Laptop does not boot

[mrnike75]

Hi everyone,

I swapped the power port of my laptop which had a loose connection. After assembling the computer again, i had the bad surprise to notice that the power button had not effect at all. The fan does not spin, no video, no sign of life... However, the led of the the power port is working properly, and even turning to orange if i connect the battery. I checked that everything was connected properly. I didnt find any issue.

Except the l'Oise connections, the computer was working perfectly before i swapped the part.

So, is there something special to do when swapping the power port, like a special reset or something ?

Otherwise, do you guys see any other solution?

Thanks in advance.

You may have left a connector loose or inadvertently damaged something.

I suggest taking it to a laptop/PC shop to have it inspected and repaired.

I disassembled everything again, checked again no connecter unplugged. Then i closed the cover and plugged it in with the battery (which is almost dead) pressing the power button for 15 seconds. The computer booted until the HP logo, then turned off. With every boot attempt (long pressing the power button) the boot would go further, and the 4th time it even initiated the windows boot. Then i removed the battery and the computer refused to boot... Very strange.

Looks like the electricity works for charging the battery but not for running the computer. 

I need to hard reset the computer, someone would know how to do that ?

I pressed 15 sec on the power button, computer unplugged, not battery. Now the computer boots normally (no long pwr button presse needed), but only on the battery.

Problem resolved.

Charger was not powerful enough.

So you were not using the original power adapter?

That's right.

I read somewhere that if the battery was charging but the not computer running, the PSU might not be powerful enough. That's where i realised i was using a 45 or 65w one instead of the original 90w power supply 😉.
