Ok.... heres my situation... i had to replace my hdd in my laptop and now windows will not recognize my battery... I did a full format of the new hdd and a clean install of windows 7 ultimate.... The installation went fine untill i did final reboot (to finish setup) and now my battery icon has an x on it and says "no battery detected" it was fine directly before the hdd upgrade.

i have proper voltage on the battery contacts and the motherboard contacts.

BiOS is up to date
All my drivers are up to date...
Device manager shows the battery controller is up to date and working properly...

Since i have already opened the case to upgrade the RAM ... warranty is void

it is an ASUS x401u less than 2 months "off the shelf" (from walmart) {gulp}

Try something simple real quick, power off, unplug from the wall, remove the battery, and hold down the power button for 30 seconds, wait about a few minutes, and try and power on with just the battery, wait till windows boots, then plug in the power cord.

If that doesn't work, power down again, remove battery and unplug, power on with the battery removed, once windows it booted, pop in the battery and see if that helps..

Also make sure you didn't bend a battery contact and that 2 contacts are going into one slot on the battery..

Or "until i did final reboot (to finish setup) and now my battery icon has an x on it and says "no battery detected" it was fine directly before the hdd upgrade."

Sometimes windows updates will update a driver without you knowing even when you have installed the drivers, I would reinstall the drivers, especially the chipset driver.

Thanx sat..... Well the contacts are ok.... I tried discharging the circuit (holding down the power button etc) tried snapping the batt back in while powered on..... No luck..... When i stop driving for the day i will get the latest amd chipset (thanx for that too ) since mine does not match that one (its a bit older ) .....

Your Always welcome bro, hope it works

Your Always welcome bro, hope it works

I just wondering how i missed that one the build date on my chipset is 4 month prior to the one you put up here.... Guess i got in a hurry....

My biggest worry is i borked something on the MOBO.... Even tho i use wrist straps, rubber floor, grounded workstation, completly discharge everything before working etc etc

It's Windows, it wasn't your fault, it just does what it want's to ... If that doesn't fix it, uninstall all Microsoft Products, and install Linux

I probably should.... Since i got (finally) my trucking software to work in virtual i should run windoze only in a box....
And i do more in linux anyway (even my windoze batch files)

Well.... I updated chipset.... Still a no go ... I am convinced now that it may be hardware..... BIOS wont see the battery now.... And the led flashes red even when powered off... Which seems strange because like i said earlier, i have 12v across the battery terminals AND the terminals on the MOBO..... (i even cussed it repeatedly LOL) still didnt work.....

I think its the battery, the laptop shouldn't supply the on and off for charge (example: 12v) until it receives a signal from the battery that it needs for charging (so you may not get voltage), this is sort of a energy/fault thing if I can remember correctly. The battery also has a board (eeprom, etc) in it that checks if the pack are ok to accept the required voltage for the charge per bank, these are also safety points I believe that were also required to make sure the battery did not overheat and or explode.. Another point to look at is that I have seen this issue also with a battery/laptop that wasn't getting enough voltage from the charger and or a defective one.. note: Some Dells will tell you this on boot within the bios msg..

Hope all this info helps and makes sense.. You can also check a laptops safe points and watch it shut off (NOT Recommended) when you cross even a simple usb cable at points where it shorts. it should turn off the laptop and require you to unplug from the wall and remove the battery until it will self check itself and recheck for a short until its gone, before it turns on and applies power to the motherboard..

I really hope any of this info helps you diagnose.. I really think its coincidence or maybe check a ground or the wrong screw pushing on the wrong area from the cover you removed?

[johnthehillbilly]

Thanx bro...... I will probably open it back up tomorrow and check everything again.... I could have easily overlooked a pinched feed wire or one of asus's foil "shields" contacting the board ..... It has to be something simple ..... If all else fails.... I will just install a u.p.s and remove the battery all together.... (since essentially that is what the battery is anyway)...

I'll also give you one example of a board that has a Tsop and or eeprom that will tell the system the batteries are not new... This hack I have used many of times on APC battery backup units.. Anyways long story short, these battery backups will do this for both sell points for replacements aka swap programs, and or to make sure the company doesn't burn up your home from the battery overcharges and or defective devices.

You can change these values on the boards with a simple COM cable while using the old telnet in windows to connect to it and change the values.. Once done, your backup battery will last the expected 15-30+ min (depending on the load of course) rather than it lasting 5-10 min before it thinks its at full discharge..

Please for anyone else reading this, please don't try this unless you know 100% you know what your doing and you are using brand new batteries.. I am not responsible if you ignore this warning.. This is info only..

Cool.... .... Telnet.... Aint heard that one in a while .... Does it still exist in windows 7 or should i revert to my ancient win95-2000 for that?

LOL, yeah it will work with windows 7.. I know its a lot of info, I take things apart a lot I'm weird like that

Lol... That aint weird.... I dont own anything (that i can think of) that i have not taken apart.....what may be weird is I do most of it here in my truck (so when i am at home i can just hang out with the wife and kids).... so at any given time i may have computer parts scattered out on my bunk and passenger seat etc.... I have even set up a soldering station in the truck lol....

Awesome!

[johnthehillbilly]

So tonight i once again take on the task of opening my laptop(the easy part) to try to find the cause of my battery issues (the hard part) ..... Except i am going to take pics of each section of the MOBO and my test readings.....so if i cannot solve the issue, maybe another set of eyes can catch something i missed........

I'm out of the loop but does windows still have "Power options" on laptops?

Yes...... and it showing "battery not detected"

So i cant change any options (right now)

[tmyinc]

Turn off the laptop. Put battery in and plug in AC. Turn it on and let it boot. Open power options and then remove the battery for a few minutes. Then put the battery back in.
