My evo n610c wont power on the led orange keeps blinking

sounds like your DC coonector came loose from the system board.it is a common problem with laptops,

Problem symptoms:

1. Laptop randomly shuts down without any warning.
2. Power LED and battery charge LED start flickering when you wiggle the power cord or the AC adapter tip on the back or your laptop.
3. The battery will not get charged.
4. When you plug AC adapter, the laptop appears to be dead and there is no LED activity at all (DC-IN jack on the system board is broken).

here is how to repair:

Since you tried your battery on another pc, then try a different charge power supply on yours. You may have a bad power supply adapter or your battery terminals on your pc may be dirty and need to be cleaned with rubbing alcohol and a cotton swab.

Try this link, refers to the n600c more than the 610, but that is the exact same battery so it is the right info:

I have compaq Evo N610c, which would not start when i press the power button, & when i press the power button or slide reset button the battery led blinks umber 8 times and then green 1 times of the HDD led.what should i do, would you please help me, thank you//

When you plug the laptop to the power adapter, you should see the indicator led lit up telling that it has good connection to the ac adaptor. It wont turn on because either there is a loose connection to the power adaptor and hasn't been charging the battery, or the power adaptor itself is bad. Check the power plug with a miltimeter, it should be around 19 Volts.

pls connected to pc to mobile phone bluetooth connected

It is a known fault with the speakers - obtain a replacement set but be aware though the panel is easy to lift the plugging in of the cables into the m/board requires some dexterity.part number from hp,
241438-001 Switch cover - Plastic panel above keyboard that houses the LEDs, power switch, and Internet buttons plus speakers

Remove your battery - start the unit on A/C then after booting up refitted battery.

cheak the all battery points.

The computer's power light may blink to indicate that there's a problem with the power from the AC adapter.
