HP Pavilion 753N will not power up...



I have a HP 753N 2.53GHz P4 Desktop System w/CD-RW/DVD.



When the power button is pushed it just makes a clicking sound but will not stay powered. The fans momentarily come on, hard drive tries to spin up, but when I release the power button it just shuts off. Have checked the internal cables (nothing appears loose).



Any thoughts to this?
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.

for more ways of shutting down your computer, see this excellent cough, cough article:

[how to reboot / t…](https://archived.forum.manjaro.org/t/how-to-turn-off-your-frozen-computer-reisub/124762/1) have added psu to above post. (i added specs because i knew someone would ask. however i think it's a software issue.)

unlikely that it's the psu.

the current psu is a hx750i, and the previous psu was a hx650i. swapped over a year ago at least. this is a recent issue.


good, a lot of times this is the psu. but with an excellent unit, that's far less likely.

were you monitoring temperatures at the time? was there something specific you were doing similar in both times? really intermittent things can be hard to nail down. 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 You can get seperate dc jacks from here

Try not to disconnect the screen as it may never come on again, i would take to a qualified repairer. 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.  
  
Regards. enable xmp. run stability testing.
if that is all good and you want to now overclock the cpu then it's time to make a new thread in the overclocking section. pat, sorry to read about your notebook issue.  be assured that i have been monitoring this post and see that you have received very helpful input.  if you're not able to duplicate the memtest86 hit, you may want to scan for "infections" as andre s. recommends.  however, along with malwarebytes, i would also run tdsskiller and combofix.   after doing this and the laptop still freezes, you may want to contact hp's excellent elite premier support team at 866 625-1175, especially if this model is still under warranty.  you also may want to pm me with the product number, serial number so i can get a case started for you or so we can discuss some hp options if out of warranty. first try testing your RAM (goldmemory or memtest)
  

  
if the memory pass the tests try reparing your xp, if repair doesn't pass from any reason, pull your HD take it to your friend, back up the data, and reinstall OS Hi Ohforf,

We understand your SSD stopped responding sometimes and after a power cycle, it starts to work again.

 

For this situation, we do recommend to you the following <https://downloadcenter.intel.com/download/25348> firmware version link to install to the SSD and fix this situation. For this update, you need to create either a USB thumb drive or a CD, once you run it and install it, please let us know if the issue was resolved.

Regards,

hence we are closing this topic. if need further support, please open a new one.
