How do I factory restart on my hp notebook pc you meant restore/recover the OS to new day 1 state,.

hello OP

yes, and is covered in you manual. at HP.com


HP 15 is not a full model number, stated so....
my guess not HP 15 ENVY. but to progress here, I will guess.
over 200 models with that short name exists.
huge models. I guess one is your?
https://support.hp.com/us-en/products/laptops/hp-notebooks/
you left out all those facts in the model.
but all modern HP , you CAN do this,

power on, and hammer f11, this runs the magic RECOVERY
that restores the OS to day 1, new, all data you created gone.
as the book says, and is true.
but if the HDD is bad (or molested or upgraded from other OS)
it ill fail.

no OS stated by you, Windows XP,Vista, 7,8 or 10, ?
is the OS same as new?/?
save version?????????????????????????????????????
HP tells me it came with W7 64bit, tell me its not W10 now.




the F11 key, that way, you need to tell how you did that.
what method (there is not just one method)
the F11 key full recover takes a good HDD,
we do the hdd tests first.
or its all just a waste of time.
DV7 is old. so what do techs do old.
1: new coin cell, is yours 10 years old, and hopeless.....??????
2: main battery out do not do what you did with the Main huge bad battery installed use only the AC power pack to run now.
3: vents clean if the PC overheats how can it reInstall OS ? cant.
see slide show for LapTops. if packed it will overheat and fail.!!!
http://pcdied.com/overheated.html
4; we test the HDD next using linux. (free if you have blank CD or Thumbdrive. do the smart tests then the full drive test.
http://pcdied.com/linux.html

5: ok the HDD is bad, new HDD and buy new OS yours is gone.
6:ok HDD was good , but F11 is messed up only.
if F11 is messed up that means the HDD was slammed.
that means (alien OS installed or using wrong media, not from HP)
If someone damaged the HP C:/recovery partition , then F11 is doomed. for sure.

if the computer has in built recovery then you can restore the computer to factory setting.as you restart the computer stat tapping f10 if there is recovery t will start automatically.In case this do not work then contact hp they will send you new restore cd.

Hi,
If the laptop didn't come with restore CD's then chances are that there is a hidden recovery partition on the hard drive that you need to access to recover it back to factory state.
Restart the PC and press ALT+F10 to get into the recovery mode and restore the laptop, you can also try empowering technology, eRecovery software to restore the machine.




Good luck

If your OEM is original from manufacture, and this option was installed. Restart PC, at the HP intro screen type "f11" 4 times, choose recovery, make shure you choose "restore to manufature settings" gl hope this works for you.
