New ac adapter not working

[Imm00ral]

My power supply seemed broken - no light on the adapter, not charging computer. I just received a new one, but it has the same issue.

Sometimes, the light on the new adapter will come on for a second when it is first plugged in. the computer's battery light also comes on.

The only difference between adapters:
Old adapter input was 100-240V ~ 2.25A. New one is the same but 2.9A.

Hi,

It may not be the AC adapter that has the problem but the laptop itself. Please do try these troubleshooting steps that may help.
- First, do try booting up the laptop without its battery connected.
- If it will still not boot up, try to reseat the RAM's, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- Next is to also try connecting an external monitor when you see the laptop lights up and see if you'll get any display from it.
- If there's still no display on the external monitor that could only mean that the problem is the motherboard itself not the AC adapter.
