HP/Compaq :: Fan Won't Turn On When Laptop Is On Battery Power

Oct 19, 2009

I have a HP Compaq 2230S business laptop, but this question could be put to any HP laptop. The fan is constantly running when the laptop is plugged into the power outlet, but as soon as I pull the plug to run on battery power the fan powers down and stops. I re-plug the laptop back in and the fan kicks up again.

This is not good as I almost burned myself when I picked up the laptop after an hour sitting on the table on battery power. The hard drive is right beside the processor, so the laptop gets really hot.

Vista x64 Ultimate is what I'm using at the moment and my power scheme calls for 1% minimum and 100% maximum CPU on battery power.

Dec 20, 2009

My mother was having some trouble with her laptop, and I was wondering if you guys had an idea of what the problem could be. Basically, it won't turn on, even with the battery plugged into the wall. It is completely unresponsive. The last time she used it was last night, and she said that when she was done, she left it on with the screen down and the battery plugged in.

Sony :: Vaio Does Not Turn On Without Battery, Bad Power Supply

May 4, 2010

I have a 12'' sony vaio with a 16V power adapter. My battery is not good anymore, it was not even holding for 20Min, but my problem now is that the computer does not turn on without the battery at all. I have to leave it charging for hours, then it will go on, but in the middle of the windows loading process it shuts down and does not show any signs of life until you leave it charging for another hour.The voltage output out of the power supply shows 14.70 ~ 15.20 never gets to 16V. Now, comes the questions...

This particular laptop needs a good battery to " buffer" power and the AC adapter only charges the battery but does not have enough Amps to run the computer without the battery?

or

Do i have a Bad power adapter that is not even charging the battery properly?

or

Bad power supply and battery?

HP Pavilion 360 Lockups :: Laptop Won't Turn On But The Power Button Is Lit Up

Oct 28, 2014

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?

Dell Inspiron B130 :: Plugged In With Battery But Power Will Not Turn On At All

Apr 8, 2013

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?

HP Pavilion M6-1045DX :: Laptop Power Light Flashing And Won't Turn On

Sep 1, 2014

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.

Acer Switch 10 :: Won't Turn On Or Charge Battery After Changing Power Plan

Nov 20, 2014

The computer is in dead state the next morning after I switched its Windows power plan to high performance. In order to unlock power plan options, I disabled connected standby via a registry key in HKLMSystemControlSet001ControlPowerCsEnabled to 0.
 
After investigating, I read that this computer doesn't support normal hibernate wake-up process other than connected standby. I select shut down option in the menu (hibernate option disappeared). It's possible that shut down option in the menu was actually set to sleep/hibernate in power settings by default.
 
The battery was at 100% before I last turned it off.

The LED power indicator doesn't light on when power supply is connected on either DC or microUsb.

Dell Inspiron 3542 :: When Turn On Laptop On Battery After Starting Windows It Freezes

Oct 18, 2014

I have some problems with a new Dell laptop (bought a few weeks ago). The model is Dell 15.6'' Inspiron 3542. I've searched on google and on other forums but i didn't found something useful for my problem.

The problem is that when i turn on the laptop, running only on battery, after starting the windows, it freezes. If i turn on the laptop, with the AC adaptor plugged in, it works perfectly. But if i remove the AC adaptor, the laptop freezes after a while. If i turn off the laptop without the AC adaptor plugged in, the screen goes black but the laptop dosen't shut down completly, it freezes. And every time it freezes, the only way to shut  down the laptop is to press for 5 sec the start button. I can use the laptop on battery mode, only on "Safe Mode" option of Windows. 

I'm using Windows 7 Ultimate 64 bits, and i installed all the drivers from Dell support site.

Dell Inspiron 1464 :: Laptop Can't Power On Despite Battery Indicator Lit

Feb 15, 2013

My dell laptop model is INSPIRON 1464.

Recently, it can't power on. Assuming that it was a static-flea problem, having happened before, I did the "remove the battery & AC power, holding down the power button for 30 secs" solution countless of times. Yet, to my dismay, it still couldn't power on.

I did notice, however, that each time the battery and the ac power were in and the socket power on, the battery indicator and the ac power cord were both lit. With this, I am certain that the AC power cord is working, and probably the battery is as well. I have also tried directly relaying the ac power to the laptop without the battery attached but failed.

Dell Studio 1749 :: Stop Charging - Laptop Won't Power Up With Battery Removed

Mar 8, 2010

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.

HP/Compaq :: Laptop Will Not Power On

May 2, 2010

The other day I was shutting down my laptop and it paused as normal to install the latest Windows updates. Later that evening I went to power it on and nothing happened. I immediately check the power brick and it's power light was on. Then I swithched to batter and stll nothing would come on. It's as if no power is gettng to the laptop.

I remember a similar thing happened when my hard drive connector failed, so I swapped them out, but changing that had no effect.

what I'm failed to check or what could be wrong before I have to pack it up and send it back to HP?

HP/Compaq :: Is There A Dock That Will Power Up And Down The Laptop

Apr 15, 2010

I'm planning on purchasing an Elitebook (8740 maybee) that I want to semi-permanntly dock to a monitor and external keyboard. But I dont like the idea of having to open the lid, power on the laptop, close the lid and then use my system, so I was hoping there is a docking solution out there that would have a power button mounted so i could power the laptop on and off with the lid closed.

HP/Compaq :: Hp Zv5000 Weird Power/battery

Aug 26, 2009

I have a old hp zv5000 and it seems to randomly shut down, the problem is very peculiar. The battery on the hp cant hold charge for more than 10 minutes but the problem lies in the charger/laptop itself. The charger only seems to be able to charge the battery and the system only seems to runs on battery power, the battery runs out and the system shuts down (without any notice). When the battery is taken out of the system, it fails to start up.

i am guessing somewhere in the mobo :S since the laptop itself cant turn on external power when the battery is disconnected and only seem to run off battery power.
