Notebook display brightness low when plugging out power cable?

Q: Notebook display brightness low when plugging out power cable?

As long as the power cable is plugged in in my notebook the brightness of my display is fine.

But when I plug it out and use the battery the brightness becomes suddenly darker.

Why?

How can I prevent this switch-to-dark-screen?

I found no corresponding option in the power plans

Preferred Solution: Notebook display brightness low when plugging out power cable?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Notebook display brightness low when plugging out power cable?

Try going to the Power options and then click Change plan settings for your power plan then in the next window under battery at the bottom is a adjustment for brightness. Be sure to save changes one done.

Hi Experts, I have a serious problem using my W520 since a few month. When plugging in or unpluggingthe power cable the system directly jumps into Blue Screen (BSOD). I used a small tool to extract the basic dump message: RESOURCE_NOW_OWNED I installed the newest versions of LENOVO Solution Center, LENOVO Energy Management, ...I did an BIOS update longer ago, but I'm not sure, if there was a time-based relation to my problems. The BSOD occurs when: * Laptop started with power cable => Power unplugged* Laptop started without power cable => Power plugged* Laptop in sleep mode => Power plugged and Laptop started again lifting screen* Bring Laptop in sleep mode => Power plugged Does anybode had this problem. Before every meeting now I have to shutdown and restartthe engine... I'm not sure, if the Windows repair CD could detect and repair such a problem.Thanks in advanceKlaus Wegener

I have a HP Pavillion n5350 notebook. When the computer is on you can hear it running, but can't see anything on the screen. I took off the keyboard and found that a little black 5 hole cable that connects from the base to the screen was broke. I have tried with no success getting a part number from HP, and cant find anywhere to buy such a cable. Are these standard cables, are there other resources outside HP to find them?

Hello everyone,
I'd like to know how (if possible) to make it so that my laptop does not automatically change screen brightness when plugging in or unplugging.

You see, there is a brightness setting that is saved for plugged in and unplugged, and when you change between plugged in and unplugged it reverts the screen brightness to that saved level.

For example if you have it unplugged and you set the screen brightness to 100% then plug it in, it saves the unplugged screen brightness to 100%. Now when you're plugged in you change it to minimal brightness. Later when you unplug and leave the screen brightness will revert back to 100%.

I'd like to disable this automatic screen brightness change.
Thanks for reading.

By "plugs in cable" are you saying he is trying to connect to a broadband modem, router, or ?

Is he rebooting the modem or router and then booting his computer?

I'm having a tough time diagnosing an issue a colleague of mine is having. Basically the problem is that whenever this user plugs in a LAN cable his computer would blue screen with the error 0x40000080. After analyzing the crash dump all signs pointed to "e1e5132.sys" driver for Intel® PRO/1000 Adapter NDIS 5.1 deserialized driver. A quick google search revealed a lot of other systems experiencing the same problems so we decided to install the latest drivers from both Lenovo and Intel as the system was previously using Factory Image software. The updates had no bearing on the blue screens as it continued to occur so we tried to re-install the operating system "Windows XP Pro" and saw the same problem creep up. This machine is a Lenovo T-61 so we contacted Lenovo and they replaced the system board citing bad hardware. The next day the same thing happened, in fact it happened to 3 machines within the same department who were all purchased in the same bulk to the best of my knowledge. This user was so frustrated that we switched him out with a brand spanking new Lenovo T-61 right out of the box. The only remains from his old systems were Documents copied over and E-mail .pst files. About a day later "Boom" blue screen again, same culprit according to the Minidump. I want to think there is some files on the system that possibly got copied over that were corrupt but frankly I'm running out of options on this one.I would appreciated some assistance... Read more

The title is somewhat misleading. This event happens maybe once every 20 plug-in attemps and only when I'm slightly up or down from a straight push in.
The device doesn't matter.
The port in question is one of four on the front panel of the case. The rebooting only happens with one port. Never had a problem with the other three.
I haven't pulled the front of the case because it happens so infrequently.
However, I would like some suggestions on the possible cause.

A:System Reboots When Plugging In A USB Cable

As the doctor says, if it hurts don't do it. It sounds like a bad port. Stop using it.
Antec sells the replaceable front port assemblies. Check their website and see if they have one to fit your model of case. They range in price from about $6-$12. It's not likely you'll be able to repair the port.

