Question Laptop boots only sometimes at random

[jozinovitko]

Hey! I have a weird issue. My Samsung 350V5C-S05CZ boots only sometimes. Like one of 10 times when I turn it on. Sometimes it boots 2times in a row and sometimes it doesn´t boot even after 20th time. When it doesn´t boot Leds turn on, fan is working, but screen remains black. It seems like sometimes the power on self test just diagnoses something wrong and notebook remains in this state (it is exactly like when you don´t have any RAM connected). I don´t think any hardware is damaged, when notebook boots it is working completely fine even for hours, booting is the only problem. I was thinking about updating BIOS, can it fix the issue? Is updating BIOS safe? Thanks for your replies!

Hello there,

I know that it is not nice to redirect to other sites, but try reading this:

Samsung 350v5c does not boot

Hi there, my laptop will not boot. I press the power button, light comes on. Fan will start. It does not appear to do a POST. Screen stays absolutely black. I cannot get into the BIOS. There is no output from the HDMI so I am assuming the screen is OK. I have swapped the memory about and it...

And from my own experience this might be the issue with a graphics card. As I had an Dell laptop which required GPU pre-heating. Also check you RAM, try to push it in. Maybe they got a bit lose or something. I'm not sure about BIOS update, tho.

Hey! Thanks for your reply. I know about GPU issues, but when I actually boot ntb is working completely fine for hours, no signs of bad graphics. Checked and switched my RAM a lot of times. Tried other two RAMs too. Nothing really helped with the problem :/
