"Reinstall win 10"


          

At one time I saw a link to reinstall win 10 while keeping all user files. Can someone post this link.
I am working on an HP laptop that must have been hit with a virus since I find a lot of the drivers are stopped. This shows during the boot cycle, the screen goes Black while on external power. If I remove the external power everything works fine until I try and reinstall the external power. If I do it before the disk drive has completed all the initial 'stuff', the screen again goes black.

I'm thinking a clean install is required.

Any thoughts?
Regards,

Dan K

Does it boot all the way? Are you able to do anything in Windows?

If so, try Settings > Update & Security > Recovery > Reset This PC.

Otherwise you should probably connect the drive to another computer and try to copy off the user data, then put the drive back in the original computer and do a clean install from external media.

The problem you describe with the power supply sounds like a hardware problem to me, not corruption or infection. My guess is that the power supply is bad.

I found the HP Restore Manager and did a reinstall of win 10. It did not fix the problem. This is an HP T15.
Here is the situation. If I start the laptop with the external power applied, after the HP logo completes the screen goes black. It appears like the LCD backlight turns Off. If I remove the external Power all is good. Replacing the external power again shuts Off the backlight.
If I insert the external power with the backlight Off, press the Power button once, the laptop goes into sleep mode. Pressing the Power button again, the laptop displays the last page I was on and all is good.
I have set the controls to never go to sleep or turn off the display while plugged in.
I ran the HP Support Assistant and it did not find any out of date drivers.
I am at a loss, any suggestions?
Regards,

Dan K

Try to find another power supply that you can test with. If you can't find an identical one, you need to at least make sure the output voltage is the same and the max output current is the same or higher. Of course the plug that connects to the laptop needs to be the same too.

If the problem remains when you connect the other power supply, then the mainboard in the laptop is probably bad.

I checked the output voltage of the supply and it is 19.5 volts. Using the installed HP battery checker, it shows a good battery at 100%.
New information. If I power ON from total shut down, the HP logo appears during boot. The screen goes Black. If I press the Power button the laptop goes into Sleep. I can see the Power light on the left front blinking. I am pretty sure this means it is in sleep mode. Pressing the Power button again the normal splash screen immediately appears and I can proceed to log on with normal operation.

I have pressed the power button for 15 seconds with the battery and external power removed. I reinstalled the BIOS. I also reinstalled win10 from MS. No new hardware has been installed. The OJ5740 printer driver was installed.
Since this is out of warrantee, if the problem can not be resolved I'll instruct the user on my power button procedure.

Any suggestions?
Regards,

Dan K

I have had trouble with windows 10 with long shut down times. I have a desktop not a laptop but apparently Win 10 saves hibernation files on shutdown weather you use it or not. If I shut down with shift pressed the computer shuts down almost immediately. I don't know if this is related to your problem or not. I believe hibernation files are easily corrupted and hibernation can cause more trouble than it is worth at times. Try shutting down with shift pressed and see if the laptop operates properly and reliably. Just a thought.

I posted this question on the HP forum and they suggested all the things I already had performed.
One suggestion they had was to re-install the BIOS. I had already done that but they gave a link to another site.
Installing this version of the BIOS fixed the problem. In all the years I have been doing repairs, this is the first BIOS corruption I have run into.
During the re-install of Win 10 an application native to the HP laptop was their version of Resource Manager. That did not get re-installed. I have asked HP if it is possible to get a link to this app since I have been unable to locate one on their site.
Does anyone know where this HP particular app can be found?

I found two places that had the sp45602.exe file which was supposed to be the HP Recovery Manager. Both locations downloaded a file which when executed did nothing.
I updated all the drivers and will return the PC to the owner. I don't think they will ever use the features of this application.

Now onto my son's laptop on another post.

Thanks for all the feedback and suggestions.

Regards,

Dan K
