HP Pavilion 15-n278sa Lockups :: Laptop Shutdown Randomly - Power Button Will Not Respond
Jul 6, 2014
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...
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 currently have a Acer Aspire V3 Laptop that runs on the most current version of Windows 8. Ran perfectly fine last night without any kind of problems. Went to get on it this morning and the power button won't respond. When it is plugged in, the LED light shows that it's charging, but when I try to turn it on, the power button doesn't respond. Every few presses, the power button lights up for a split second, then turns off. The screen never responds to the power button being on for a split second.
I am having HP Pavilion DV6 6140Tx . Installed Windows 8 Enterprise Edition and updated drivers using drivers for Windows 7 64x from HP site
The problem is that, when i shutdown my laptop, it doesnt shutsdown, it turns off the screen, but not the processor, fan, touchpad, the light and fan movement is ON and it never shuts down. Then I have forcibly press n hold the Power button to shut it down !
It also has a delayed Startup issue! But Restart function just works fine..!
I don't graphics drivers installed on the system - its AMD ATI RADEON 6700M HD - no compatible drivers available !
I have a T530 with an SSD, less than a year old, that appears to be bricked ... when the power button is pushed, there is absolutely no noise (no fan, no beeps) and no indicator lights.
I'm having trouble getting the "what happened" story out of the user but I heard something like "the battery ran out and now it won't start". I suspect some improper behavior like hauling the machine around when it was "sleeping" (not off) but that as they say is another story.
Elsenet I saw the following "one weird tip" to discharge static buildup (*)
* unplug power * take out battery * take out RAM
then a sequence where you pushed the power button 9x and on the 10th time held it for 30 seconds. Then plug power in and try again. No soap (although the ram is internal, not in the expansion slot, so I haven't disassembled the keyboard area to check).
I also unplugged the battery/power and held down the power button for one minute - still no luck
Swapped out power supply and battery - no luck
Only indications of "life" are the little battery icon on the top of the case (e.g. when computer is closed):
- Battery not installed - put power cord in, icon flashes green 3x, stops, but power button does not turn on - Battery installed - put power cord in, icon flashes green 3x, flashes long orange 1x, flashes short green 1x more
Is there something else I can try or is this a "Call IBM/Get this guy a loaner"?
* laptop appears to be staticy, I have gotten a couple of "snaps" off it, and that doesn't regularly happen
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.
My laptop wont turn on, whenever I press the power button all the lights light up for about a second, I here the fans turn on and then it shuts off. When I plug the charger in the the charger light blinks, but thats it.
Am using Delll N4050 more than a year, now am facing some shutdown issues.
Computer details: My Laptop shipped with ubundu and I installed windows 7 home premium.
Processor: Intel core i3-2350M CPU @ 2.30 GHz
Problem: For past one year it was working fine but now am facing shutdown issues. When I shutdown my laptop it's not shutting properly (i.e.) power led keeps glowing and fan keeps running until i long press power button to shut it down. But restart works fine. Same problem occurs when I put in sleep mode and hibernate mode.
System Will not Wake Up from Sleep Mode / power button continues to glow even when shutdown option is selected Motherboard failure due to any internal short circuit could be the reason of this technical glitch...
So recently my laptop started randomly shutting off while I was gaming, I assumed it was the graphics card so I tried to use the intel hd graphics and disable the amd hd graphics to see if that would solve the issue, however it still happened. One thing I noticed is that now when I disable that graphics card the resolution is odd and the letters won't be as clear, I'm guessing this means it may be a motherboard issue.I moved on to thinking it was overheating due a fan problem, I bought a new thermal module for it and the same thing still happens.
I did the reset procedure (removed the battery and ac, pressed the power button for 60secs) and it still happened. I tried with a new battery and charger, same still happens.Lately it doesn't happen just while gaming, it will randomly shut down and once it does, sometimes it will shut down again and again before it even boots up, after a while it may boot up or may shut down again.It's really random and I cannot find a pattern....
I bought this HP Split X2 about two months ago. When I am working on it, if I move and the screen moves ever so slightly back and forth, it will completely shut down. I have to adjust the screen to a angle where the power button will turn it on.
Really odd issue. My touchpad does not respond at all after I wake the computer from sleep mode. The mouse buttons do not work and the touchpad is completely impossible to get to move. The only solution is to shut down the computer entirely and turn it back on.
Does anyone else have this issue? I've re-installed the mouse drivers and it keeps doing it. There is no way to re-create the problem; it just happens totally randomly (and usually very inconveniently).
I have Hp Pavilion 2000 notebook, on which when i am press f2,f3 for brightness increease or decrease, id does'nt do that. inface all other buttons are performing well, but when i press this, the brighness bar shows on the screen but newither it increases nor decreases.
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've been given an HP Pavilion G6 laptop that belonged to someone who passed away. It asks for a power-on password, and after three tries I got a System Disabled code of 79308945. Is there a way to change the power-on password? I've read several threads in these forums asking this exact question, and people have been given an individual code to get into their machines.
I have a Pavilion G6 that won't start at all when the power button is pushed. I've tried it on battery only, and with the power cord plugged in. Yet nothing.
Here is what I see: When the power cord is plugged in, the power LED next to the port is white. I press the power button and it momentarily flashes white (and the F12 LED flashes). Nothing else happens. No other LEDs lite, and the screen remains black.
DIagnostic steps followed:
1. Battery was removed, and unit unplugged. Power button held for 30 seconds, and plugged back in. Nothing.
2. Battery removed and unit plugged into the wall. Power button pushed and nothing.
3. Tried a different power cord, different battery .. nothing
4. Removed the RAM boards, power button pushed .. nothing
5. Removed the hard drive (RAM still uninstalled), power button pushed .. nothing
When I try to start my Inspiron XPS15 L502X DELL laptop by pressing the 'power on' button NOTHING happens.
I have tried the methods suggested on the forum site (remove battery-press power button for 40 secs-put battery back -start) but nothing happens. The laptop refuses to start. No lights, no message, just NOTHING.
i have a dell inspiron b130 and every once in a while the thing just shuts off lke the bat has been takin out, no shutdown process or nothin. i know the battery is shot, i was just wondering if its the cord or the ac jack on the computer itself? i can mess with the cord by the computer and i can get it to work. but also the cord has been chewed on near in the middle between the ac plug and the power brick....
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 have a major problem with my hp pavilion dv6-3143sa laptop.
I put it to a shop and they told me it was a motherboard/cpu problem and they couldn't source parts. I managed to get the parts. I put the motherboard first, but didn't work. I then added the cpu and put on thermal paste, but still didn't work.
My laptop will power on but I'm still getting a blinking light on the caps lock button and a black screen.
Everytime I go onto the internet, try to download something, try to open a new tab my Laptop will freeze, and usually it will not let me open the task manager when I press CTRL + ALT + DEL. I have run virus scans with Norton (I am still in my free 90 day trial) and no threats have been found, I have done disc defragmenter, I have scanned the computer for errors, I have performed disc clean ups and why it is still freezing. I have also changed my Internet browser from Internet Explorer to Mozilla Firefox and I still seem to have the same problems.why it keeps freezing.
