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?

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.

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.

When my laptop is plugged into AC power, and I decide to move to another room and unplug it, the laptop suddenly freezes. All the programs do not respond and the only way to fix it is to reboot.
HP tech is trying to help my by telling me to test the battery life and resetting the bios, however this laptop is only 2 months old and I had the problem since the begining.
Its a dv3 Pavilion.

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).

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.

My HP 250 laptop is barely 6 months, a few hours ago I shut it down, and just when I tried to power it again it won't come on,the little light close to the charging port that indicates if the laptop is charging won't even blink, I've tried several stuffs like: removing the battery, and connecting the charger directly,I also removed the ram and put it back. Now my laptop isn't charging, with or without the battery, and it won't power on. Its just completely dead, what could be the problem.

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.

I'm having major trouble with my laptop (an Acer Aspire 3660) which is about 2 years old now. I don't know if there is a problem with the internal power socket or something else, but sometimes when it is plugged it just won't run off the mains or charge the battery. Sometimes I can get it to charge up, seemingly by rotating the power cord cable but at other times it will randomly go to battery even though absolutely nothing has moved, and sometimes it will go to battery power with the slightest little nudge. I don't think this could be related to the battery as the battery seems to work fine (although it does drain quickly I guess it's pretty old in laptop terms). Has anyone else had this problem or have any suggestions? I bought a new power cable (completely new including power pack and the plug end) but the problem still happens.

My HP G71 computer will not power on. It was fine 2 weeks ago then went on holiday, came back and won't power on. Have taken battery out, disconnected power cord. When re-installing the light shows up on the side of the computer where the power adapter goes and the 3 lights come on the front of the notebook but then after a minute or so goes off.

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.

I was having issues with my laptop(keyboard stopped working, mouse jerky, trouble booting), and after a lot of research found that a common acer problem is that the bios is the wrong version, and that it needs to be upgraded. so i downloaded a bios upgrade off of the acer website and ran it.
now my computer will not boot up, pressing the power button does nothing, it doesn't even light up.
i'm assuming that it was a bad bios flash, and i'm wondering if there's anything i can do to fix it.
my computer is an acer aspire timeline 5810tz-4657, 320 gb ram, intel pentium processor, 3 gb ram. i had windows vista and ubuntu v 10.04 installed on it prior to the bios flash.

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.

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 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?

just got an Acer Extensa 5420-5687 laptop (used no warranty), added a new hdd and plugged in and I get nothing, the battery light does not light up, I swapped power supplies with my 5102wlmi and I still get nothing, no lights no nothing I have a feeling I know where this is going which might be the trash bin, but I thought I might ask if there is something I should be looking for. I have tried holding the power button without a battery and all that neat stuff. The battery charge light does not come on at all, its been plugged in for about an hour now and I get nothing.......

My laptop is refusing to accept the charger cable so I cannot recharge the battery or power up the laptop. The original charger broke but I have tried a new Dell charger and it will not work.

my Inspiron 17R no longer recognizes when it is unplugged from the AC adapter. This means that when you check the power icon it always claims to be connected, even if it's not, and that the charge meter basically can't be trusted (it'll say it's fully charged when it's not). It also means that it fails to adhere to its power plans because it never goes into battery-only mode. I have contacted my local Dell tech support, but after checking my bios and seeing that my computer recognizes the AC adapter, they didn't know what to do. how to get my laptop to properly recognize when it is and isn't plugged into the power supply?

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?

This is a late 2008 build Dell Inspiron 1545, sold retail in December 2010.
Pentium dual core T4500, 2.3 GHz
Has been in irregular use as a spare machine, mains adapter only, battery removed. My house was struck by lightning over a year ago and adapter damaged. Replaced adapter and no further issue until now.
Laptop would not power up, no light. Tested adapter and tried another 2 adapters - still no power up. Replaced original adapter and plugged in depleted battery - powered up but had to press F1. Powered up with no issue with good battery. Once powered up the laptop seems to be charging battery OK. Guessed this was a power board issue but no change when replacement fitted.

My new XPS laptop is just a few days old and I'd like not to kill it prematurely. What is current consensus on best practice to extend useful life? Shut it down after session completed (i.e., in AM when leaving for work) or leave in standby "sleep" mode? I leave my employers Dell Latitude computer powered up in a docking station during the week but power it down for the weekend. With current electronic semiconductor technology, is there a negative aspect on longevity (inrush current, for example) by daily shutting down and powering up?

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.
