Open a Lenovo 3000 G410 Battery

One of the common problems with laptops is the deteriorating performance of its battery. Laptop batteries are made up of Lithium Ion (Li-ion). I have a laptop that is more than a year old. Last week, its battery went totally dead. I'm still looking for a replacement. I'm very careful in finding one because most cheap alternatives are poor in performance (with only 45 mins up time compared to the original 3-4 hours). Some are overly priced. I now have a prospect seller and will be purchasing after this post. Well, to continue, out of my curiosity, I opened the battery. The laptop is a Lenovo 3000 G410. Before my exploration, I took the specifications of the battery. It turned out that it's manufactured by SANYO. Here are the specifications:

Battery name: PABAS024
Unique ID: 3658QSANYO PABAS024
Chemistry: LION

I really don't have any knowledge about the hardware. All I know is that it can be charged and discharged. Despite my limited knowledge, I still opened it up and here's how it looks like:
















There are six (6) cells inside which were all interconnected to a chip that would then be in contact with the laptop. I just don't know where the defect is but I observed that there is somewhat a burned section of the chip. I still need to check the other parts. I need a tester though.

It's really expensive to buy a new one but it's worth the experience. I now know the internals of a laptop battery and I'm on a quest to learn by myself on how to fix a laptop battery or at least how to replace those cells with an equivalent. It's quite dangerous but I'm up for the challenge.

Buy that new Lenovo when you get the casino bonus's baccarat and blackjack game strategy!

Adding a Footer to the DataGridView component

I have been searching for sites and forums that would give me a any hint on having a footer on the .net DataGridView control. It was frustrating. I found some, but not what I was looking for. I use windows forms. It would have been easier if I was into web. I decided to create one for myself. It's not complete, but it works with me. It needs improvement and I hope that some programmers who might pass through this blog will help me with it :D. Limitations: Cannot set Footer values during design time. Can sometimes hide a row when scrolled to the last item in the grid. What I did was just create a user control that inherits the DataGridView control and add a StatusStrip to act as the footer. public partial class MyDataGridView : DataGridView { public StatusStrip Footer { get { return (StatusStrip)this.Controls["Footer"]; } } private bool _footerVisible; [Browsable(false)] /// /// Sets or Gets the va...

How to cheat blog polls

Ok, I really need to post this. Many bloggers put polls on their blog sites and rely heavily on the results that they give and some even draw conclusions based on those data. The problem is that they don't check where the data those polls are generating are stored. Many polls don't even record the voter's information. Well to those of you who want to cheat polls (I mean blog polls. Some polls are really reliable), here are some points: 1. These polls don't store your IP address nor your MAC address, how then do you think are they checking for flying voters? COOKIES! 2. Now you already have an idea. Now try to vote to a blogger's poll then clear your cookies and refresh the page. You'll be able to vote again. 3. If #2 doesn't work, there's a big chance that your voting data is stored on internet temporary files. Now you know what to do. Delete those files. 4. If #3 doesn't work, then your data might have been stored elsewhere. You might want to use a ...

Using Crystal Reports 10 with C#.net and Firebird

C# express doesn't include a report designer or viewer. Reports however, is very much needed when creating a business software. Since C# express doesn't include a report designer, we need to find other means. One is to use a free report such as MyNeoReport. This however may not work under many circumstances. The other alternative would be to use a proven report engine and designer-Crystal Report. Crystal Report has been used by many developers (in our city). However, using a free programming language and IDE, and a free database is very limiting. Not much information can be gathered on the net either (with regards to reporting as of this writing). Here's a way to use Crystal Reports using Firebird database and C# Express as software development IDE: Pre-requisites: C# Express 2005 EMS SQL Manager 2005 for InterBase & Firebird Lite Crystal Reports 10 Create the following database: Name: TestDB1 Tables: TESTTABLE1 Columns:  ID - PK, INTEGER,AUTOINCREMENT DES...
