Chosen Solution

I have a HP EliteBook Folio 1040 G1 (i7-4650U, 8GB DDR3, 256GB SSD) which was working until last evening. Now, if I plug it in, I get a power button blinking on and off, and the charging port blinking between orange (amber) and blue (turquoise). I bought this laptop from a refurbisher, and it has a non-original battery. I have opened the laptop, unplugged the battery and CMOS battery and plugged it back in, to no luck. I have also pressed the power button for a minute, and still get the issue. I am suspecting that the battery is dead. I have learned that unlike other laptops (Dell, Lenovo), HP routes the charging port power through the battery and then the motherboard, and a dead battery on a HP means a non-usable laptop. It can also be a motherboard issue on the HP. Fortunately I have another (slightly newer) laptop (Dell Inspiron 2-in-1) which is use for mostly schoolwork and internship (where the HP is used for non-school/work stuff). Maybe the Dell will become my one and only laptop if the HP fails. I have ordered a new battery (for the HP), but is this problem a battery one or motherboard failure. Or is this issue just that I need to leave the laptop for a few hours. Please help.

Hey, I had the same problem with that laptop. My father dropped the laptop and it started slowly blinking. In my case I did following:

  1. unscrew all the bolts
  2. unpin battery
  3. unpin cmos
  4. hold power
  5. connect cmos
  6. connect battery
  7. run it On some video lady described that in entire board there is too much power and in my lame understanding pushing power without batteries might discharge whatever there was.
