msi all in one winddtop ae2020 is dead

Hi i got a msi ae2020 from a frend and its just dead the ac adapters led is on but when i plug ot in it starts to flash , ive opend kt and everything inside seems to be in order. Im all out of idease , can sumone please help ?

 

Thanx for the reply , its not a laptop its one of those flat screens with a built in pc , its the light on the ac adapter that flashes when you plug it in when its not pluged in it dosnt flash tho

 

It's worth trying a different adapter. The green light on the power supply only indicates there is power - not how much. I've seen a few adapters that have failed where the output drops to the point it will neither charge or power the PC but the green light stays on.

I've run into this a few times in the past few years on repair issues in my shop. I can't guarantee it will solve the problem; however it's worth a try.

 

I have similar issue with an AE2020 I'm investigating on behalf of a neighbour. Unloaded, the PSU puts out 19v and the LED lights. Plug the PSU into the unit and the LED extinguishes.

It's either a faulty PSU or there is something in the PC that pulls a lot of current and the PSU has a self-protection circuit and shuts down to prevent burn-out. I know not which but I have seen reference to this fault elsewhere on the web.

Buying a new PSU only to find it's a fault on the PC isn't a sensible option so I'm looking for insight as to which is the more likely option from anyone with experience of same.
