lol... scared me...i thought will be harmful... haha.. since i so sayang my A42JV的。。。XD

everytime i switch on my laptop when it shut down due to no batt it will ask whether to startup windows normally or safe mode.. so i think if you use the laptop till no batt it will cause sudden shut down, just like you switch off the plug of your desktop which is harmful i guess?

but my one is just ask me resuming windows...
ur one only happen when u on the windows and suddenly put out AC or battery...

sure it will harmful n corrupt ur data..

He never expected such a thing to happen. Just pity him.

well, if u are on the window, suddenly the power out, nothing will lost even the microsoft word u are doing, it will auto recover back.(window 7 did a good job, no more window XP)
but if u are starting ur window, suddenly pull out ac or power off,this will lead to system failure.

I noticed Win7 hibernation and resume function having bugs in it. XP does not have this resume bugs. Vista resume is slow but if not mistaken, does not have Win7 resume bugs.

I have tested on diff notebooks / netbooks..all having problem resuming windows back to working condition. After resume back, it does not restore back original desktop setting and the whole system become slows. Even on high end notebook like A42Ja with 6GB RAM.

One thing I notice too. Recent years notebook (HP and Asus that I'm using) does not keep on charging battery. Once the battery is full, it will stop charging. It will start charing once the battery level drop below 95%.

I have an old HP notebook, DV5000 series. After 4 years, battery still can last 1 hour if not mistaken (need to test it out again to confirm). I never take out the battery and the AC adaptor always connect to the notebook.

The question is the battery quality..how good/long it can holding the power before drop below 95%.

Nowadays most of the laptop using lithium cell, so it will discharge itself even though u didnt plug in the battery or use thr battery. So the 95% u mention is depends on how many xell battery or the maximum capacity of the battery. Is dependent variable, which we can give a constant answer.

Where ur laptop a42ja isnt high end laptpp, just a mainstream. My alienware/ desktop serve me well even i hibernate , after resume the desktop i test the benchmark still working like charm. For the bug i did notice where some of the program cant really working well after hibernate

ok, noted (btw, high end notebook for me (i7 CPU) as my low end notebook (umpc) is pentium mobile CPU)

btw, can you do the following hibernation / resume test?

once the notebook go into hebernation, do not resume immediately. Resume after two days. Let me know if it will resume back and work properly or not. Normally, resume immediately after hibernation does not have problem. It is resume after one or two days hibernation then it give problem. XP does not have such issue as I have one system with dual boot: XP and Win7 and the same programs installed. Btw, i have wireless USB mouse connected to the notebook during hibernation/resume.

but why need to use resumer after two days ??
normally a few hours .. or maximum should wont more then 24 hours...

b'cos sometimes need to be away for one to two days (travel) without using that particular notebook (as I use more than one notebook ).

I never dare to hibernate in the Windows 7. It does not display the progress or whatever is going on. It is just a pure black screen.

My friend had his PC sent back to warranty because his PC automatic hibernate at night and the next day he cannot start his PC. There is not even a BIOS display on his screen.

lol...then u should purchase a MAC book

MAC is too expensive for me....

Just done hibernation for 26 hours, it still working charm ^^
