Question about Compaq Armada M700 Notebook
When the power ON is keyed, the battery charging LED flashes (Even when not connected to mains power) and turns off after few seconds. I've checked the battery, it shows full charge. The laptop was working fine, and was switched off normally the last time. Removing the battery out and re-trying to switch-ON using mains power gives the same result. Request for urgent help and advice from all who have encountered a similar problem.
Had the same problem with My Compaq M700 No Boot Or Post. Battery Light Flashes 8 Times, Have to Wait 24 to 48 hrs sometimes longer to get Laptop to Start. Tryed the DC Converter Board Change No Difference same Problem. Noticed When Laptop Did Start Clock Time Was always a Little Off 2-4 Hours sometimes more. So Figure CMOS Problem With Time Issues. Read About Battery Memory Transitor Voltage spike Detection Issues Corrected With Newer Bios Flash at HP Supports. So I Flashed Bios With Latest 686h. During the First Boot After Reflash Battery LED Did flash No Start, After pushing the power button again it Started. And has Every since.So Far Laptop Now Boots Everytime and CMOS Checksum Seems To Keep Time Correct In Windows. The Bios Flash Corrects a Voltage Spike Detecting Transistor In The Charging Circuit. During First Start after flash Bios will run system test on the charging system and Correct CMOS. Worked for Me Hope this Helps a Few.

Further to my post of December 20th. I bought a 'for spares M700' which had a working motherboard and display.
From this I was able to isolate the problem to the dc-dc converter board - a well knpwn weak point.
I have seen posts that say that replacing the dc-dc conveter board did not solve it. I can only think the replacement was faulty too.
Hope this helps a few people with the 8 flashes fault.

Replace the power plug. Often the solder joints become bad on these models.
