While these steps may not be the answer they are the first steps in diagnosing the problem and eliminating possible causes. One question. Have you ever torn down a laptop before? What is the laptop telling you? anything? Status Light Indicators: The status indicators help identify the current hardware status of your Notebook PC. (1) Power indicator lights up when the Notebook is turned on and blinks slowly when the Notebook PC is in sleep mode. (2) Two-colour battery charge indicator Solid Green = Notebook charger is plugged in and the battery power is between 95% and 100%. Solid Orange  = Notebook charger is plugged in charging its battery and the battery power is less than 95%. Blinking Orange  = Notebook is running only on the battery and the battery power is less than 10%. Lights off  =  Notebook is running only on the battery and the battery power is between 10% to 100%. (1) Drive activity indicator lights up when your Notebook is accessing the internal storage drives. (2) Airplane mode indicator...

I don’t know the service shop you went to but if it was me I would try taking out all accesory devices - SSD/HD, RAM, Optical drive, Wi-Fi card, battery, etc. Remember a fault or short in one of them could put the whole main board off. Here is the link to the Service Manual: http://h10032.www1.hp.com/ctg/Manual/c06... Then with battery out and power supply/adapter connected try one RAM module at a time and try to start up. Anything? If nothing I guess the mainboard is defective. If yes can you get into the BIOS/UEFI and run the built in HP Diagnostics as so: (1) Turn on the computer. (2) Immediately press the f2 key repeatedly, about once every second, until the UEFI menu opens. (3) When the UEFI menu opens, select the diagnostic test you want to run, and then follow the on-screen instructions. If that passes the test hen try booting off of a bootable USB drive. Did it work? Yes? Then add the main drive and see if it boots up. No? Then drive is defective or corrupted. Good luck my friend.

Type ''BOOTREC /FIXMBR ''and hit <Enter>. This command will attempt to fix any corruption issues with the master boot record. If all goes well, you should see The operation completed successfully. Next, type BOOTREC /FIXBOOT then hit <Enter>. This command will attempt to write a new boot sector on the hard disk if Windows detects damage. Usually, this happens in cases where an older version of Windows was installed, or a non-compatible operating system such as Linux was installed. If you are seeing an error such as Boot Manager is Missing, then the BOOTREC /RebuildBcd command might be able to fix it. This operation can also restore boot entries for older versions of Windows if you have a dual boot configuration. If BOOTREC /RebuildBcd does not work, then Microsoft recommends you back up your BCD (Boot Configuration Data) store, then run the BOOTREC /RebuildBcd command again. Here is how you do it. Type each command then hit <Enter>: ·                     bcdedit /export C:\BCD_Backup ·                    ...

This is not so much an answer but rather a possible pathway to try. Data recovery can be very complex. The "RAW" problem can be corrupted partitions and/or filesystems. You will most likely need a professional data recover program. I've mainly used freeware Testdisk, which you mentioned, and Active, which will cost you. It is your choice. Here is Active's url: https://www.lsoft.net/bootdisk/ That’s the full package partitions and file recovery. You can try the freeware evaluation version. They also have a freeware program which could initially help you get a better idea of what's what:https://www.lsoft.net/ntfs-recovery/ Sorry but I don't think there is a simple solution here. It looks like the Dell website SupportAssist really mangled things. For myself, for sport, I try all kinds of little tweaks but for clients I just do the data file recovery. After files are recovered you can always fiddle around with the partitions, etc. if you are curious. I once used EaseUS to convert GPT to MBR partition and then...

It is always dhelpful to explain clearly exactly what you actually did and how you did it. For eample, were you trying to install Linux from within Windows??? Did you back up your data files, etc.? Do you want to get Windows running again? If so the first thing you can try is booting into the Windows recovery environment, if possible, and then performing a start-up repair. To access the recovery environment, turn your computer on and off three times.  While booting, make sure you turn off the computer when you see the Windows logo. After the third time, Windows 10 will boot into diagnostics mode. Click Advanced options when the recovery screen appears. Click Troubleshoot.  Click Advanced options.  Then, click Start-up Repair If this is not the case then just make a Kali Linux bootable USB drive and do a clean install of Linux.

Here’s the LED codes from HP: https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/HP-Laptop-Error-Blink-Codes/td-p/6142972 So as you will see you have to count the blinks. (1) First column for the number of blinks. (2) Second column for location. (3) Third for component being checked (4) Fourth for error condition. What is your resul?

Just follow the guide: Xbox One Repair so you get some direct experience.

Having a second look at your original question it does seem like like a software issue because it would be quite a coincident for hardware to fail after just an update. Have you tried getting into the UEFI (BIOS)? To load the UEFI firmware settings menu: 1. )Shut down your Surface. 2. )Press and hold the volume-up button on your Surface and at the same time, press and release the power button. 3.) When you see the Surface logo, release the volume-up button. The UEFI menu will display within a few seconds. This will show that your hardware is probably O.K. Another thing to try is booting Windows from a USB drive as follows: Note: Before you start, make sure you don’t have any other USB devices connected to your Surface, including USB mouse devices, keyboards, or other storage drives. Surface will try to boot from any other connected USB devices. 1.) Shut down your Surface. 2.) Insert the bootable USB drive into the USB port on your Surface. For info about how to create a bootable USB drive for your Surface,...

You could try removing as many components as possible, one at a time, to check for electrical shorts, etc. (1) Remove hard drive. Now can you get to BIOS screen? If yes then that is your problem. (2) Remove both RAM modules and try each one, one at a time, in both sockets (3) Repeat with WiFi card, etc. Have you cleaned out dust and made sure fan is spinning?

These name branded external drives are the worst possible choice. Always, always purchase a SEPERATE case/controller and hard drive. Again, why? Often the branded ones have the drive’s circuit board and the USB port imbedded in the same circuit board. If that circuit screws up you are often lost. The component solution (like a good hi-fi sound systems) allows you to easily take the drive out, if the USB part goes bad, and recover your software in another system or case. If the drive dies replace it or upgrade to SSD or larger capacity. A no brainer!