Hi

I have this weird issue where my notebook starts to stutter after coming out of hibernate whenever the power is plugged in. The mouse doesn't move, the audio goes out, videos stop, and sometimes I get a black screen that disappears in ten seconds. Sometimes after the black screen I get a message saying my video driver recovered. I am running a nVidia 8600M GT with up-to-date drivers. The problems usually resolve if I restart but it's really irritating that I can't get out of hibernate without this stuttering. Switching back to Vista also fixes it. I've tried reinstalling drivers and reformatting with a clean install of Windows 7 neither of which helped. I didn't have this problem with Vista although I had another power issue in Vista (which I still have with 7) where if I put my computer into hibernate with the power plugged in, the computer wouldn't start again until I unplug it and take out the battery.

Would be great if someone could give me an idea of what's going on. Thanks!

So tonight I shut down my computer and unplugged the VGA cable from my graphics card and tried to plug it into the VGA input on my motherboard. The reason for this was because I tried switched from dedicated graphics to integrated graphics (Long story). When it was plugged into the motherboard I tried switching my computer on and my monitor came up with 'no signal' and the light stayed orange. So I tried to plug The VGA cable back into my graphics card then I still got no signal!

II've tried everything from re-seating the graphics card and RAM to trying different monitors and cables. It simply isn't working and all I did was unplug the VGA cable from my graphics card into my motherboard VGA input. I can't post any detailed system info as I am writing this on my iPod (very time consuming!) as I can't even do anything on my computer. But my monitor was displaying everything perfectly fine before I unplugged my VGA cable (when my computer was shut down) I don't see what's causing this.

Any help will be greatly appreciated.

Hi all,

I'm at a dorm room with cable internet. It usually works fine, but now if I unplug it, then plug it back, the computer doesn't connect to the internet anymore. Sometimes it says it's acquiring network address, but that doesn't change. The computer connects to the internet fine if I turned on the computer with the cable already plugged in.

Another computer doesn't have this problem with the same cable, always able to connect after being unplugged/plugged. Both computers are on Win XP.

I suspect the Windows firewall has something to do with it, if only because it is turned on the the problematic computer, and not on the other one. I couldn't turn it off, however, because it doesn't let me open up Windows Firewall Settings, giving me the message that the "associated service is not running" and whether or not I could like to start it. If I click "Yes", it simply says it "cannot open Windows Firewall/Internet Connection Sharing service".

Please let me know what the problem might be and what i can try to get it working again. I hope I haven't given too much useless information.. haha. Thanks!

Ok, I've already ran all the things to not be infected with a virus. What I did in order, removed the drive scanned with nod32, reinserted the drive, ran in safemode networking: spybot, malwarebytes, removed bad files, ran smitfraudfix, then combofix, unchecked things from msconfig, used hijackthis to remove bad things. Rebooted to regular windows, and cant get on the net. The system still responds but its almost like its having issues getting an ip or something. I also tried winsock fix, but it hangs also. Ive had this problem on two seperate computers. What I believe it to be is some registry problem or permission change by the previous viruses i removed. Please dont give me the usual virus scans etc routine. I've been doing this awhile I know how to get rid of viruses. This is separate issue, please help or point me in the right direction. I also had an issue installing avg with the error code 0x80070005, but i solved this by deleting the two DENYs in permissions. Do you think this is a similar issue but a different permission?

I have a desktop with a 25 pin cable running to my printer, and want to print from my Dell D400 laptop to the same printer. The D400 does not have a 25 pin socket so I bought a USB to Parallel Printer DB25 Cable. But I can't get anything to print from the D400. I've put the original printer cable + new adapter cable into a USB port on the D400 but cannot get a signal of any sort to the printer.

I guess this is to do with selecting the right port; through Control Panel > Printers & Faxes I have set this as an HP Laserjet 6P printer. The port options are LPT ports, COM ports, USB virtual port, or Microsoft Document Imaging Writer Port. None seem to work for this.

With the desktop, when I plug the new adapter into a USB and leave it on LPT1 it prints fine, so why am I not getting a whisper from the laptop?

Greetings everyone,
Im not too tech savvy so I will try and explain exactly happened and hopefully get some assistance. I have an HP G42 AMD Turion II Dual Core Notebook that I am using for school (had the laptop for a year now, Windows 7 installed). I use it for watching movies (using GOP player), listening to music (itunes), completing term papers and attending online courses. I recently purchased an HDMI cable to watch movies from my laptop to my tv (I have an old Hitachi CRT 1080p w/HDMI compatibility), and when I plugged the cable in my laptop screen turned black for a brief moment, resumed normal and then completely froze. The only thing I was able to do was power it off and attempt to restart. I tried to restart the laptop and was barely able to type in my password as the welcome screen before it froze again. I can run windows in safe mode (both network and cmd prompt) but I cant run in normal. If more information is needed to troubleshoot I will be more than happy to provide. Thank you for your help!!!!

