Laptop does not boot after hard drive change?

I bought a new hard drive for my laptop because the old one was over.

Now unfortunately I have the problem that my pc does not boot up, unfortunately I do not even get into bios only the background lighting of the screen goes on and the components start nothing else.

Is the error still there when you test the plate again?
What do you mean by "and start the components?".
Otherwise google times for your laptop model and BIOS, normally you should find it.

When changing the hard drive, other components were disconnected for a short time (cable was in the way, disconnected) and maybe forget to clamp it again?

If there was a separate slot for the hard drive, it is also because the operating system has to be installed first. So CD in, start laptop and boot from the CD so that the operating system is installed.

Unfortunately, I can't instalir as there irrigndwas kaput is us I'm not in the BIOS or the screen does not work and I have tried it with old / new and without a hard drive, nothing has been done

Yes I tried it with old / new and without hard disk did not do anything

As I said, maybe a cable was removed when changing? Or maybe one accidentally slipped out? Then it may be that the monitor is not working anymore. An attempt would be to connect an external monitor.

I have already tried the 2 monitor does not show synonymous

Oh, that sounds like a damage from your expansion now!

Cable checked?

Can you hear startup noise? Starting the hard disk? Fan?

The cable still seems to be stuck in the monitor as well as in the mainboard

and the backlight goes ashore

OK. Indicator lights all on?
Any bleeps?

A beep tone at the start but only with keyboard and otherwise only keyboard stop

Everything else is normal

Did he make the beep otherwise?
If not, Google will beep your device type and beep (short simple, long simple beep, as appropriate). Maybe that gives an indication of what he has
Could possibly indicate a loose contact in the hard disk controller. Maybe this has come off.

Gradually the beep has started to sound long distances, he did not do that before and I was looking for something like that but could not find anything suitable

Have a picture uploaded as a new answer with the beeps

Did you change the hard drive yourself and do you have experience with computers? (Does not mean YouTube tutorials or the like!)

Unless you uncoupled the display contact so that the video card is no longer connected to it, there's probably another lack of contact between your components. Is the Ram in it? Everywhere the power supply?

does your computer show anything when starting, is it just a small thing?

For laptops, the initialization of the components is usually "obfuscated" for the sake of beauty, but the bios can still be removed with it. Or F2 or similar can be accessed.

In order not to get into the bios, you must either have a hardware component damaged or incorrectly connected. Your hard drive may draw a little more power than the old one, and now your complete system will not get enough power anywhere.

I have some experience with computers and basic techniques. I'll see if the power supply is sufficient even if that can't be the fault because the components seem to work normally. The screen stays black only the lights come on and the buttons only make a beep sound when you press them.

Alternatively, you can also try to have NO hard disk in it, so you should, if the error s.der disk is, at least come into bios. And if you come in, the new hard drive is either incompatible or has a defect.

Unfortunately I've already tried this with or without nothing happening with the old one

Is your laptop peeking or displaying any problem via led?

He gives no sound of himself only when I press a button and LEDs has only to show that the power supply is in it and the pc is running

Then only help;

in all parts, which one could have shaken out properly shake, and to see if they are still right in there in the slots.

Otherwise, you seem to have broken something.
