Long Tone, Power Button Flashes, No Boot

I woke up this morning and my G4 had blurred grey screen with black lines.. looked like nothing really, except the computer was frozen. I restarted and was greeted with a long tone and the power button flashing rapidly for several seconds then going off. I can hear the power supply is ON and the fan is blowing. The little red lights on the motherboard are on, but none of the drives (dvd/harddrive) are running. Nothing appears on the monitors, its dead. I haven't changed anything (software/hardware/settings) for months... I tried hitting the button next to the battery inside (as described in another similiar posting), and I even replaced the battery, no change.
Any ideas?
Thanks!

Thanks again for the tips... I have always kept everything (external devices) removed from the start of the problem... there's no chime... I have reset the ram & video card. That did resolve the loud tone and flashing power button, but nothing else. no, the hard drives don't fire up... the video card fan spins...
I've reset the PMU, removed the battery (i even replaced it with a new one)... I've been through the tutorial pages.. all of the standard stuff.. no change in the machine though.

Hi
6 years is a decent life for a laptop & I assume its a very good laptop you have, otherwise it may not come through all these years,
Ok, I'll try helping you here to revive him,
I assume your laptop came with Windows Vista
What happens when you remove the battery & connect it directly to AC adapter, is it powering on?
Whats the age of battery - 6 years? - may be its stopped working. Try another compatible battery if you've one, if it works a replacement of battery is warranted.
Try doing a hard reset first
Is it coming back?
Still nothing is coming - then,
Troubleshoot by following the HP documents given below promptly:
HP Notebook PCs - Computer Does not Start (Windows 7, Vista, XP)
If you're able to boot after doing hard reset, troubleshoot by following this:
HP Notebook PCs - Troubleshooting Black Screen Displays with No Error Messages During Startup or Boo...
If nothing is coming after all these, & you want it back you may give a visit to local technician to sort out the issue,
Or Contact HP.

X1 Carbon Touch: have to push the power button twice to boot the system

This is what always happened when I booted up the computer:
First time when I pressed the power button, the computer was on for just 2-3 seconds showing the "Lenovo" logo, and then automatically went back to power-off with nothing happened further.
And then I pressed the power button again, the computer booted and loaded the operating system without any problem.
Even though I'm able to start the computer in this way eventually, it is very annoying. It happens every time when I cold started the system (no such a problem if I simply restart the computer). Anyone knows why I have to push the power button twice to boot the system? I suspect it's something related to the rapid start technology, but cannot locate the exact reason. Anyone else has the similar problem? I have a Windows 8.1 now, but the problem existed when I was still using Windows 8. After I upgraded to 8.1, the problem still exists.

Power button flashes on 22" Cinema Display with PowerMac G5

I just bought a G5 and and ADC to DVI adaptor. I'm connecting to a 22" Cinema Display. Everything works fine on the display, except the power button flashes. I'm wondering if anyone else has run into this issue.

The power button flashing indicates some type of hardware problem with the display. You should call AppleCare or check the documentation to determine the exact problem by the number of blinks and pauses. Even though it is working now, there might be a problem that will soon manifest itself.

T510 boot issues - power button flashes

I have a T510 that is acting really strange.
The laptop will do the following once shut down for any extended period of time.
When I open it up and press the power button the power button, keyboard light , hdd light will all flash. 5 seconds or so will pass and then it will do the same thing, never actually booting up. I'll pull the power and batteries and repeat the process and the thing will do the same thing. Eventually it will boot if I repeat the steps enough.
This just started happening recently. It will run fine once the system actually turns on. I have updated all drivers, I have updated the BIOS and all other software. I am highly doubting this is a windows issue as it never even POSTs.
The flashing lights almost act like an error code but I couldn't find anything regarding 1 quick slow flash by the power button.
Any suggestions?

Maybe the keyboard cable or the keyboard itself? Nothing shows on screen during a false start?

