Laptop Power Up Hang, Fail, No BIOS Boot?

My Lenovo G500s got problem with power on. When I push the power switch, I can see the webcam indicator light power on, and usually, it light up for a while, then light off, then CMOS loading/boot. But the problem is, webcam indicator LED light up, then nothing happens after that.

After some googling (thanks to Google), the problem is related to CMOS memory battery, means the CMOS need to reset. And also, you may need to change the CMOS battery. But for a while, you can open the laptop cover (unscrew it), then take off/out the battery, then reassemble back the cover, then now try power on your laptop.

Maybe at first the problem still the same, stuck at webcam indicator light on. Don't worry, try push the power button and hold until webcam indicator light off. Then release the button. Then push the button again to power on.

So the problem is related to CMOS memory, maybe somehow corrupt or, I don't know. I just know that the CMOS memory need to be reset. So the keyword is "CMOS reset" or "clear CMOS".

VisualBoyAdvance Pokemon Emerald Blank Screen Load ROM?

Been awhile since my last time playing GameBoy Advance (GBA). Year 2000+ I have experienced playing the real GBA. Nowadays, I just play GBA using VisualBoyAdvance on Windows 10 and this software works perfectly!

But there is an error when you load Pokemon Emerald ROM. I have googled the error and found the solution here (http://ngemu.com/threads/pokemon-emerald-white-screen.185305/). What a surprise that it just simple fix/solution, just change the Save Type > Flash 128K, then the ROM now load successfully.


I downloaded my GBA ROM from EmuParadise.Me (https://www.emuparadise.me/Nintendo_Gameboy_Advance_ROMs/31). Have fun!

Want To Update DVD Drive ROM Writer Firmware?

Do you sometimes got problem with DVD you are burning with? Keep getting error or stuck in the middle of the burning process? Or even stuck at earlier process, maybe 1%, 9%, or even half of process? This problem or error usually occured for some type or DVD brand. Here is my solution.

It even my first time to know that we can actually update our DVD Drive ROM Writer. First of all, you need to identify what model is your DVD Writer. I use Nero Burning ROM to burn my DVD. So, at the recorder selection, you can see what model your DVD Writer is. You can either see it when you open the Nero Burning ROM and select New Compilation, or go to menu Recorder > Choose Recorder.



At menu Recorder > Choose Recoder, you can view the current firmware revision of your DVD Writer. So now, is that the latest firmware you got there? To find the answer, take note the model of the DVD Writer. Now, go to www.firmwarehq.com. Mine is ihas324. So I search for ihas324. My previous firmware revision is W, and the latest is Y. So I download the ihas324 Y (BL1Y firmware).



Remove any CD or DVD in the DVD Writer, then start the firmware update. After done, restart your computer. BUT WAIT! My DVD Writer is not working after the update. I can not eject it, not responding. If you have problem like me, here is my solution. First, shutdown the PC, turn of the power plug. Then I change the SATA port for my DVD Writer on the motherboard, change to other available slot. Remove the power cable for DVD Writer, and put it back. Then after that, I turn on my computer, and now, its working perfectly!

Hope this article will help you all. Please take note that this my experience and my way on solving this problem. If you want to try, do it at your own risk. Just be careful.

Dead Lenovo A850, Not Detected When Connected To PC

I have done FORMAT + DOWNLOAD A850 ROW rom to my Lenovo A850. But sadly, it is the wrong firmware. Supposed I need to select CN rom to my phone. After flashed ROW rom, the phone is dead = not detected by PC when connected with USB cable, no boot up.

So, I googled for solution, and found out with this link.

2) http://forum.gsmhosting.com/vbb/f672/lenovo-a850-dead-boot-how-easy-jtag-1868940/index2.html#post11469369

So, my solution based on those links is:-

2) Press VOLUME UP + VOLUME DOWN while connecting USB cable to PC and phone.

Now the phone is detected by PC and I can flash another rom then.
