@@zilicontech Hi! The problem is back on a next day(( Because the root of the problem wasn't founded. How do you think, could the reason be an old cmos battery? I already tried to run without SSD and memory, the result is the same - so i think the reason is not in these things
@@HeraseemAndMumu what's the number of capslock blink
Mine is 5 blinks
I get two blinks from caps please help
Good job
this comment meant so much to me.
thank you
I hope you'll find more videos helpful
In my case plug out the battery and cmos its worked.but after restart same problem please reply soon
Repeat the process. Hold out the CMOS battery.
Use power adapter only during test, don't insert the battery yet
What if the caplock is not blinking but it's constant
Constant capslock shows that the PC is working, no blink error. to confirm this to be true, tap on the capslock, the light should turn on and off.
If the above turns out to be true, troubleshooting will reveal the cause of the problem. but it will definitely be one of the following:
1. screen
2. display cable
3. unit responsible for display on the MOBO
@@zilicontech the caplocks in on and off it's constant bro
@@EngrMk256 with tap or without tap
@@zilicontech without any tap bro
@@EngrMk256 there should miniseconds between each blink. that is 1 blink and continuous. the PC CPU is not functional.
the cooling fan should be at top speed.
You must have tried the CMOS reset, if it doesn't resolve the problem, look for a capable technician that can handle it for you.
the problem is simply the CPU voltage is not being generated so as to be operational.