PowerMac G4 MDD power button flashes but doesn't boot

My PowerMac G4 MDD will not boot when the power button is pressed. The power button lights up for about 1/2 second and then goes out. There are no noises at all. No hard drive spin-up, and no fan.
For the past few years, in order to get the machine to boot up, it has been necessary to unplug it from the power source and plug it in again. I have read about other people having this same exact problem and remedy. Now, however, doing the unplug/replug thing no longer gets the machine to boot. The power button will light up briefly only after an unplug/replug. Subsequent pushes will not cause it to light up until another unplug/replug is done.
I have removed all peripherals, including the video card (only card that was in the machine), 3 of the 4 RAM modules, disconnected the hard drive and DVD drive power cables, and disconnected the fan, and removed the PRAM battery (which I know is probably dead), and this makes no difference in the behavior: The power button lights up for about 1/2 second and nothing more. I also disconnected and reconnected the power supply cable to the motherboard. No difference.
There seem to be 2 possibilities: I need to get a new PRAM battery and press the PMU reset button, or my power supply has gone bad.
Before I buy a PRAM battery, I am investigating the power supply to see if I can tell whether it is good or not. Some people with similar problems have discovered blown fuses in their power supplies. Before I open up my power supply and look for that fuse, I have a question for anyone who had that fuse problem: Did your power button still light up, even briefly, when your power supply had the blown fuse?
Best regards,
Dave

Power button flashes three times in regular intervals!

Power button flashes once and wont turn on.

When I press the power button on the computer the power button light flashes once and won't turn on when I plug the a.c. adapter in it shows that it's charging and plugged in, but anytime I press the power button it flashes once but will never turn on! :/ I tried unplugging the adapter hold the power button for 30 seconds and connecting the adapter back to the computer but it does the same thing.. Any advice would be AMAZING! Thanks !
The computer is compaq Presario cq62-215dx

Remove everyhting from your pc. INCLUDING KEYBOARD. and try again. On 2 different occassions the keyboard was to blame. Some spill on keyboard caused motherboard not to power up.
Remove KB, Ram, Hdd, DISPLAY (Lcd cable might be shorting as well) etc.etc. Leave motherboard alone but power sithc connected. Even if you disconnect the fan cable it would help. If you see anything on your screen after you removed fan too then turn it off immediately and connect the fan back and try again then add up other components one by one. If none works then i am sorry the board you have is faulty.
or it may need a bios recovery.

Power button flashes when I try to scan HP Deskjet 2514

I first had a problem where my printer would not stop printing, even though I canceled it. I looked it up and followed these instructions. From the Desktop, hold down the Windows key and press R. Into the Run window, type services.msc and hit enter. Browse down to the print spooler service, right click it and select Properties then click on the Stop button. Now browse to C:\Windows\System32\Spool\PRINTERS and delete the job inside this folder - You may need to click a prompt to gain the appropriate authority to open the PRINTERS folder. Restart the computer and you should find the document(s) have been removed. I didn't know which one to delete, so I deleted everything in the folder. Now, my printer will print, but everytime I try to scan something, my power button blinks and it won't scan. Please help!

Hi , I read your post and see that you were able to resolve the issue for the print jobs not cancelling out, but now you are unable to scan. I would be happy to help you.
Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector) This ensures the printer is receiving full power and may help this situation. Download and run the Print and Scan Doctor, it will diagnose the issue and might automatically resolve it. This software will also troubleshoot jobs stuck in the queue, which you could use in the future if the issue occurs again. What were the results when you ran the Print and Scan Doctor? (did it print or scan, any error messages) If you appreciate my efforts, please click the 'Thumbs up' button below. If there is anything else I can help you with, just let me know. Thank You.

X220 - no post and green light around power button flashes every 3 - 4 second

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. All of them with the same problem that is described in subject. Are there any known batch issues?
The problem is not with the tablet version and sorry for posting in the wrong forum.
Thx
Solved!
Go to Solution.

