Dell :: Running The Laptop Always On AC Power
May 28, 2009
I own a S1555 from Dell. Currently i am using the laptop on AC power which is supplied by an UPS. I have removed the battery from the laptop. I have connected the laptop to the UPS because even in the case of power failure, the working will be uninterrupted.
Now my query is, will it harm the laptop in the long term? I read about the laptop overheating in other forums, but strangely mine does not overheat, although i keep mine connected to AC power 24x7. I do all sorts of stuffs like gaming (the most recent one was GTA 4) and word processing on the laptop.

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 Studio 1737 running Windows Vista Home Service Pack 2. I'm running the latest BIOS and all of my drivers are up to date.
When the AC adapter is unplugged and I'm running on battery power the whole system lags. It also turns of when unplugged without warning after about 15 minutes.
Also, I get these error messages in my event viewer a couple of times an hour:
Log Name: System
Source: ACPI
Event ID: 13
: The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.

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 bought a new Dell Inspiron 15 7000 core i7 with touch display about a week ago. I've noticed that on occasion, especially when running on battery power, the screen flickers slightly.

I have encountered a problem with my laptop - a Dell XPS 15. When the computer turns on, or I insert the charger, the following error message appears:"The AC power adapter type cannot be determined. Your system will operate slower and battery will not charge. This problem might be solved by: Ensure the plug is inserted completely for best system operation. Connect a Dell 130W AC Adapter or higher." I first encountered this problem a few months ago but on occasion, I have managed to get it working by taking the charger in and out a few times.
Though over the last couple of days, it won't charge at all. I have tried using another charger, which yielded the same results; though it was not the exact same charger and actually has a lesser power output. I also checked the bios during start-up, and next to AC Adapter Type was 'Unknown'. Though the charger can power on the laptop without the battery inserted. Just yesterday, my computer also started operating a lot slower, at an almost unusable speed and I think this might be related.

HP Envy 15" TouchSmart laptop running Windows 8.1. This is a problem that just started today, it has to do with the screen and fans where the Power LED lights up white, just as when the laptop is running properly.
My laptop was opened and turned on, functioning properly. I had NetBeans IDE running since I wanted to work on the second part of my current CS 137 (Programming Principles) assignment. Because it was almost time for my lecture, I closed the laptop by simply moving the screen back down onto the keyboard, where it goes into sleep mode. (Anytime I flip up the screen, the laptop is supposed to come back on, and the login sliding screen from Windows 8.1 shows up.)
When I took my seat for the lecture, I wanted to spend a little bit of time to work on my programming assignment. However, upon flipping the screen back up, instead of having the login screen show up, I encountered the problem: the Power LED is showing a white light, but I can't hear the fans running from the vents on the left side of the laptop, and the screen does not turn on. I did try to hold the power button for several seconds, and once at least 10 seconds, except that the Power LED keeps on showing a white light. The light for the Wi-Fi board does not show up.
Whatever it is, I don't want to pull the battery out because I did do that on my last laptop, and it was from there that I couldn't turn the old one back on again. If I pull the battery out from the Envy laptop, it'll short-circuit the connections from the battery to the computer, and thus several components will fry. For now, what I'm doing is leaving the laptop as is to drain the charge on the battery. And then, once I notice that the Power LED does not show a white light anymore, plug the AC adapter, then try turning the laptop back on using the Power Button.

For the past few days, I woke up to my laptop's fan rather loud spinning. I noticed that my computer was constantly at 100% CPU usage even with like literally no processes opened, and it's idling ~50C.
It's to the point where moving my mouse across the screen lags, the pointer jumps from one spot to another.
I'm not really sure what the problem is, I ran AVG with no problem, and I don't remember doing anything to my computer in the past few days that would be considered abnormal...in fact, the only thing I did do was try to use a screensaver for the first time ever, but I turned it off with no difference,

So I know I made another thread about over heating, but it's not drawing that much attention.
A few days ago my Inspiron 1420 was crashing due to overheating (I've had it for a year and a half).
Dell came out, replaced the motherboard, and things were fine until it started overheating AGAIN a few hours after the techie left. Dell came out the next day with a new hard drive, heatsink and fan.

My lenovo z410 runs games (also new "Watch Dogs") realy good only with ac power plugged in.
When I try to play (not only WD also "americas army proving grounds" but its not the point) without ac [lugged in the game is super slow!
Another point:
ac plugged in -> fan works fast.
ac not plugged in -> fan works a lot slower
How can i change settings so i can play without AC plugged in?

I've been trying to get Vista Ultimate to run on my laptop for a while now, and every time I install using a clean installation, it runs painfully slow. If i have more than one window open its not even worth using. So I always run back to XP and I'll be honest in saying that I'm quite bored with it.
how to make it run better with Aero?
My Laptop's Specs Are
Brand: Acer Extensa 4220
CPU: Intel Celeron CPU 560 - 2.13GHz
RAM: 1GB DDR2
Graphics: Moblie Intel GMA X3100

i am using a Hp 2000-2312TU laptop. It is just about 15 months old. I use it with windows 8. my laptop was getting heated up a lot. i used sppedfan to test it. temperatures were showing around 83 degree celsius. I took it to a shop and they said some error with heat sink IC and replaced it. Now the temp is ranging between 65-70 degree celsius. is it okay? HDD temp is ~40 deg celsius. I use my laptop always on bed or lap. is a cooling pad must?
P.S. the reason why i took it for servicng is that it showed thermal shutdown messages everytime i was rebooting it.

