My aunt has an HP15 laptop with a Pentium N3540 processor, 4GB ram, and a 500 GB hard drive.
It was running Win10.
I have the computer here in my office.
She told me that while she was using it last week, a message popped up that said that unless she sent $300 right away, the laptop would be disabled.
When you first turn it on, you get the HP splash-screen and a message that it is "attempting automatic repair."
Then: "diagnosing your PC."
Then an Automatic Repair screen that says: "Your PC did not start correctly."
The options on that screen are "Restart" or "Advanced Options."
If you hit restart you eventually end up at a screen that asks for a password; there was no password on this laptop/
I have not tried the "Advanced Options" choice.
Thanks in advance for any help !