In 1998 I had house built that included a Lucent Homestar Wiring System ( Series SC200).
Up until know I have provided a Wireless network throughout the 3level house with some pretty good success. I thought I would take advantiage of the Homestar features which were suppose to allow me to use a wired Network through the house.

So i Bought a Linksys Cable Router and a Linksys Switch. I moved the Cable Mdem to the Basement where the HomestarBox is located. Hooked up theHomestar to the cable modem pluggd into to the router. Hooked up the router into the switch . From the swicth plugged into the Homestar Panel. (BTW Had my laptop hooked into the same switch using cat5 cable and I was able to surf internet)
The phonejack are dual mode allowing me to plug in a cat5 cable or a rj11.

Questions:

Does anyone have any experience with Homestar?
Am I missing something in my Setup or my Logic?

As I said in my profile I know enough to be dangerous. I have built my own computers and setup and troubleshooted wireless networks, Also do room to room sharing of 2 tivos over a wireless g network.

Any help or suggestion would be appreciated.

Whenever I plug in any USB device, the monitor will go blank, but the case fans and lights will continue operating. The computer remains like this until I hold down the power button to turn it off and then restart it. It will restart fine. In addition to the monitor going blank, all power is turned off from USB devices (e.g. optical mouse light turns off).

This occurs probably about 25% of the time I plug a USB device in (sometimes nothing happens, as should be).

It does not mater which port I use. It's happened with rear ports, a hub wired to a rear port, front case ports (plugged into motherboard USB pins), or a PCI USB hub.

I've looked extensively for solutions and can't find any. I checked my motherboard multiple times for swollen capacitors and have not found any.

Today (and never before) when I plugged a mouse in, the same issue occurred, but the monitor turned back on about two seconds later, and a pop-up notified me of drivers successfully being installed. (I didn't notice whether USB power was cut) This makes me think that the computer is adjusting the display (as it does when a program requests administrative permission and the screen sometimes goes blank) but for some reason does not come back from it. There really is no indication that Windows stops. I never get a BSOD.

Operating System: Windows 7 64-bit, regularly updated
Display Adapter: Nvidia GeForce 9600 GSO (756MB)

Let me know if you have any ideas. Thanks a lot.

A:Plugging in USB device causes display to go blank

I'm not sure whether this is the correct answer, but you may need to re-install your chipset drivers.

If it is a self-built computer you should be able to get them from the motherboard manufacturer.

If it is a computer bought from a manufacturer then you'll need to go to their driver support site.

Hello all,

I built an Athon 64 3000+ about 2 1/2 years ago, and had no problems; then one day in the middle of an e-mail it up and shuts off on me, refusing to turn back on. I've detached every piece of hardware from the motherboard, including the CPU, with no effect.

With just the 20-pin power supply connector, the fans run, there is power to the motherboard, and the motherboard lights inform me that the CPU is not posting (as one would expect it not to with no power and now no chip). However, the minute I plug the extra 4 pin 12V supply in to the motherboard, the whole thing shuts off. The 4 pin connector reads 12V when the 20 pin connector is plugged in.

Any ideas? The MB is an MSI K8T Neo. I didn't jostle it before turning off, I don't think, and a 300W power supply I have leads to the same effect: the fans run with the 20-pin connector in, but as soon as the new PS's 4-pin 12-V supply gets plugged in, everything shuts down (no fans, no MB lights).

Thanks in advance for any help!
 

A:Plugging in 4-pin 12V supply causes power to shut off

At the least you must try another power supply. It could be any rail, or a short, that is causing it.
And if it's not that, I would suspect the CPU or motherboard died.

Two issues I've had since I got this thing years ago. To repeat an earlier post that was never sufficiently resolved:
I noticed that half the time, when i plug in my adapter to charge my laptop while I'm using it, it goes to sleep. I know it's asleep because (a) the fan stops running and (b) it's woken up quickly using typical methods to wake a computer. Anyone got a clue about how to prevent it from auto-sleeping? Thanks!
Add to that: the video freezes up when watching various videos - youtube, dvd's, VLC player, anything where the screen is showing a video.
Both are a constant nuisance and the recommendations of updating the bios, all drivers and such are a waste of time. On the power issue, should I replace a part on the motherboard or add something?
I'd like an answer. If I have to "replace the motherboard" please share a model that will fit and work properly but will NOT be a 5558 because I don't want to have to go through that and sill have the same issues. At this point wanting to brick it and get an HP laptop.

