Why is my m6300 not booting up? I installed a new cover and HDD and the screen is blank when I power up. There is a beep and nothing. I removed the BIOS battery and placed it in the new cover before installing it. I do not have any disks. Thanks in advance for any and all assistance.

I think so, because when it tries to post aznd finds no ram you will get beep code

Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

remove the hdd and power on.
after that you can see some different massege like as no hdd installed, no operating system, or
trying to boot via nic, etch.
if can see you nrrd to repleace the hdd.

Two beeps usually means the memory module went bad.
Replace it and you should be ok
Good Luck.

Dont forget to rate this answer if it helps

you can not expect it to boot up from a blank hard drive
so you will have to go into the bios settings and change boot preference to cd or usb stck as first preference
you will then have to buy an operating system on a disc or win 10 on a usb stick so that it can boot up from that

Did it display any video at all with boot options or HP logo? Any POST test or beeps after you started the laptop?
Try removing the power ac adapter and battery. then only boot it up with just the AC adapter (no battery).
Good Luck, JAJ

there is a lot of factor for a death pc. ignore it all. just check the following :
1. is the hdd led flashing
2. remove the cpu cab and make sure that the fans are spining for both smps and processor
3. any un usual beeps at startup
4. any onscreen message or a blank screen
5. and bla bla ... ...
so far, let's fix it
1. check power and signal connectors of hdd or replace new .
2. re connect all the power connectors on the mobo or change a new smps
3. de assemble, clean and re assemble all the parts inside if there is any unusual beeps
good luck

Hi,

Things to Check When No boot...
1. Have you connected all the power cable?
2. Do you see any display?(including the power lights glowing)
3. Does the screen show you any blue screen error message?
4. Do you hear any beep noises?
5. Have you tried to install any third party hardware or software?
6. What do you think could have caused the issue?

The beeps are beep codes. Were they short or long? Also do you know who makes your BIOS?
