
Ive been having power problems, Id be playing a game or just browsing the web, and the machine just switches off. Upon booting up again and logging into windows I notice the battery is completely flat, and is charging at 1%
The laptop is ALWAYS plugged in.
It seems to run down the battery if the computer is put into sleep mode, even though the power is plugged in, and also, I think, cant be 100% but seems to drain the battery even when fully shut down with the power plugged in.
Strrange problems and is really annoying as you would imagine if your in the middle of a good game or halfway through a good movie.
This is a late 2008 build Dell Inspiron 1545, sold retail in December 2010.
Pentium dual core T4500, 2.3 GHz
Has been in irregular use as a spare machine, mains adapter only, battery removed. My house was struck by lightning over a year ago and adapter damaged. Replaced adapter and no further issue until now.
Laptop would not power up, no light. Tested adapter and tried another 2 adapters - still no power up. Replaced original adapter and plugged in depleted battery - powered up but had to press F1. Powered up with no issue with good battery. Once powered up the laptop seems to be charging battery OK. Guessed this was a power board issue but no change when replacement fitted.
I have a Dell Inspirion 1526 that when I turn on the laptop, the blue power light comes on and the lights all come on but the screen is black. I here my laptop running but it looks like my screen just stopped working. I wasnt sure what it was so I bought a new battery to see if that was the problem and the screen still does not come on. I had this laptop for about 3 years and thought it was the battery or charger and its not.
I have a HP Pavilion M6-1045DX laptop and I recently tried to plug it into a display through the Analog RGB and I saw a spark and the laptop shut off. During that time I ran the laptop straight from the AC adapter without a battery because I don't really use it.So the laptop shut off and I tried turning it back on and nothing happened. The charge indicator light turned off even though it was still plugged in. I thought maybe the power adapter stopped working or something but I tested it with a voltmeter and there was still power in it.
So I decided to put the battery in and the laptop was able to turn on, but after a while, this one area that i never felt heat there before was really hot and later smelled like something was burning.But anyway, when it booted up, the screen resolution was really low and was on maximum brightness. When the laptop finished booting, it randomly started installing drivers (such as the WLAN and intel rapid storage) and yeah. Sound doesn't work either. I tried to plug the laptop back in and the battery won't charge.I turned it off and took out the battery and tried running it off from the AC adapter only but the power light was blinking constantly and when I press it, the WiFi button light (F12) turned on for a second and back off. I also hear this high frequency noise that I never heard before somewhere in the laptop.
My laptop wont turn on, whenever I press the power button all the lights light up for about a second, I here the fans turn on and then it shuts off. When I plug the charger in the the charger light blinks, but thats it.
My battery on my acer draws power at times when my laptop is plugged in it will work ok then the on and off button will start to blink It will go into hibernation when plugged in when the battery gets to low....
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 did customize the bios, but Wake on Ac is not enabled.
What is occurring is if we leave the laptop not plugged into an AC adapter overnight, the next time the laptop is connected to the ac adapter it will turn itself on. This occurs even with the lid closed.
I suspect the problem is coming from the Auto on Time in the bios. We have the Auto on time set to 12:01am (local). My suspicion is that if the auto on timer is missed, it is turned on at the next possible moment.
Is there a way to set the machine not to auto on if it misses the auto on time?
We are using the A09 bios version, and below is the ini file taken of bios settings from the cctk. (minus the service tag.)
I have a Latitude E6510 that will not start. When pressing the power button, the power light goes on for about 5 seconds and then turns off. I also notice the battery light flashes a few times when re-connecting the AC adapter.
Removed the battery, held in the power button 30 seconds, but still not working.
We have had this laptop about 6 months. About a month ago, it exhibited this problem. After talking to Dell Support, they recommended a system board replacement. The laptop was sent in and the board was replaced. When I got it back and tried to start it for the first time, it did the same thing. I then pressed the Latitude "ON" button, and the laptop started.
Now it is doing the same thing, and I find it hard to believe that another system board is bad. I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode. Or maybe it is just trying to get into "ON" mode.
I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem. Again--I find it hard to believe a second system board could be bad.
I have a Dell Inspiron 1520 and my friend has a Latitude D820.
Tonight she accidentally plugged my power adapter into her laptop. A few hours later, she noticed that her laptop indicated that it wasn't plugged in, and that's when we realized that she had accidentally used my adapter instead of hers.
Now my adapter doesn't work at all. We've tried the adapter with both our laptops with different outlets with the same problem, so we know it's the adapter. The green light also doesn't come on when it's plugged in anymore.
Did plugging my adapter into her laptop somehow screw up my adapter, or could this just be a coincidence? Is there any way to fix the adapter or at least figure out what the problem is? And if I have to purchase a new adapter, do the universal ones they sell at retail electronics stores work OK? I would order one from Dell but I'm working on a project now and I don't have time to wait for it to ship.
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.
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.
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 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?
