This is a long shot. No promises. Have you tried it with the charger plugged in? You could also take out the battery and leave for a day and then try with just charger. Does anything happens, lights, etc.?

Two things (though you didn’t give current specifications): *Install SSD drive either by replacing current drive or installing drive in the DVD compartment using a Laptop Hard Drive Mount for ODD (Optical Disk Drive) case. *Upgrade RAM. *Make sure Windows 10 and all drivers are updated. That’s about it. There are other Windows tune-ups that can done but just look those up on the web.

Some parts would be close to liquid or on fire so the sensor must be malfunctioning.

Click on “Advanced options” from the “Automatic Repair” screen Then click on “Troubleshoot” Then in Troubleshoot screen click on “Advanced Options” From that screen click on “Startup Repair”, which may take awhile This should fix the problem. If not repeat it again. Sometimes it will say that it hasn’t fixed it but actually has. Try just starting up as usual. Let us know how it goes.

Files should be safe. Will need to take drive out and connect to an external USB drive interface or connect in a desktop computer. Do you know that the SD is functioning properly. Your problem may be due to over heating caused by accumulated dust. If it starts again after a cooling down period then I would suggest unplugging, taking out battery and openning up and blowing out dust with some “canned air”.

Different solutions, purity grades, concentrations, and alcohol types yield beneficial cleaning and disinfection properties when applied correctly; or dangerous consequences when used improperly. This post will help you identify key uses, best practices, and proper disinfection with isopropyl alcohol. Likewise you can see our other posts on IPA as a universal cleaner and the importance of high-quality USP IPA. Why Is 70% the Most Effective Concentration of IPA for Disinfection?: Isopropyl alcohol, particularly in solutions between 60% and 90% alcohol with 10 – 40% purified water, is rapidly antimicrobial against bacteria, fungi, and viruses. Once alcohol concentrations drop below 50%, usefulness for disinfection drops sharply. Notably, higher...

With an SSD you should be booting in around 30 seconds or less. Something is not loading properly during bootup. Probably a corrupted file/program that causes looping (as Windows repeatedly tries to load it until it finally gives up) but which is not essential for operation of Windows so all is fine once booted. Try something like Ccleaner which has an option to disable Startup programs. Disable, NOT delete, one at a time until you find the culprit.
