I have a Compaq CQ61-411 Notebook the battery went out the computer was working great but a message came up saying replace battery and it cut off and would not charge back up so it took me a few months to get one so I got one today charged battery for 4 hrs went to turn computer on and the screen is black everything else is power up It's getting power, I put a cd in it and it started turning but is not POSTing at all...nothing on the screen and. The CAPS Lock and Num Lock LED lights are blinking. They blink once and then a long pause then once again...it keeps doing this until I turn it off. What could be the problem like I said it was working fine when the battery went out what could have happened Thanks in advance Mike!

remove the battery and adapter. press power button for 30 sec. then connect the adapter. press power button. if this didnt work. you need to ask for an help of a local tech to check for the video card and cable.

Motherboard. Your best bet is to purchase another computer. If you can however get the motherboard at a cheap price, then go ahead and change it. I would check ebay first.

open up the on screen keyboard in accessories>>ease of access. and then find all the drivers for your keyboard online. AFTER finding them online, then reinstall them.

if this doesnt work i would back up only my files and do a fresh install of windows.

Please search google for hp keyboard problems because there are MANY of them. recently i just had problems with my hp laptop keyboard.

BTW i sent in my laptop to hp and they just changed the keyboard no questions asked so if all else fails or if you dont want to reinstall windows or the drivers just send it to HP.

It would seem that your BIOS has become corrupted somehow. First try entering your BIOS setup. I believe for HP computers when you press power tap the F10 key until it opens. There you can try to reset them in some fashion and save. Try rebooting. If that fails then remove the battery and repeatedly press the power button for about 10 seconds.. (make sure it is also unplugged, this is to discharge the power from the system) then replace the battery and try booting again. Otherwise it would seem that you might have tried to load the wrong BIOS into your laptop. Check with HP then if you are still covered or not. :/
