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.

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.

Laptop was working fine up until yesterday. Then this happened...
1. Pressed the power button to turn on the laptop
2.the fans run and the computer makes its usual whirring noises as it would normally do whilst booting up.
3.the screen however remains completely inactive. As if the laptop is off.
4. I turned it off and on again several times. Once it came on and worked as normal, I could access all files and backup everything.
5. This morning I turned it back on and it has done the same thing. Makes the sounds as normal but screen is inactive.
I have turned off and on again and connected an HDMI cable to an external screen but there is no signal.

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 a new laptop as mentioned in the subject and am wondering...
The power button on this laptop never lights up at all.
I can't tell that pressing the power button has done anything at all until I see the screen come on.
Is that normal for this brand of Dell? I mean to have no light on the power button indicating that it has been pressed?

We bought around 40 of these X220 I5 before xmas and now more than 20 of them have failed. The company we bought them from tried everything but they ended up switching the mainboard on the first two that failed.
We were told it was a batch issue with the serial number R9-HNXXX and now all of those are changed into T420. But today we had the same problem with serial number R9-HXXXX that was bought two weeks earlier and with different config - I7 and SSD.

Laptop: Hp ProBook 4510s
When I turn my laptop on, the blue light on the power on button lights for 6 seconds, meanwhile the led near the power plug on right side rapidly blinks 13 times. Always exactly 13 times, so it must be some kind of error code. Then laptop shuts down. Nothing is heard, neither fan, neither hard disk.

My Latitude D800 laptop recently had trouble to turn on. When pressed the power button (no matter how hrad or hard long to press), nothing happened, totally dead, power light didn't turn on at all. I tried with battery (two batteries) only, AC power only and both, same thing, but sometimes it could be turned on when I waited for a while or came back later and tried again.

My laptop, an Inspiron 15R, will not turn on. When I press power button, it beeps 3 times. Owner manuel says 3 beep codes mean possible system board failure - chipset error. As luck would have it my warranty went out in December. Does this mean the hard drive on my computer has crashed?

I bought my Lenovo Y40 on the Lenovo Web site a couple months ago and recently, to turn on, I have to press the power button twice. When I press just once, the Lenovo`s logo is displayed on the screen, but after 2 seconds everything turns off. On the second trying, finally the laptop turns on and the windows is started.
In addition, rarely the laptop stucks on the lenovo`s logo screen, being necessary to hold on the power to reset it.

I have a Dell Studio 1558 laptop which is currently four years old and out of warranty.
Currently, with or without the battery with AC adapter connected when I press the power button, the power light does not light up but the battery status light keeps on blinking until the power button is pressed. I don't see any boot up screen or hear any sound of CPU fan running in the mean time. Basically, it does not start at all.
I recently got new dell authorized battery as a replacement for laptop fearing that could be source of problem. However, the new battery does no good. I checked the battery health and status and its fine.
Before this issue the laptop would start and immediately on boot screen it would shut down. So, I got it fixed from a repair service center who cleaned up the clogged cpu fan. It worked fine for two days and then the issue resurfaced.
Now, it does not start at all. I even checked with another adapter and also changed the CMOS battery (as date and time kept changing on every boot) but the issue still remains.
Also tried removing and reconnecting the RAMs one after another and then trying to boot. Also tried draining the static charge if any after removing the battery and adapter and then holding the power button for 50 seconds. Reconnecting with ac adapter with or without battery then also does not start the system.

This morning, my Inspiron 3721 (18 months old) failed to turn on. Worked fine last night.
Symptoms: on pressing power button, only power light illuminates, but no other noises, no fans, no screen response.
Have removed battery, removed power lead, held down power button for 50 seconds. Reconnected battery & power lead, but no change to above behaviour.
Tried a different power lead but no change to above.

I have a dell inspiron 15r 5521 laptop. Yesterday when I tried to turn it on it won't boot, even the POST or the BIOS won't show up. I removed the battery and power supply and press down the power button for a long time and repeated it a lot of times too but no luck. I removed the HDD, RAMs and the CMOS battery and kept it that way for 5 mins and put them back in but it was still the same. I noticed that whenever I enter the ac adaptor into the laptop the fan moves for like 100millisecond and the light on the caps lock button lights up for the same amount of time then it all goes silent. Same happens when I press the power button with only the battery inserted.
All what happens when I try to turn it on is that the power indicator light on the laptop turns on(white color, which is the normal color for this laptop), and that's it. The light don't blink or anything at all. No beep sound. The fan, HDD everything remains silent. Only that light stays on until I unplug it from ac and remove the battery. Pressing down the power button doesn't turn it off either. No other indicator light such as the wifi's, hdd's, battery's light doesn't turn on.

Today suddenly when I press the power button laptop wont turn on at all. It is also plugged in.
I hear people saying when this happens they say remove the battery and hold the power button for 15 seconds but the battery is built in and not removable
Any way my laptop is just 5 months years old and what might causes this problem now?

I have an Acer Aspire V3 551 8469. It is out of warranty. The indicator power light blinks 4 to 5 times and nothing happens after. I got adventurous and opened it up. I replaces the cord that receives the power coupling from the ac. Still not working. I was told it could be the motherboard but there is no guarantee that is the issue. If it is the mother board I will just have to get one and put it in.

For about a month or so my Vostro V130 has not been turning on. Upon pushing the power button, the power button itself lights up for a second at most and then cuts right off. During this time, the screen remains black and nothing else occurs. I've tried turning it on while plugged in and charging and tried turning it on after being charged an hour or so. Everything yields the same results.

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.

I've had my laptop for about a three weeks now. Last night, I shut the lid to put it to sleep and went out for a few hours, leaving the lap top plugged in.
When I came home, the laptop wouldn't turn on. I looked online, found to take out the battery, hold the power button down for 30 sec, put the battery back in, then plug it in again, nothing worked.
I left the battery out over night, then did the same thing -- no go.
The computer has been plugged in for about an hour now, still nothing.
There are no lights on the laptop itself, the green light is on the AC adapter and I also plugged in the adapter into another computer and it worked with that.
Running on Windows 7, Inspiron 17 5748 -- still under warranty.
