Just got this thing and hasn't started yet. hit power button and the lights will flash, the cd rom will engage and then everything quits and repeats between 2 and 4 times before it stops even trying. The screen never even flickers. No cd in drive, tried with and with-out battery in. Any ideas?

Re: pavillion ze4805us no start-up
Yes, your best option is to call the manufacturers help and support so you will have documentation that it has not worked since you bought it. If they cannot fix it over the web, then you have a record of that also. Then pack it up and send it back for a replacement or a refund..what is happening should never happen and you'll probably always have problems with it. Do not open it and play with it as you will lose your warranty.

DCD or CD stuck, exploded? In the Start Menu, Computer, right click the DVD/CD rom drive , scroll down, click on Eject. There may be a "pin-hole" on the face by the button, you can use a paperclip to insert and open. If All else fails remove the DVD and remove cover.
I had this with a laptop recently. It could be one of three things, the first is the charger, which was my problem. The second is the battery. The third is the charging circuit which is also the most expensive to repair.
Please take a moment to rate my solution.

This is a sample of what you can try to do to diagnose a non-starting computer, If these don’t work, realize that most likely a system board (motherboard) has failed or the actual power trim strip above the keyboard has failed.
Unplug the computer, then take the battery out, push the power button and hold it for about 30 seconds. Plug the system back in (leave battery out) and push the power button. If it starts, Great! If not unplug go to the next step.
You should still have the battery out and the power unplugged. Now turn the laptop over. Take off all the covers and pull out the hard drive and ram and wireless card. Find the screw that has a symbol kind of like this � its the CD rom drive screw. Now pull the drive out. Pick one stick of ram and put it back in the computer. Flip it over open it plug it in and hit the power button. If it does not fire up then unplug it and switch the ram. Plug it back in and hit the power button again. If it doesn't start up, unplug the computer and go to the last step.
Pull the memory out and find the screws that hold the keyboard on. There are symbols in the plastic there should be 2 screws holding it in. Now in the battery compartment, there are several screw at the back edge of the computer take them out and also the ones in the battery in the center strip. Some are silver and some are black. Once you have the screws out of the battery area flip the computer over and open the lid. The strip just below the LCD with the power button and controls will now be able to be lifted up. You will probably have to lightly get an edge started before it will come up. There should be several little cables hooked to it. Flip the control panel over and look for some screws holding the keyboard in. I think there's 2. Lift up the keyboard. Making sure there's nothing touching anything important and then plug the computer in. Carefully hit the power button and see if the computer tries to start. If it does try it will probably beep at you. Unplug it and put a stick of ram in it. Plug it in and try to start it again. If not, unplug the computer and Go to the next step.
Carefully put the keyboard and control strip in place. Flip the computer over and loosen all the screws that hold the computer together. Flip the computer over again and pull the keyboard and control strip up again. Flex the inner aluminum plate that was under the keyboard lightly. Plug in the computer and then hit the power button. If it tries to start, Great! put it together again in the reverse process.
If it does not, there are 2 possible things I would suspect the Control strip or the mainboard. If you don't get the computer to start back up please put it back together so you remember where all the screws go. Even if you plan to get another mainboard put it back together.
You got some short on board, You need techguy. Or possible Bios flash, Remove the Harddisk and press the power button.
If nothing change, Remove power, battery, cd rom, Hdd, memory.
Then put one stick of memory, power up, see anything comes up.If does, power off, put the other memory plug in power, fire up.
If does ok. Then plug off, and put hdd without CD rom. see if it did work.
If none is worked as I say you have short or CPU fan is not functioning.
insert the os disc in some cases systems come with a system recovery disc if this is not the case just insert what you have shutdow your system when your system boots press the del,f2,or whatever hotkey your system uses to enter the bios menu then while in bios go to boot devices or boot options and click start from cd and then press f10 to save and exit your system will ask yes no click yes then it should restart and a white text should appear saying boot from disc ? click any button when os finnally loads it will ask you to install or to repair ?click repair this searches your system finds out what it's lacking and reloads it .this should be it hope this helps good luck !!!!
When you insert the power cord are any of the lights? Make sure to remove battery when trying this.
If not, your adapter may be faulty and you can try and measure the voltage coming from your adapter with a multimeter? Put one probe on the inner part of the power cord end that goes in your laptop and the other end on the outer part.
enter the bios setup, if you can boot the computer/laptop. Usually F2 on bootup, it will say entering Setup.
Then scroll through the pages to see if your hard-drive is recognised by the system.
