Windows 7: HDD not booting Toshiba l770

HDD not booting Toshiba l770

Pretty sure the orange light on the laptop is for the HDD, and it's not turning on, as seen in the vid. Screen is still dark but the PSU seems to work.

Laptop has also been randomly turning on at midnight, possibly because of an update, not sure if relavant but worth noting.

Using Windows 10.

I have an L750 with the same lights as your L770. No, the HDD light is white, and then only when there's disk activity. The only amber LEDs are for the battery (when charging, white when fully charged) and the WiFi (when turned on). See Chapter 2, page 9 in the User manual available here: Satellite L770 (PSK3SC-00R004) Support | Dynabook

^It's the fourth light that's off, so actually I think it is the HDD. Should I just repost to tenforums?

You're not actually getting as far as Windows of any sort. This is a hardware issue, not a Windows one, so it hardly matters which forum you post on.

From your video, I see no sign of the Toshiba splash screen at start up. It look like the bios isn't even getting as far as completing its POST tests.

As it happens, my L750 had exactly that problem 6 months ago. The HDD (its original TOSHIBA MK5065GSXN 500GB) had developed a fault that prevented the bios from starting up. Not only that, but the HDD would prevent ANY machine it was connected to from booting, even when in a usb external enclosure.

OK, so it must be the internal controller of the HDD that was at fault. But here comes the really strange bit - put it in an external USB housing and it is fully functional (read and write) and Chkdsk says it's healthy, BUT....

....if this disk is left connected, even in the USB enclosure, no PC it is connected to can boot from anything, its own HDD or a USB.

But, strangely, after testing it for a while it spontaneously cured itself. In fact, I'm posting this from the L750 with that same HDD back in place.



If you cannot even get as far as the BIOS, then remove the HDD and see if the BIOS then works normally. Try the HDD in a usb enclosure if you have one. See if it can be recognised by another PC. If you are (very) lucky it may just be a temporary glitch (as mine was).

If not, you may have to replace the HDD. If so, I hope you have a system image you can restore to the new drive.

Do you have a healthy battery? Bad battery can make the laptop un boot able.

As @Bree suggested, take the disk out and see if you have a POST.

It can be registered/read on my other PC so it's not the drive, tried putting it back into my laptop but it still wouldn't start. I can't/am not going to put it in a seperate PC because if all the effort plus not having an easy way to do that so... Now what? It can still be read. Doubt it's the battery, the power cable works fine and it still starts with the fans without the battery but never reaches BIOS.

Did you try starting it with the HDD removed? If so, could you enter the BIOS with F2? Or get to the boot selection menu with F12? If that works, can it boot from any bootable usb (such as a Windows install usb) without the HDD present?

If that will boot, then you have isolated the HDD as being the problem. As you can read from it on the other PC, backup your user files while you still can.

If you can't boot or get into the bios with the HDD removed then the problem seems to be in the PC's hardware. It may just need a reset, try removing the battery then press and hold the power button for at least a minute.

If that doesn't revive it, then try removing the cmos battery for a couple of minutes to reset the bios to defaults. If you still have the problem, try a new cmos battery.
