HP Pavilion G6-2148TX :: Laptop Will Only Power On With Power Cable Disconnected At Motherboard After Fan Replacement
Oct 21, 2014
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 this inspiron 15r 5521. Its approx 2 year old. There was warning in battery status in the PC checkup. Few days afterwards the laptop did not start up. I searched and did a hard reset..BUT when i shut it down or hibernate . again its like dead and i have to plug in the power cord for 20 min and do a hard reset to turn it on . It also happens that if i shut down while the power cord is plugged and i take it out and again plug it , it stops charging..(again need a hard reset).

I have recently bought a T400. At the moment, it is running on Windows XP, Service Pack 3.
After installation of Windows XP, I have installed all the relevant drivers and no yellow question marks appear in the Device Manager panel. However, during the process of installing these drivers, now whenever I plug in our take out the AC Power Plug, the screen goes blank for about a second and then comes back.
This problem was NOT there immediately after installing Windows XP and Service Pack 3, i.e. before installing the drivers. I think that it is one particular driver which may have caused this.
I have already tried re-installing the Graphic Driver.

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.

Last summer dell replaced my motherboard and since then, my webcamera stopped working. It cannot be found on device manager and the blue light next to it stopped blinking when my system is booting.
Thus, I guess that the technicial forgot to connect the camera cable on my mtherboard. Does anybody know how I can connect it? Owner's manual doesn't mention anything about the camera...
I have tried to install the drivers and the support software but then when I run Dell Webcam Center I get the message "No supported webcamera detected. Please plug in to continue..."

The laptop won't power on. I've tried it with and without the battery. I've tried it with just the power cord. The light near the power cord lights up. When I press the power button it flashes once there and on the CapsLock key, then goes dark. I've tried removing the battery and power cord, holding down the power button for a minute, then plugging in the power cord. Same result.

I just bought my HP Pavilion 360 less than a month ago and it's only been used for schoolwork and research. No virus or threats were detected. It was working fine today until I had to charge it. When it was fully charged, I turned it on and the screen just froze. I tried shutting it down by pressing the power button but it didn't work. Now, the screen's just black but the power button's lit up (meaning it's turned on). What do I do?

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.

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...

My z500 cannot boot up without power cable plugged in. Usually,a few seconds after I saw the lenovo logo,the system will suddenly shut down just like the battery was removed.however,if I connect powercable to the laptop and power on,everything is fine,I can enter windows 8,or ubuntu,after I enter OS,I can disconnect the power cable without any problems.the battery is healthy and can last for more than 2 hours.
So far I tried the following methods:
1.update BIOS
2.update battery firmware
3.reset BIOS
none of them worked for me....

So the power jack on my D520 seems to have broke.. It still works, but the center of the plug is missing, and the cord pulls out very easy... What would i need to do to replace it? Looking at ebay, i can find it for a few $, http://cgi.ebay.com/DC-Power-Jack-De...item45e96642b7
Does this require soldering? Seems like a cheap design or something.

I have been having issues with my battery since a year after purchase. Battery replacement error pops up. The power adapter usually quits lighting up, then it would light up. Today the laptop went dead and the adapter will not light up at all! Is it battery or adapter or both?

After I was done cleaning my vents and fan today, I was greeted with a white screen upon booting up.
Since the screen gets power, and it works when connected to an external monitor, I do believe I have accidentally poked out the cable that connects motherboard to LCD.
And since that's under the not-user-accessible portion of the case, it may take a while for me to get at it.

I have a Dell Latitude D800 that will not power on. When the power button is pushed the green power indicator light comes on, the CDROM spins for a moment, but then nothing happens, there is no BIOS information displayed, no power on self test, no Dell logo. It just sits there with the green power light on.I have tried removing the power & battery then pressing the power button for 10 seconds (actually, I have tried as long as 60 seconds). I have tried to turn on with the power connected but not the battery. I have tried removing the connector cable for the power button and the connector cable for the display and then reseating them.

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.

I enjoy the feature of automatically powering off the optical drive in power manager. My issue is after reformatting my T530 the option is there until I do an update using the Lenovo ThinkVantage System Update. One of the updates seems to remove the feature from the power manager.

I am trying to install a Dell TrueMobile 375 Bluetooth module in my Latitude E6420. I have read the instructions in the E6420 Service Manual but it is not obvious where the other end of the cable on the 375 Bluetooth module plugs into the motherboard. The images provided in the Service Manual are of no luck, as they only show where the module goes, not where the cable on the module plugs into a corresponding socket.

When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?

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.

I have an Aspire 6930 that suddenly died and will not power on. The LED power button was dark and unresponsive. I performed a power reset and the blue light on the power button came back on until I pressed the button to try to restart the laptop. When I did that, the blue LED immediately went dark and stayed that way until I did another power reset. It never gets to the point of anything powering on. Is it a problem with the battery or it the laptop toast?
This is a real bummer since I just replaced the hard drive a few weeks ago and replaced Windows Vista with Linux Mint (which btw is blazing fast compared to Vista).

Product name: HP Pavilion g6
Product number: A3A09EA#ABU
My problem goes as following:One day I realised I cannot use my built in camera anymore. Tried reinstalling original preinstalled Cyberlink Youcam software, but as you can assume if that worked - I wouldn't be here. Then I tried troubleshooting according to HP guide. The problem is there is no category called "Imaging devices" at all.
I can place two bets on what could actually happen:
a) somehow I managed to delete basic HP webcam 101 driver.
The exact name of the device is: USBVID_05C8&PID_021E&MI_00
b) internal camera itself broke down (it's not unplugged cord issue - made sure myself)
I believe I could try installing basic separate driver for the camera, the problem is I cannot find one/cannot find reliable source. Could you send me/upload it for me?
