Samsung r540 power on switch - Samsung R540 Laptop

Hi Judy,

please enter the webpage http://www.samsung.com/us/support/owners/product/NP-R540-JA04US

and click on User MAnuel. its a flash so you will need flash player installed in your computer.

this isn't a question at all and you should feel silly

lets try something...take the computer and unplug it ..then remove the battery...with the battery set aside plug the wall plug back in and plug that into the wall outlet....then hold down the power button for about 2-4 seconds and let me know if it turns on or if there is any changes
then try a different power cable and if that doesn't work then the problem is with your motherboard....you can attempt to reflow the board by taking it all apart...make sure you remove everything that can be heat damaged...cpu ect.....then take aluminum foil and make 3inch soft balls out of it to suspend the motherboard so that it doesn't touch the cookie sheet pan....then bake at 400 for 10 mins...and after that if it still doesn't work then you need to replace the motherboard

take out battery then wait 1 min then put it back

If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Do you have the bluetooth driver installed? If not, go to http://www.samsung.com/us/support/owners/product/NP-R540-JA02US# and install it (first one in the list on the 'Drivers' tab - Bluetooth,BROADCOM (Driver) (ver.6.3.0.8800))

There's also a manuals tab there. It might give you some more info about how to actually use the bluetooth.

It sounds like your power supply has died. I would suggest a replacement.
You also may need to reseed your ram as that may sometimes be the issue.

Have you tried system restore?

Hello Armiriyala, from your description I can analyze that this is not the problem with Hard disk, laptop never dead with problem of a hard disk, probably this can cause by damaged charger, please check your charger first, if the charger is ok there is might be a chance of power section fault of laptop....
I hope this is useful to you

rate me thank you
