I installed new VG224 is not boot properly . it gives beep sound ?

The reason with your laptop does not boot is power chord does not plug in...memory problem...operating system and corrupted hdd...
Check the power chord if properly plug to the outlet Check the memory if you heard 3 beep or 8 beep...if you hear 3 beep...the memory is not installed properly...check and install properly...if you hear 8 beep you need to replace the memory with new one...if you hear a continuous beep...the memory...discard the memory...open the laptop then off immediately...then install the memory again...
if the problem still exist...

Please go to the nearest repair center to fix the problem. Because it is very fatal and need assistance from a technician

Remove the RAM and install it again and restart.....it will work if still not work then change remove RAM again and start your machine..it will give beep sound...if it will not give beep sound then understand your machine's mother board is faulty......

this beep is possibly telling you your hard drive is having an issue.
the boot sector is probably gone and you will need to format the drive, or buy a new one and install it.
Please give detailed information as to your issue to better assist you in your resolution of the problem you are having.The more information given will help determine the resolution and guide you to the proper fix for your issue.
Thank you.

The three beeps tells you that something inside the system is not properly installed. Check all hardware installations and position properly all hardware not properly installed. If nothing is improperly installed, try cleaning the RAM with a piece of clean cloth and install properly.

the beep pre-boot is signaling a kernel panic. It could be bad ram or something else, it's hard to tell without hearing the beep (they signify different things)
1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable

So depending on the beep, it means different things. However in any case I'd suggest taking it to an Apple Authorized Repair Facility. Unless you feel comfortable with assessing the proper solution on your own
Good Luck.

make sure the ram is properly installed just remove ram and check it give the beeps if it gives the beep that means board is ok clean the ram with pencil eraser and fix it again.

Have a nice day and do not forget to rate please...!

Here is a list computer beeps and what they mean.

• No Beeps: Short, No power, Bad CPU/MB, Loose Peripherals
• One Beep: Everything is normal and Computer POSTed fine
• Two Beeps: POST/CMOS Error
• One Long Beep, One Short Beep: Motherboard Problem

• One Long Beep, Two Short Beeps: Video Problem
• One Long Beep, Three Short Beeps: Video Problem
• Three Long Beeps: Keyboard Error
• Repeated Long Beeps: Memory Error
• Continuous Hi-Lo Beeps: CPU Overheating
  

Most times the beeping is caused by a bad/loose connection somewhere or card not seated properly.
Try disconnecting and reconnecting everything again. Make sure that all the power plugs are connected properly even if you didn't mess with them. Moving things around can sometimes be enough to give you the "BEEPS". ";-}


If you are still having much beeping and no computing you can try my personal favorite.

Start first with verbal threats. Next move to a second floor window and, while you explain whats going to happen if it doesn't knock it off, open the window.

If that fails give it the pitch.
Believe it or not I have used this technique and after reassembly and repair.....No more beep.

I hope this helps but if not let me know and we will try something else.

DEAR,

PL SEND INFORMATION OF BEEPS SOUND.
HOW CAN BEEP GENERATE .CONTINUOUS OR ONE BY ONE AND HOW TIMES.

IF U ARE GOING TO HP SITE CUSTOMER SUPPORT THAT GIVES PROPER SOLUTION FOR THAT.

remove the memory chip and try

could you check that the time is correct when you next boot up, as sometimes a beep on startup can indicate a cmos problem, as you may have a flat cmos battery on the motherboard, and the system will keep losing the saved settings.
