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!

How to register a business name

Attending business summits and conferences is a big help to those who belong to the quite "techy" (technological or technical) industry. Being a graduate of one, I had less knowledge in the field of entrepreneurship. Enrolling myself in business administration gave me quite the knowledge to be a part of the business world and thus improve my entrepreneurial skills. I now would like to share this information that I got familiar with (and I managed to get a copy of the entire process from the 6th Mindanao ICT Congress): How to Register a Business Name (in the Philippines) ----------------------------------------------------------------------------------------------- SINGLE PROPRIETORSHIP Applicant must secure 2 copies of registration form and pay Php 300.00 (rate may change) for single proprietorship registration processing fee.

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

Using Firebird with ASP.net

In my previous post , I was able to connect a firebird 2.0 database to asp.net using controls. The next goal was to connect to a firebird database using the firebird.net engine and using the repeater control. I however, was able to use the firebird.net engine to connect to the firebird database but not to the repeater control. I used the html table tag. I've created a simple asp.net demo displaying the contents of a firebird database on page load. Here are the steps: 1. Things Needed: Firebird 2.0 Server Firebird 2.0 Client Visual Web Developer 2. In Visual Web Developer, create a new ASP.net Website (using C# as the programming language). The project will have a default page named Default.aspx. Make sure that the code is separate from the page (ex. Default.aspx.cs is separate from Default.aspx) 3. On the Website menu, click on Add Reference. 4. Select the Firebird - ADO.net 2.0 Data Provider and click Ok. 5. Add using FirebirdSql.Data.FirebirdClient; to the "using" sec
