Asus = ECS ?
After reading all the posts, I would like to add my own experiences with the Z71V battery issue, and for comparisons:
- Owned Z71V for over 2 months+ before the charge light decided to stay on 24/7
- Indicates charge capacity anywhere from 30-100% and still charging
- Tried cycling battery as per BIOS settings (as suggested by my dealer/reseller), resulting is a noticeable drop in battery performance level afterwards
- Once main battery drains low and switches automatically to the modular battery, charging rates and levels are affected across both batteries, and are stuck at 30-60% charging levels until the main battery is removed, then modular charges back to full 100% capacity and light indicator turns off!
-Tried running off main battery (showing 100% charged), but within 35mins of running on "Battery Saving Mode" the notebook shut down due to low/dead battery levels! After that I had enough and RMA'd it back to place of notebook purchase....
- Over one week since main battery RMA'd through dealer/reseller (at the time of returning battery, there was another Z71V on their bench with the window showing its battery level!)
Now here's something I have not heard anyone mention through this thread (nor did I find reference to it in other threads on the net):
The battery issues appear to be the same problems which afflicted certain ECS notebooks a while back....ECS had a serious problem with their notebooks, showing the same problems/symptoms such as trouble charging & battery levels etc.
Here's the real kicker:
The ECS owned division which manufactured the notebook & batteries for those ECS notebooks (which were affected) were sold off to....you guessed it, ASUS about a 2 years ago.....sheer coincidence? I think not, not now at least...read blurb about the Asustek / ECS deal here
I work in a large national PC Distribution company which still has direct ties to ECS, so I was informed of this battery connection (no pun intended
) recently when I mentioned my Z71V main battery troubles to some co-workers! ECS confirmed that their notebook division was sold to Asus.......
Could it be that when ECS sold off their troubled notebook & battery division to Asus, that the defective designs were never corrected, or had Asus known of this issue prior to them purchasing it from ECS?
Either way it looks like its the same problems now happening to most of the Z71V owners and their main batteries, the same troubles that ECS owners experienced in the recent past....
Did you know that certain current model ECS notebooks also have the 100/133 Dip switch feature as our Z71V? I'm afraid to think of what else might be common in similarities...damn
Asus = ECS
Could the Z71V actually have been developed by the old ECS engineers, explaining the battery/charging issues, and the major differences between the Z71V design/features compared to the other Asus notebooks?
