My Toshiba Satellite M50D-A-10V, PART NO PSKPSE-01500VN5 serial
no YD049429P bought May 2014, will only boot occasionally and
this problem is getting worse and worse. Problem began in January,
with frozen cursor (keyboard is functioning).

A failed reboot is like this: black screen and white and amber
LED is turned on. Seems like it's more likely to load Windows
when the battery level is half-empty, but I can't tell exactly.
Is it a loop somewhere in the hardware-programs, that prevents
the laptop to boot 350 times (approx.), and then allows one? I
have powered up all day, every 5th minute or so, and all I achieve
is max 3 successful bootups. It's been like this for weeks. The

error with a frozen cursor still apperas now and then, otherwise

I could have kept the lapton on all the time. But to get the normal

cursor back, I must reboot.

The following troubleshooting is performed:
Replaced hard disk, tested memory cards (reset), taken out the
battery, held down Power-button for 30 sek after battery removal,
a clean install of Windows 8.1 from disk partition delivered by
Toshiba, from Recovery USB and the Recovery Environment.
Performed StartUp Repair from Recovery Environment (USB),

but all these efforts made no difference.

What does these symptoms tell a hardware expert: is it a single
hardware component responsible for this, that can be replaced, or
is it some vague error on the motherboard. I want to know if a
small part can be replaced, so the problem is fixed for a small
amount of money. The small battery inside is not removable, but
connected with metal threads. These threads will break if I remove
the tiny battery.

I doubt that installing Windows 10 will solve the problem. Because
I have just performed a clean install, and now it's like the
laptop was right from the shop.

 

What does this tell a hardware expert? Is it worth taking the laptop to a workshop

for repair, or should I replace the motherboard myself.

if you have already replaced the hard drive, my bet would be on the motherboard, and it would be a very heavy bet
