So, after some trail and error and a bunch of troubleshooting, there's something wrong (identified 1, might be more). It is an Acer Aspire 4738G, previously it kept on restart and my dad sent it to a technician and they say the graphics card burned and they changed it to a recon one (honestly i don't know how they did it, it is soldered to the board), so the laptop came back and can be used but cannot plug in with hdmi to a TV.
Two days ago, while my dad's using it, it suddenly blacked out, nothing came up when turned on, similar to my previous post. Surely, i found what happened to my laptop and you guys can see the answer i marked.
So, back to my dad's laptop, the troubleshoots i had done were:
1. Switched dad's laptop hdd to my laptop
My laptop posts, i entered my laptop's bios and found that the hdd is detected, exited bios and continue, nothing happened, hdd light blinked a few seconds and totally gone. Restart my laptop again without entering bios, still same, after post and blank. Hence i can deduce that my dad's laptop hdd is dead.
2. Switched my laptop hdd to dad's laptop
Hoped it works, but it still the same, dad's laptop does not post and nothing came out on screen. Besides, i found out something weird, when i wanted to shut it down by holding the power button, i just need to press the button, no need of holding it, and dad's laptop shut-ed down. My laptop would need to hold down the power button for a few seconds to shut down tho. This not posting and nothing on screen problem is the same as my own laptop (as topic shared above), so i...
3. Changed ram and check ram slots
Can't prove anything either, switching slots, switching rams, still did not show anything on screen. Dad's laptop ram works fine on my own laptop tho.
Attached is the pictures i took about my dad's laptop. There's something bothering me, there's a small metal piece (picture 4 and 5) on the graphics card heat sink. Took more pictures of it because i suspect its the graphics card burned out again but end up more faults found.
So what i wanna ask is that what is actually wrong here, which parts that i can identified as faulty so i can help the technician to narrow the scope down and fix it for me. Or is it really no point to save this laptop anymore?
Thank you for your time reading this, i gladly accept any suggestions.
