So I have a "dead" acer aspire 7750g (7750G-2434G75MnkK , i5, radeon hd 6650m) had a corrupted boot sector, and maneged to somehow repair it without losing data and spending money (same hdd 30gb less space) but that wasn't the end, hardweare acceleration didn't work even after deleting and reinstalling drivers with DDU and after a few months green lines showed all over the screen, after reboot no image, but worked with external display ( with the same lines showing up and graphic corruptions on boot). Probably it's because of the HDD, not sure tough, even without it no bios, nothing...

Saw a few videos that showed how by cutting off power to the dedicated graphics I could get it back and running on the igpu, but after removing the choke over the gpu die even the monitor didn't show anything, removing cmos battery didn't help.

 

 

The second laptop is really old, a presario c735el, but i'd like to repair it for some retro gaming and for emotional reasons, a few days ago I just plugged it into mains and the power light blinked (normally it doesen't), it also refused to boot and when plugging the obviously dead battery into it every light (power button, WLAN button, notepad lock ,caps lock ecc.) blinked togheter, there was also a pop sound at every blink.

the psu voltage is normal and I haven't dropped the laptop in ages 

 

Thanks to anyone in advance, sorry if I mispelled something or if I didn't see the trubleshooting section

I think the gpu is burned out. Or maybe the monitor has an issue for the green lines

And the battery on the second one is probably dead as well.

that's obvious,both have dead batteries,but they worked on mains no problem green lines were visible on the last time the screen worked and on the external monitor,but shouldn't it switch to the igpu since the dedicated one isn't getting power? 

 

This is one of the videos  that I saw, from GeForce forums
