Laptop in startup repair loop after hibernation

I have been trying to make my Toshiba Qosmio laptop to start without any success.

A bit of history: since I installed Windows 7 in the laptop three years ago, whenever it runs out of battery I can not start it. After pressing the power button, initial Qosmio screen appears followed by a black screen with blinking cursor. It stays here forever. After reading various forums I realized that my computer enters into hibernation and never gets out of it. I found a way to start it by removing the hard drive and installing another one, starting the laptop, letting it run for few minutes, and then installing back the old hard drive. After this when I start the laptop, a blue screen shows up, but after that I could start the laptop normally. This method worked so many times until yesterday.

What happened yesterday: the laptop ran out of battery, and went into hibernation. I did the usual swapping of the hard drives, but this time after the initial Qosmio welcome screen, a blue screen will show up for a bit of a second (I can barely spot it) and then a screen asking me to start the laptop with Startup repair (recommended) or in normal mode. Since I can not start it in normal mode, I chose the startup repair. But the Startup repair can not fix the problems, and can not even detect the problems. I ran the Startup repair several times with no success. Here is the diagnosis:

Problem signature 01: 6.1.7600.26385
Problem signature 02: 6.1.7600.26385
Problem signature 03: unknown
Problem signature 04: 21201020
Problem signature 05: Auto Failover
Problem signature 06: 3 (this number increases with every additional startup repair run)
Problem signature 07: 0xd1
os. version: 6.1.76002.0.0.256.1
Locale ID: 1033

I tried restoring to a previous point, nothing to restore to. Tried the Startup Repair Infinite loop recovery from the command prompt (suggested on this site), didn't work. I can not boot in safe mode. Tried recovery using installation disc, didn't work. Unplugged the cord, removed the battery and pressed the power button for several seconds, nothing changed.

One interesting thing: I tried to mount Linux in order to see the c: drive (needed to search for some files), but Linux doesn't want to mount. It says that windows is in hibernation state and hence, can not mount safely. So it seems that the laptop is still in hibernation and can not get out of it.

I did a back up of almost all of my files, except for several of them that I can not locate. I hesitate to do clean installation of Windows 7, I don't want to lose those files. Any ideas what to do to make the laptop run, get out of hibernation state?

Work through these steps to try everything possible for Troubleshooting Windows 7 Failure to Start
which leads up to if necessary rescuiing your files to get a perfect clean reinstall of Win7.

We will then troubleshoot the hibernate feature which is often dependent upon the latest display adapter. So be sure to follow the steps for correctly handling drivers in Win7 if you choose to Clean Reinstall.

Thanks for your reply.
I tried to turn off the hibernation by typing the powercfg -h off in the command prompt, but the command is not recognized. Tried several versions of the command (powercfg.exe/hibernation off, powercfg/hibernation off, the above one) nothing. Too bad I was hoping that would help, and make my life easier.
Right now I am running the Windows defender offline. The quick scan didn't find any malware, so I started the full scan. If that doesn't find anything, I will proceed with other malware removal tools as suggested in the Troubleshooting Windows 7 Failure to start.

Slartybart I can access the command prompt only through the Startup Recovery screen, i.e. when it finishes its scan and the link to Advanced options for recovery and support (which contains Restore to previous point, Image recovery, Command Prompt, Memory diagnostic) shows up. Maybe that's why it can not find the powercfg; or it is, as you commented, the malware. I will know more when the Windows defender scan finishes.

Keep us posted on each step's results as there may be other steps indicated.

I didn't read this entire thread but i have a laptop here that did weird some weird stuff and it was because of a bad battery the chip in battery was bad, It wouldn't load programs at boot half of the time all random it totally freak out never shut down correctly had all kinds of weird problems, Took the battery out and it has ran perfect ever since! I still haven't got a battery for it as its old and i could buy a new laptop before i could replace the battery it was a toshiba.

After reading the thread i would fdisk the mbr and start fresh install complete full format, Viruses can get in the mbr and reinstalling will not help you with a plain format, They can also attach to the network adapter or get in the bios of the computer, If it is none of that then it is a hardware issue somewhere. You should be able to force resume hibernation to fail then it should try to boot normally. Check your bios options also.
