Hi
In October I bought the Inspiron 7720. After 4 months, the laptop wouldn't boot immediately anymore. I had to press CTRL+ALT+DEL so it would retry.
It always worked the second time until yesterday. Now it doesn't boot at all.
I've found a lot of people here with the same problem. My OS is Windows 8.
A lot of solutions are proposed but none of them work for me.
Tried solutions:
1) reset BIOS to default configurations (doesn't work: access denied)
2) disable secure boot
3) change from AHCI to ATA and back
4) ran system diagnostics: no errors
5) pulled the battery out and tried with only AC
6) pressed power button for 15sec without battery/adapter
7) rebooted 3-4 times with (only AC) to get the windows recovery screen (didn't work?)
Nothing at hardware level has been changed since I bought it.
Any help please?
Thanks in advance!
