What I have done:
1.Remove and put back battery and DC adapter, reset the laptop using a reset tiny hole it has on the bottom, press power botton= NOTHING,
2.Remove battery and DC adapter, press and hold the power botton for about a minute, put battery and DC back, press power botton again= NOTHING,
3. Remove and put back the RAM memory and HDD= NOTHING,
4. Try an external CRT monitor=NOTHING
5. Remove and put back the DVD ROM drive=NOTHING
Can someone please, suggest me what the problem might be and how to attempt to fix it?
Thanks in advance,

If you can't even see the POST information on the LCD during booting then I think you machine is truly dead (Hardware failure). Most likely a motherboard failure.

I am thinking it could be the cmos battery. If we don't even get to the bios screen, then it is either mobo or cmos. I am thinking a battery can 're-energize' for a boot up eventually (like putting into the refridge a AA battery). A cmos battery can and does go. 3 yr life span usually. I am going to call tech support but my money is on this -- a pc boots up in a specific order. If you had bad ram, you will get specific beep codes to let you know the problem. If we don't get to even that, then it has to be the first step which is that battery. In a desktop pc, it costs about 25 bucks. Let me know how it goes.

Your DV2225nr problem is likely to be a known HP AMD/Broadcom based motherboard failure issue. See HP official response below:
The cost of sending you laptop to HP is probably not economical (if it is out of warranty).
However, if you are handy with assembling laptop, you can probably buy a used motherboard from EBAY quite cheaply and replaced it yourself.

If I leave the dv6450 laptop connected to the power cord, it works fine BUT after a few hours away from the wall outlet and running on what should be something of a charged battery, once shut down, the laptop won't start. lights flash for just a second and then OFF again. If I put the laptop in the freezer for 15 or so minutes, it will restart.
Question is, if it was the CMOS, wouldn't I lose settings, date etc in the process of it crashing?
PS It is not an AMD motherboard and not part of the recall.

This is not only for you but all who are doing laptop repairing professionally. If a laptop or desktop computer (whatever may be the brand/company) don't display anything and don't produce any beep codes but all other things are OK; before attempting to repair it try the procedure given below.
1) Unplug the ac adapter.
2) Remove the battery.
3) Remove the CMOS battery.
4) Disassemble the unit.
5) Take sharp ended metalic tweezer.
6) Shorten the CMOS battery contact for
a while with the tweezer.
7) Shorten each and every electrolitic
capacitors for a while.
8) Refit the essential parts for a test.
9) Check the wheather the problem has
In some cases it will solve the problem.