I was just checking my wife's older HP Pavilion dv9628nr running Vista Home Premium with 2 HDD's. I didn't even know it had 2 HDD's. I opened the case to make sure.
Below is a screenshot of Disk Management for this system. I have some questions:
1. Why is there an OS partition on each HDD?
2. Are 2 needed and can one be deleted?

I have an HP Pavilion m6 running Windows 7 Home Premium.
My workplace installed a router a few months ago. It's a Cisco E2000. My laptop will not recognize the wireless signal from the router. It recognizes about 10 other wireless signals from other locations outside the office. My phone also recognizes the router and can connect to it no problem. I've installed all the updates for Windows 7 and for the HP laptop. I've also installed the latest driver for the wifi card in the laptop.
Why the laptop does not recognize the wifi?

Recently, my HP Envy M6 has been intermittently losing internet when running on battery - it's always fine when plugged in, however. I've run the wifi manual diagnostics and nothing is detected.
I'm running windows 8.1 and the model number is Model:E0R92EA#ABU

My Aspire V3-771 is a little over a year old now. I don't know much about computers, but i do enjoy several pc games, and watch a lot of streaming videos. when doing so my computer almost always shuts itself off, even while running games that could hardly be called graphic intensive. I'd thought it might be an overheating issue? but i don't think that's the case.
I've also noticed that, within the task manager, the disk will often jump to 100%.
Again, for months after i bought the machine, it worked perfectly fine. many of the programs that it used to run, now cause it to shut down without warning.

I recently formatted my laptop to windows 7 ultimate and since then can not get my function keys to work. I've reinstalled drivers that I thought might work and nothing.
When I could no longer adjust my brightness is when I noticed that my function keys were not working. Is there any other way to adjust the brightness on my laptop besides the function keys? If so I have not figured it out.

I've bought a new laptop 1 week ago, and it's running smooth with 1 exception: Everytime I shut the computer down or save energy, it magically forgets it has fans to cool cpu and graphics card. When i try to run a game it will gradually drop fps until it shuts down from overheating. I tried to fully discharge it and disconnect it from the battery to identify the hardware and then set it to standard in the bios, then it works. But the moment I shut down the computer it is the same thing over again. I don't want to do said process everytime I start my laptop..

I have an Inspiron 7010 which is 2 years old. In control panel devices it tells me to troubleshoot the laptop and cannot rectify problem with Broadcom virtual wireless adaptor. Secondly running the diagnostics say the Read test is not running. These are the only problems but are not affecting the efficiency of the PC. Should I ignore it?

I have an XPS M1530 running Vista Home Premium 64-bit, T-9300 Processor, 6 gig RAM, 320 gig 7200-rpm harddrive. I am using it with the Kensington SD100S Laptop Docking Station (with stand) and a 22" Samsung monitor (monitor as primary display and laptop display as secondary display) and the Dell Bluetooth keyboard and mouse. The Kensignton docking station attaches to the M1530 via USB.
My question is, is it safe for me to detach the docking station when the M1530 is booted up and running? What about detaching the monitor? Except when I have an external USB harddrive turned on, there is not anything in my tray icons to indicate (as far as I can tell) that any hardware needs to be safely removed.
I have a 2nd AC adapter in my den separate from my home office, but I so rarely take the laptop mobile in the house since I power down first. Please let me know whether I am being too cautious, and if it is safe to detach the docking station and monitor while running any precautions that I should take. I do have my XPS backed up via Ghost if a problem should happen.

My Dell Inspiron 5423 laptop does not power on normally; when I press the power button, nothing happens (no lights, no sound). As a result, I have to press the Embedded Controller reset button at the bottom of my laptop for the power button to work. I don't want to have to undergo this procedure every time I turn on my laptop.

I recently got a new battery for my Inspiron 15R, N5010, charged it but didn't use it for a while. When I decided to do some work on it, now the Power botton and Battery light is flashing white. Try the troubleshooting of removing the battery, power cord and hold the power botton down for 10 seconds, it's still flashing. Not sure what to do next.

just got my Refurb Dell XPS studio 16 3 days ago, and there was a weird sparking noise(nothing visible) coming from the brick.
So, I disconnected the adapter and plugged it back in. That reduced the noise, to where I can only hear it if I stick my ear to the brick.
I called Dell Tech support and they said they will send a replacement. So, 2 questions
1) Is it normal to hear that sound if you put your ear next to the adapter(It's like some sparks are going on inside .....

I was thinking of purchasing a Dell XPS 1530 for college. I have everything customized exactly the way I want it but I was wondering if the bluetooth option was absolutely necessary for college campuses? I really do not want bluetooth in my laptop if I do not have to get it as I hear bluetooth drains laptop battery power, but is it required by todays standards?
