Random startups ?

[blur37]

So i have a dell laptop , N4050 ( heard some bad reviews) so i brought it to a lil traveling and hit it by accident slowly ( like 1 cm drop) and it broke , cant turn it on , it randomly goes on when i shake it ... I tested this with my Netbook , and it survived , and works flawlessly , any help ???

Either a disconnected switch or connector on the motherboard, or damaged HDD. If you are not handy with opening laptops, best would be to let a repair shop take care of it (esp. if first case scenario is the correct one).

Fix ? That service center is mental , i fixed this laptop about 8 times and every fix , new problem always occur .
Seems weird, thats certified center

How old is the HDD? Is it still the original one and more than a couple years old? If so, you might want to try to put in a new HDD (or just borrow one for testing).
If that shop opened the case recently it may as well be they failed to secure some connection when they put it back together.

They replaced hdd like last year with toshiba hdd , they replaced heatsink too , but when i say there is keyboard failure , seems they ignore , same keyboard same problem ... Is the keyboard the source of trouble i mean i press random keys and the laptop boot up then died . Keyboard failure?

Water damage or something similar?

Water damage or something similar?

When it happens my hand was dry , and if for a clue , every 4 hour the laptop starts giving 90% ram load , very laggy and forces me to force shutdown by the power button. I never spill anything on my laptop. Is it worth to try to boot via external usb with windows preinstalled and harddisk For data ?

I meant, water damage (or any other fluids) in the past with the laptop?

Remeber few last use it have a cpu beep code warning , but after i reboot it its gone , could the cpu be loose ?

like I said before, some connection could be loose, esp. inside a system that has been opened a few times in the past.
You have 2 options: either open it up and check it yourself, or get a repair shop to do it. Otherwise we're just chasing ghosts here, nobody can diagnose it 100% from the information available on this thread.
Good luck with the repair and let us know what was the exact issue when you get it fixed.

Ok , tilt my laptop to the right , it boots up well ... When on flat surface and left tilt it fucks off
. Well if this could give some clue-ish i would just mention it

So what happened is the power-in cable in the motherboard is loose , (thanks for making some of my screws lost dell service) so , i complete re-insert all stuffs (excluding cpu and ram) and it works as normal , but my amd radeon hd 7450m crashes on max performance ... Fantastic
