Dell Studio 1749 :: Power Adapter Is Plugged Into power Board Along Side Of Laptop
Jan 27, 2013
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.
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.
Last Friday i received my new Studio 1749 with i3. As told by the documentation I put in the battery, put the power cable in the ac-adapter, pluged the AC-cable into the laptop and then pluged the ac-adapter into the wall outlet. I booted the laptop and once I was on the windows desktop had a look at the battery symbol. It showed that the laptop was connected to external power and that the battery was being charged.
I wen't away from the laptop to let it charge the battery for 12 hours as told by the documentation. After two hours i came back to have a look at the laptop and it was off. Curious I turned it on again. After booting up it showed the battery at 60% and the laptop running from battery. Yet the ac-adapter was connected to the laptop. I hadn't changed anything. I pluged the adapter cable in and out, but it wouldn't recognize that the was external power available. Turning the laptop off an on again didn't work either.
Now I feared for the battery. My guess is that at one point it started to run on battery power even though it was not charged for 12 hours. Then when the battery was depleted the laptop shut down. This might have permanently damaged the battery!
I guess as soon as the laptop was off the ac-adapter charged the battery again, and when I came in it was just at 60%.
So I turned it off removed the ac-adapter, removed the battery, put the battery back into the laptop pluged the ac-adapter back in and booted up again. Now it showed it was running from external power again. All fine. It charged the battery as well. Actually it charged the battery up to 99% and then out of nowhere the battery symbol changed and it was running from battery AGAIN! Even though it was still connected to the ac-adapter. This happens all the time. It is reproducable.
So I thought something might be wrong with the ac-adapter.
I powered down the laptop and removed the battery. Now with only the ac-adapter connected ,I tried to start the laptop. The control lights above the keyboard came on for 2 or 3 seconds and then the laptop turned off again. Trying to hit the power button again after that didn't give another reaction.
Conclusion: The laptop won't run just on external power with no battery in the battery bay.
I put in the battery again. AC-adapter still connected. Hit power. Laptop starts to boot. Then while booting I removed the battery. Laptop keeps on booting - finishes booting - runs nice and well at full speed not missing the battery - FOREVER.
So it won't boot with the battery removed, but it will run without it flawlessly??? Strange isn't it?
Next test: I put in the battery again while the laptop is running from mains. And now it charges the battery again until the point... you already know... it "forgets" that it is connected to the ac-adapter and starts running on battery power. So now I boldly removed the battery while the laptop was running. After all it was still connected to mains/ac-power.
My daughter's 1749 laptop shut itself off and now when you plugin the power adapter, the light over the plug on the laptop blinks three times. It will not power on at all.
I have replaced the power jack in the laptop as well as the cpu and tried different known-good ram but nothing makes any difference. What does the light over the power jack blinking three times indicate?
I bought one Alienware M14 x last month. However, I found it won't boot when the power adapter is plugged in. If I unplugged the power cord, then press the power button, it will start normally.
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.
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.
how the power adapter of the Studio XPS 13 looks like, because the size of the power brick is essential to me. Although you can buy a separate one but that would be a waste of money.
So my question is, what's the difference between the 65W power adapter and the 95W power adapter? This is because choosing the Geforce 9500GE online would change the power adapter from 65W to 95W.
Why is this anyway? Isn't the 9500GE suppose to save more battery than the stock 9400GS?
I have just installed an i7 2670Qm on my T420 today.The machine will crash pretty soon after booting up, with the screen having colorful vertical and horizontal lines before it restarts itself and give the memory error beeping pattern (1 beep-pause-3 beeps-3 beeps-pause-1 beep).So then I took out one RAM from the bottom, and the machine appears to work normally again, more or less.
In the OS (Win7 64), The power manager alerts me that the 65w AC adapter is giving not enough power, so the laptop is running on battery. I thought I just need a 90W AC brick so the laptop will work as it should, so I am arranging a 90w one to come in later. But on a second thought, if the battery cannot start the laptop with 8GB of RAM properly.
Is it the CPU or RAM or Mobo or something else? Where should I look?The machine works fine with the previous CPU i3-2310m and 8GB of RAM.The RAM modules I have are 2 x 4GB Samsung 2Rx8 PC3-12800S-11-11-F3.The BIOS version is updated to the latest 1.46.
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....
After replacing the fan, I have a power up issue with the laptop. Basically, the laptop will only power on with the power cable disconnected at the motherboard. It was by mistake that after the fan was replaced and everything was put back together, that I noticed that the battery was not charging.
I then reopened the machine and reconnected the power cable to the motherboard and nothing - no power.
When plugging in the power source with the battery in place, the LED adjacent to the power socket lights up WHITE then stays ORANGE and will not power up. No other lights, no fan noise, nothing.
If I remove the battery, the LED adjacent to the power socket lights up WHITE and stays white however will not power up either. Same agin, no other LEDs, not fan noise, nothing.
I have now opened the machine back up and disconnected the power from the motherboard. Put it all back together and the laptop powers up as normal with the battery and it works fine. (Well until the battery runs out anyway).
i was watching family guy in the kitchen today and when i plugged the laptop back into the AC adapter it just shut down,
i attempted to restart but it will not boot up at all ive attempted to take the battery out and then try with that however nothing happens at all any ideas on what ive done and how to fix it?
I returned from windows 8 to windows 7 64 on my Dell Studio 1749 because i had a Hibernation problem.
Now the problem is not solved, i've the same in my windows 7 64 (when the laptop hibernate, it freeze). I think it is a bios error, and i want Reset it, but, if i try to reinstall the last bios, installation program does not work and report: "the last bios is already installed).
I own an Inspiron 1545 and would like to set-up two profiles, one for use when on battery and one for use when plugged in. Basically,
I want my laptop to run at maximum performance/brighter screen when plugged into the wall and have it run in a power-saving mode when running off the battery.
The Windows7 power options don't seem to be able to differentiate between plugged-in and battery operation. Is there perhaps a program which I can install to do this or is it just not possible??
Working on a dell Inspiron b130 laptop. The power is plugged in, and battery is in. The power will not turn on at all, no fan or CPU. The main power light comes on when button is pressed for a moment then goes off. The battery light flashes slowly. The power cord adapter has a light on it and that says its working. I have tried taking the battery out and that does nothing.
I had assumed since its an older laptop that maybe the power was so drained that it needed it to be charged a little to have enough power to turn on. But it's been awhile an nothing yet. Is it trashed? We do have another hard drive around to try would that matter at all?
dell xps m1210-worked fine forever-few weeks ago intermittent failure to show charging when plugged in-jiggled-twisted-would charge. last week same issue-no amount of jiggling would produce charge indicator. took to fairly well rated shop after research re installation of new ac jack-after done no difference. they find power enters at jack and then they lose it on MB somewhere they cant seem to reach to test.
I've got a new power adapter which is 65w. When I plugged it a warning message popped up saying Im using a 65w adapter and my system will operate slower and that my battery will take longer to charge.
The part with the battery taking longer to charge I get but does my system will really work slower ?
I really would like to get two of these, since they are less than 1/3 of the price of the adapters I can get in Norway, but I'm a bit suspicious.
The original adapter for my Precision M6500 is 210 watts (which is totally crazy, but I guess the Fire GL card eats most of it), and this is rated at 90w. But will it even work? Here's the eBay auction, it's in Great Britain:
I just received my e6400, and it is now charging the battery. The ac power adapter is very very hot, is that normal? Should I ask them to change one for me?
