Beware non-maker batteries since makers now lock them out due to the battery fires and the liability if they allow non-approved batteries.
But the generic reset noted in this forum's sticky is to remove battery, AC, press and hold the power button for one full minute. If you want to see if the machine is still alive, plug in just the AC and power it up.
I own a HP Compaq CQ-60 Laptop.
Recently the battery life was very short until it got to the point where It could only be unplugged for 3minutes without the laptop turning off, at this time a Battery Alert message would come up when I turn on the laptop.
So i ordered a new laptop battery, it took over a week for my new battery to arrive and in that time my laptop stopped turning on, when I tried to turn it on the 3 lights on the side would flash 3 times but no reaction otherwise from the laptop.
When the new battery arrived I just put it in and plugged in the laptop for 8 hours, then I tried to turn it on and there was no reaction, not even the 3 lights. I tried the old battery in the laptop again and that still had the 3 flashes?
So am just wondering do you know the solution to this?
Could the new battery not be working even though its brand new, or could it be I need a new adaptor as it may have been over used because of the battery not being so good lately? There has been no other problems with the laptop until this.
Hope you can reply soon as I'm really unsure what to do.
