Symptom recap and first actions: reported the AC adapter powers the machine long enough for the power LEDs to flash on/off but nothing appears on-screen — a common startup pattern with several possible roots. Start with basic power checks: verify the wall outlet and adapter, remove the main battery (if removable), disconnect the AC, then perform a power (hard) reset by holding the power button for ~15 seconds to drain residual charge; then reconnect AC (leave battery out) and attempt to power on. This reset sequence is the standard first step documented by HP. ()

RTC/CMOS clearing and what others found: reported success by removing the RTC (CMOS) battery for a short period. The Armada M700 maintenance guide documents clearing CMOS/BIOS by removing AC and the main battery, disconnecting the RTC battery cable (via the modem/combo card access), waiting several minutes, then reconnecting — a safe diagnostic to try before replacing parts, provided ESD and disassembly cautions are followed. (manualslib.com)

Is it the display or the system? suggested the inverter — valid for cases where the unit seems to power but shows no visible image. Distinguish display faults from a failed POST by listening for fans/HDD activity and by connecting an external monitor. If an external display works, or a faint image is visible with a flashlight, the backlight/inverter or display cable/panel is likely at fault; check the lid‑close switch and reseat the display cable before buying parts. Practical inverter/backlight tests and lid‑switch checks are described in laptop-repair guides, and HP guidance recommends the external‑monitor check to isolate display vs motherboard faults.

Further steps and when to stop: reseat RAM and the hard drive, try booting with battery removed, check the DC jack and adapter with a multimeter or known-good adapter, and record any LED blink patterns (the service manual’s POST/LED tables map blink patterns to likely failures). If none of the above changes the behavior, the fault is increasingly likely to be the display assembly or mainboard and professional repair or sourcing M700-specific parts (using the model/serial from the bottom label) should be considered.

I could not quite understand what you are trying to say. Are you saying when you plug in the ac adapter to the power supply? Also is it when you turn on the computer does nothing come on the screen? I think more people may be able to help you if you explain your problem a little more.

I just resurrected my Armada M700 by removing the RTC (CMOS) battery for about 10 minutes and reinserting it. Before when pushing the on button, only the battery light would come on and shut off after about 5 seconds. I thought it was a goner.

The RTC battery for the M700 is beside the modem. I got the maintenance and service guide off the internet - here's the link, just save it to your hard drive.

It's very informative and tells you most everything you'd want to know about taking it apart.

Hope this helps some of you.

I have a Compaq Armada M700 may be someone out there has the answer. I has worked perfectly since I bought it back in November 2009, but last monday when I tried to start it up it wouldn't do anything. The closest sign of life came from the battery charge light which flashed twice a few times when I pressed the power button but when that stopped doing that it stopped doing anything! Any ideas on how I can get the darn thing to work again?

The first thing that comes to mind is a bad LCD inverter.
They are not too expensive.
