I used it as a brand new out of the box nearly 2 months. So I think the battery meter already the recharged and consumption curves.

Is there any method that I could isolate and identified whether the problem come from battery, mother board or any hardware related issue? Thank for your comment!!!

Yeah, replace one piece of hardware, like the battery, and watch what happens.

charge the battery, remove it from the laptop for a few days, put it back in. That'll see if the battery is bad or something in the laptop is draining power.

How did it come configured out of the box? It is possible that Sony has enabled wake on lan, bluetooth, etc, so these features are using battery power even though the laptop is "off".

The battery should just slide/snap in. You may need to release the lock(s), these will be slides as well. The laptop should run fine from the charger w/o the battery installed. If fact that is the recommended way to use if it is going to be powered from the charger all the time.
This would be the definitive test. If it loses 30% after 3 days in the frig, you definately have an internal short in the battery & should not continue to use it.

are you sure that it`s not a operating system eror?!!
i`ve seen it on some vista based laptops too 
it`s Bcuz in vista the red botten that has the logo of shutdown just takes takes it on sleep mode !!!
if you have vista operating system ... might the same problem

Yes, I'm sure that I'm shutdown, not sleep mode. Because I already properly choose shutdown from the drop down menu.

On my XP Desktop system and too lazy to go to the car andd get my laptop so my instructions maybe out of sorts. But to shutdown Vista, click the Start Button then look to the bottom right of the menu, you will see an arrow head pointing to the right, click it and select shutdown from the fly out menu. Any other method from the menu I believe just puts in in sleep/suspend.

Just set up a laptop to dual boot XP/Linux. Everything went well after the third or fourth try. (I am not an M$ fan, but Linux still has a few things to learn about documentation/ease of use).
Linux side works fine, good connectivity with wireless card to any available access point. So back to the XP side & oops – no wireless connection.
Go to View networks and no networks found. Hmmm…
Fire up netstumbler and it finds 6 available networks and the card connects to the last used AP.
Back to View Networks & still no networks found.
I am thinking perhaps the Linux drivers have put the card in a mode that is not recognized by Windows.
Re-booted - no change. Powered down – no change.
Reinstalled windows network drivers, turned off Zero Config. Turned zero config back on.
Still no available networks viewed and card will not connect (until Netstumbler is run).
This lappie has XP SR3 and an internal Intel 2200 wireless card.
Can anyone offer an idea what is going on?
Thanks!
Update: Cured by reinstalling Windows. But still curious if anyone else has seen this, a web search did not turn up a solution.

I am sorry for the spam,I find the people come here are mostly the specialist on software,my company want to develop a Java SDK for our product,seems not so many software designers understand our products,so maybe any one can give me a reference about what the cost will be to develop a Java SDK for our UHF RFID Reader?

hi
i am new for the usb device driver coding. i dont know how to start writing the usb device driver coding.
we developed the embedded device(POS). we have to retrive the data from POS device to PC through USB. to communicate with the PC i have to develop the driver.
i am going to develop the driver in VB.net or C#.i am expecting some sample codings regarding usb device driver.
please help me out. thanking you

Oh you're expecting sample code, are you? Have you tried a Google search, or looking at books at all?

You're not going to find any examples of writing a device driver in VB.NET or C#. You'll find tons of them in C++ though.

Not really. You might find a few in C++ but since Microsoft dont support C++ in the kernel you will find almost all driver code in C.

Drivers are c/c++, with the former preferred due to its stricter controls over memory layout.

Assuming htis is for windows XP or later you need to lok at KMDF. It is a wrapper around WDM which makes life a lot easier for beginners, although if you want to feel serious pain, then go for WDM.
If its for 2k, NT4, or Millenium/98 you need to use WDM. If its for 95 then you need a DOS style driver.
If its for Linux (not my field) you need to use their kernel API.
Mac, dont know. I heard it had a Unix OS these days, so perhaps its the same.
Relevant books are:
1) KMDF, dont know, but if you can find a book by Walter Oney, its the one to get.
2) WDM, anmything by Walter Oney.
3) Linux, O'Reiley books are the standard.
(Many of these books, or for windows the DDk/WDK come with sample code.)
I can develop the entire driver for your company. This could be a better financial proposition and deffinitely a better time wise proposition since it will probably take you about a year to develop a basic driver whereas I could have one finished in a few months.

Hi, I have a problem with my flash drive JetFlash High Speed 185[^]with a capacity 2Gb. I just bought and used it for one month and this morning it start to have a problem. The problem is when I try to copy the file to the flash drive it display the message box that the flash drive is write protected. Its require me to disable write protected in order to copy the file. But I already check it that my physical flash drives do not contain any switch or button to turn on or turn off the write protected feature. I also check the configuration flash drive property in my computer and I didn’t found any configuration that set it as a write protected flash drive too. Now I could not copy any document into it but I could copy it content out to my computer.
If anyone knows the solution to fix the problem please let me know. Thank in advance!!!

i have seen this problem on mac & linux based pcs that occures because mac and linux don`t support NTFS file system !
if you have a mac you can buy a tiny software named ntfs for mac that runs ntfs file formats for it.
but if you don`t mind buying or have linux it`s better to change its format to fat !!!
it really works !

|

Newer linux distros should have native read/write support for NTFS, read only support has been available for years.

My flash drive is originally formatted with FAT system. Now I change it because I want any headache with it anymore. Thank you very much for your comment.

Hi,
I have the following scenario. I have an SDIO client driver developed by Arasan which allows me to access the SDIO card as virtual COM port and the SDIO card is connected to a peripheral which has Arasan Chip which converts SDIO to UART.
The platform I am using is HP 211 running Windows Mobile 6.
When I insert the card, the OS detects it and loads the client driver.
But I have a problem if the card is already inserted and the PDA is reset. When the PDA is rebooted with the SDIO card inside it the OS does not load the client driver.
My question is: how can I load the driver programatically using VC++.
The registry entry for the driver is:
[HKEY_LOCAL_MACHINE\Drivers\Active\62]
"Hnd"=dword:00d26a80
"Name"="NDL1:"
"Key"="\\Drivers\\SDCARD\\ClientDrivers\\Custom\\MANF-02DF-CARDID-9103-FUNC-1"
"BusParent"=dword:001f8270
"InterfaceType"=dword:00000000
"BusName"="SDBus_0_0_1"
"ClientInfo"=dword:00d38520
I would greatly appreciate your help.
Thanks!
