Question about HP Computers & Internet
Power cord fairly new...wont turn on now and the power box from cord has a high pitched beeping
The surge protector that is sometimes included in the power supplies for laptops will emit sound when they have failed. it is also possible that there is a building power fault (ground not connected).
what model is the adapter? it would help a lot. also, which laptop is it?

Check these settings first. In a clear spot on the screen where no icons are, right click and go to properties, box opens and at top should list from R to L, themes-desktop-screensaver-appearance-advanced. click on screensaver, close to bottom click on power, another box should open, click on power schemes, make sure it's set to portable/laptop, and at bottom make sure settings for plugged in are are set to never. If it's not that then you have a bad power supply cord, or a bad power supply unit in laptop. If it's new and under warranty take it in and have replaced if not warrantied then will cost you about 100-150, just a guess!! hope this helps. But it sounds like the supply cord making the beeping noise might be bad. Make sure it's plugged all the way in as well.
