Windows 10 - How to go to Control Panel
Open 'My Computer', 'Computer', or 'File Explorer'
One of the common problems with older Laptop and Notebook are about Battery Charging - the Battery are Not Charge up at all anymore. The reason could be a broken power connector on the back/side of the Laptop / Netbook. Take a look and see if it looks like it's been damaged, perhaps a pin Missing, Broken or Bent. Thought it is tedious, which requires dismantling of entire Notebook or Laptop, this repair is quite common and straightforward.

Repairing a laptop normally more economical than buying a new one, for a start it's probably got all your important photos, music, documents etc - so by changing the LCD / LED screen you are very unlikely to loose any of that data.
Here is how to recover your files:
The ransomware function this way :
When a user launch it (usually by email) it will encrypt all their files and add in each directory a document explaining that they will have to pay in Bitcoin 500$ to recover their files.
FYI, if you pay, you will actually recover your files, but is there another solution than paying 500 or 1000$ to some kind of mafia ? Yes.
Power-Off the machine : the faster the better
CryptoWall operate this way :
First it will do a copy of your original file, and encrypt it with what they claim to be a RSA2048 key. Then it will delete the original files. It goes on until it encrypted all files on all disks and network shares the user can access.
In a second time it will try to delete any windows shadowcopies of your files to prevent you to recover a previous "unencrypted" version of your files.
The reason you should power off the machine quickly is that it might prevent the suppression of shadowcopies. Then all you have to do is power on the machine, press F8, launch it in Safe mode, and use antimalware programs to clean the virus. then use the "precedent version" tab on properties of your user folders to recover unencrypted files.
What if you have no shadow copies and no backup of your files ? There is still a way.
As I said, Cryptowall doesn't encrypt your original files. It will do a copy of it, encrypt it, and delete the original file.
As you probably know, a deleted file can be recover if nothing as been written over it on your disk. Good think you quickly power off the machine soon after the infection !
Now all you have to do is take your hard drive out, put it in another machine as external drive, or second drive if you don't have a sata dock, an run a file recovery program.
I use Ontrack EasyRecovery or R-Studio, or even DataRescue for Mac.
The pro version of Ontrack EasyRecovery might also be able to recover files from a RAID array if one of your network share as been encrypted and you don't have backups.
All these programs will be able to recover the original files deleted by Cryptowall.
Just make sure when you run those to NOT do it directly on the original machine as by writing on your infected disk, the program could Overwrite your deleted files.
You should be able to recover 99% of your files using this method.
After you recover your files, always do a clean format / install of your machine.
Of course the best way to protect you from this kind of virus is always the same :
Have a backup. Always. And a good up to date AV.