All,
Thanks - interesting experiences. Could you each send me a private message with any additional details including the model type and serial number of the units? We can look into this.
Also, as the discussion continues, please include more details about what BIOS version you are running, any updates that were recently applied, etc. Please also describe the symptoms - does everyone have the blinking power indicator?
If you reset by pulling the battery & AC and pressing and holding power button several times for several seconds, then re-attaching AC, does the system restart? No video? Any beeps?
Lastly, if you are seeing a high percentage of failures of your install base, please contact your account rep so that we can get the right level of resource involved to help resolve this. If you have a single system, please call service if you are unable to reset the system.
Thanks!

Press power button, No post, No Video. 20 seconds later power button flashes many different colors

Hi, Hope someone can be of help here. Working with one of the newer A135's w/ vista. Plugged in all looks good, charging light and all but when you press the power button all looks good at first but about 20 seconds into unit powered up, no post, no video no nothing I get the power light bar changing colors, it goes from dark blue to light blue to orange to amber to green and starts all over again. It appears that there are not too many people with the same problem so only actual support would be appreciated. I can solder to component level so if anyone has a schematic and area of potential search for the bum chip it would be greatly appreciated!

Hello Chatbox,
I can understand your issue very well, as there is no message comes on the screen which gives you information to plug the power adapter and prevent the laptop to get shut down.
You should install Power Manager software and then customize it as per your requirement.
The software can be download from the mentioned below web link.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8mu417ww.exe
Hope, after this laptop will not shut down automatically due to battery backup
Best Regards,
Tanuj

How to configure X220 to ignore power button and only boot via fingerprint reader?

Hey all, sorry if this has been answered. If it has I haven't seen it.
Is there a way to set the BIOS to only bot via a successful fingerprint swipe? this seems like such a better way of doing things. I am interested in security, but only so interested that i can swipe a reader instead of hitting a button; putting in a password every time and that is way too much effort for me. But when I swipe an unregistered finger, the computer stays off. When I swipe a registered finger, it turns on. Thats awesome. Now how can I make it so I ONLY can turn it on that way instead of just pressing the power button?
Solved!
Go to Solution.

welcome to the forum!
short of physically modifying your keyboard, it's not possible. if for some reason the FPR were to fail or fail to read a configured finger then there would be no way to turn the system on.
the system is no more or less secure with an enabled or disabled power button. anyone who really wants your data and actually knows what they're doing doesn't need a working power button to get it.

GE70 2PE Apache Pro Power button flashing Blue and Orange

It does this every few seconds and it just worries me a lil. Just hoping it's nothing serious. I haven't noticed anything wrong software wise but, could it be telling me something is wrong internally hardware wise?
Thanks

Do you have MSI Afterburner, GPU-Z, AIDA64, or any other programs that MIGHT check the GPU's on your notebook? If so, close them. See if it continues happening.
You can also enable the "Display GPU Activity Icon in the Notification Panel" in your NVidia control panels -> Desktop -> Add a checkmark next to "Display GPU Activity Icon in the Notification Panel"
This will add a small box down in your notification panel (by your clock) and you can mouse over it to find out what program is causing your GPU to get enabled. This can help debug the problem as well.

I've never seen my 'power' button illuminated!?

i personaly quite enjoy the illuminated keyboards function, it not only looks cool but very useful, however, i've never seen my power button illuminated.
even when i updated firmware, you know, after you installed the update software, it will need to shut down the computer, then you need to hold the power button for few seconds until you see the button flash..... i did every step they said, but never seen the power button flash, instead, i heard a long BEEP, my firmware update has been successful, but i am worried about my keyboard, specially that power key, any idea how can i 'light' it on?
thanks

Ooo.... I didn't know it was ment to have a light.
I thought when i first saw it it looked like a light,
but mines never turned on. My keyboard lights fine,
as does the sleep light.
Now I'm worried.
it seems that not only me have this 'problem'
