Laptop turns on by itself when plugged in

[ Edited ]

1. Product Name and Number
HP Pavilion DV2540ev 
2. Operating System installed

Windows Vista 64-bit

So,i have the above HP Pavilion with windows vista installed.All of a sudden when i plug in my laptop to the socket then the laptop just powers on by itself without me pressing the power button.The same behaviour occurs with the battery attached to it and with the battery removed.In both occasions the laptop just powers itself up when i plug it in.

I have tried a bios reset but didnt seem to do anything.

Any suggestions?

Re: Laptop turns on by itself when plugged in

So should i assume that no one from the HP staff knows how to deal with that kind of problem?

Hi Onyx,

 

Don't know about HP staff - This is HP Forum, staffed by HP computer owners, users, experts - some of us, newbies - others of us... and some HP people, too.  It's not Tech Support.  Smiling.

BIOS Update:

If there is nothing in the BIOS, and you've gone through all of that, then you could try an UPDATE to the BIOS.  The one on the website is from way back in 2008; nonetheless, here is the information:

 

Software & Driver Downloads - HP Pavilion dv2540ev Notebook PC

 

Select the BIOS, download, and install.

 

-------------------------------------------------------------------------------------------------------------------

Bad MoBo:

I did find something for you that sounds like a similar issue - you may be looking at a motherboard problem.  If that is the case, you would likely have to have a repair shop troubleshoot it (at the least), or maybe just replace the board.

Laptop automatically powers on when plugged in for charging

 

 

If someone finds out something that sounds more encouraging, I hope they post it for you.

 

Good Luck!

 

I hope this helps...