Acer 7740g, Windows 7 HE.
I have this annoying problem that when my AC power is plugged or unplugged it makes a beep.
Muting the sound completely helps, but that's sometimes not an option.

I tried the following and no luck:

Editing a registry entry HKEY_CURRENT_USER\Control Panel\Sound\Beep and changed it to "No".
Uninstalling the Beep device from my device manager.
Turning off my pc speaker, unfortunately, I didn't find where I can disable it.

My sound card drivers are: Realtek 6.0.1.5969

Anyone has another idea?

Thanks.

Hello. I have a very frustrating and unusual problem. When I connect my power cord to my laptop, I lose connection with the network and internet. Zap. Gone. If I unplug my power cord, TADA, it comes back! Oddly enough, my wireless network card is not affected by this madness - only my wired LAN card. Any CLUE as to what could be causing this unusual problem?

My gratitude,

Jason

We have the same problem, and we noticed if we press down with our fingers on the top and back of the laptop right near the power cord jack the problem resolves. What problem would that represent?

I recently upgraded from Windows 8 to Windows 10. Afterwhich, everytime I plug the power cord, my screen goes black but when I remove it, the screen lights up again. Already checked power settings but I'm pretty sure its not the issue. Please help.

Ok so here's the deal. I just plugged my PSP into my desktop and suddenly all of my peripherals stopped working. I took the psp out out and restarted my machine, but it would not power back on.

Heres what i've done so far:

-unplugged everything; reset the bios battery;turned the psu on and off

-unplugged /replugged in all the important power plugs for the machine

-reset the 6-way that i plug my pc into

I have attached this psp to this machine before with no problems. After doing the steps above, I am ****ing clueless as to what could be going on. also, my mobo power light is green(implying that power is being run to the machine)

any ideas fellas?

I'm having a problem with my laptop (HP 6530b) locking up when I plug in the power cord.  This happens when I'm actively using the computer on battery and then plug in the power cord.  When I do that, I get two beeps and the computer freezes. Nothing else is plugged into the machine at the time.  Any thoughts on what may be causing this?  I'm also experiencing occasional BIOS errors (501) which may or may not be related.

I have a three port SATA controller PCI card, into which I successfully ran two 500GB SATA HDDs. One of them had the old-style 4-pin power socket (PATA IDE drives), while the other needed an adapter cause it was a SATA power connector only.

Anyway, all was fine until I purchased a third SATA drive and plugged it into the remaining slot, situated on the out-facing metal plate of the controller card. This one also needed a power adapter for my old-style PSU. The new drive worked fine, but the second of the two original drives fails to load.

First of all, am I right in guessing that it's not a power issue? The reason I think this is because in the past when I've plugged an unpowered drive into the SATA controller, it renders the SATA controller useless, and none of the SATA drives appear in My Computer. So, because I can get two out of the three drives to work simultaneously, am I right in thinking that it's not the power?

Is there some sort of SATA BIOS that I need to tap into to enable something? How is this done?

Any ideas?
 

A:Solved: SATA HDD #2 fails to power up after plugging in HDD #3

Should I just accept that this is infact only 2 port, and that the 2nd and 3rd slot are shared between one inward facing slot and one facing out of the computer case? Or is there some way to enable the 3rd port?

This is so odd. I'm running Windows XP SP2 on Dual core INtel with 1 gb memory.

I've installed a front USB panel that has 4 ports in front and 2 more on the PCI card which it's attached to. (added on peripheral).

I can deal with the "this device can run faster if plugged into a 2.0 device" but what is really frustrating is that if I plug in 2 or more USB devices. At least one of them won't work.

This computer is in my family room and wirelessy networked to my other computer in another room. I use a Motorola USB device to connect for the purpose of printing stuff off the printer in the other room.

If I have too many USB devices plugged in - there doesn't seem to be enough power to allow the wireless connection - resulting in not being able to print.

This isn't the only issue. I have some software that requires the USB "key" in order to work. If I need to use that software using the "key" and then I need to print something from that particular software to the remote printer - I have to save it to my desktop firsti - then disconnect the "key" and then I can print.

Do I need a bigger PS? I have a 500W now. I thought that would be big enough. Perhaps the USB issue isn't related to that at all? Is there some way to regulate how much power is assigned to USB devices?

Since my computer is in a desk against a wall - it's very difficult to plug and unplug stuff into the rear slots. Hence the install... Read more
