will not boot up




After pushing the power button, it shuts itself off 3 to 5 second after pushing the power button
It could be a problem with static discharge , if so do the following.


1. Disconect the power cord


2. Remove the battery


3. Hold down the power button for 30 seconds , then release for 30 sec and then hold down for another 30sec


4. Plug in power ,replace battery and power on laptop.


If this causes no Joy try this.


Remove memory and reinstall one stick at a time, if there are more than 1 dimm of ram, try each stick in each slot one at a time to see if the memory is ok and to determine if one of the memory slots is bad.


Hope this helps
If you hold down the button for a couple minutes, will your computer boot? If so, there's probably just something wrong with the switch. the softest way to power down the system is using the gui or:

systemctl poweroff

the second one is:

shutdown --halt now

and then pressing the power button lightly.

[how to reboot / t…](https://archived.forum.manjaro.org/t/how-to-turn-off-your-frozen-computer-reisub/124762/1) > Hello. I have an HP Pavilion 4500 laptop and it won't turn on. I've tried everything to get it to turn back on. There are no flashes or beeps or anything when I hit the power button. Also, before all this came up, my charger wasn't charging correctly. It would turn on then turn off repeatedly. Then one day, my laptop shut off and didn't come back on anymore. I haven't been on my laptop in about 4-5 months now. Could someone please tell me what might be wrong with my laptop?

you havent used it in almost half a year!!!! get yourself a correct charging unit for it that works properly and charge it. leave it out in a warm spot for a day before hand though. it sounds like its gotten very cold internally and also all the battery power has seeped away to nothing. this happens with rechargable batteries after a while. of course you wont get anything when you've got a dead battery. sounds like the charger you have already may be defective or your current battery is defective at least.  

At the other end of the scale though it could be that you laptops power supply unit has become defective and maybe that has blown.  

Rule out the simplest options first of it being the charger or battery. if theres no joy take it down to a local computer engineer and get them to have a look. be prepared to spend a little dosh on it.



btw what r your laptop specs?? might help us.:D If the security light is blinking it will not start. The security system needs to be reset. You will have to have a fully charged battery to reset the system. With a full charged battery turn the ignition forward until the warning lights come on and leave the key in the on position for 15min. Turn key off and wait 10sec. then try and start.You may have to perform this procedure a couple of times, however, it is usually successful the first try. The reduced power light can be set by a low voltage/poor charge battery problem is a bad capacitor on the power board. caution if repairing yourself as capacitors in tv's hold a charge long after set is powered off and can be lethal. 
  
 when looking at your power board for a bad cap look at the top of the capacitors. a bad cap will have a noticable "bulging" on the top of it compared to others. be sure to note polarity of capacitor (will have a "-" on one side indicating negative. to fix on/off issue simply unsoldered bad capacitor and solder in a new one with same voltage and capacitance rating being sure the new capacitor is oriented the same as the old one was before it was removed. if it doesn't turn over... it can not start!!... do you mean it cranks ok .. but will not start? I don't know that printer. But Arduino has a feature that a USB connection causes a reset. The Idea is that this helps when doing software update as the Arduino Boot loader will be active for one second after that reset.

 This can be disabled, but needs hardware modification. Hello,  
  
Put in new batteries and try again.  
  
If new batteries did not solve the problem, the next thing to check would be the battery terminal.  
  
If
 the battery terminal is rusty, the battery power won't contact and the 
calculator won't turn on. So, use a flat small screw drive to scratch 
the battery terminal so that there would be contact.  
  
If the above
 is not the problem, the next to check would be the wire connecting the 
battery terminal to the the calculator's main board. There is a wire 
between the battery terminal and the calculator board. When the battery 
is inserted, the power from the battery goes from the terminal to the 
board through this wire. There is a possibility that this wire is cut 
in-between or is loosing contact. In this case, you need to get a small 
screw driver and carefully disassemble the calculator in order to check 
the wire.  
  
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.  
  
If non of the above helps, then it means the calculator is dead and needs a replacement.

Please try this Press the 'Input/Source' Button > Press '2, 5, 8, 0' on the keypad of the remote > Scroll down to "Reset All" and press "OK" > Select "Yes" and press "OK". and let us know. My Bose wave radio (w/cd ) was purchased in 1999, it was working fine untill it quit. Power is gone. What could be the cause and how could i fix it or can it still be fixed?
