Today I will remove and replace a damaged keyboard on a Dell Inspiron 1525 laptop. I’m replacing the keyboard because my customer spilled soda on it and all keys are sticky. If you need a new keyboard for your Dell Inspiron 1525 laptop you can find it here for less than $20.
In this post I explain how to replace or upgrade memory (aka RAM) in a Dell Latitude D830 notebook. Also, these instructions should work for a Dell Latitude D820 notebooks and maybe some other models. Please mention you notebook model in the comments if this guide works for you.
You can check the amount of installed memory in the BIOS setup menu. As you see, in my laptop I have 1024MB (or 1GB) memory installed.
Dell Latitude D830 notebook requires DDR2 memory modules. You should use PC2-5300 SODIMM memory which runs at 667MHz.You can use same memory type for a Latitude D820 notebook too.
Dell Latitude D820/D830 can take up to 4GB memory total. You can install up to 2GB memory in each slot (there are two slots available).
In a Dell Latitude D500 laptop the power jack is soldered to the motherboard. If the laptop loses power intermittently when you wiggle the power plug, most likely the power jack is damaged and has to be repaired. In order to repair the power jack you’ll have to remove the motherboard.
In one of the previous posts I explained how to remove the motherboard from a Dell Latitude D500 but it came out mounted to a metal bracket. You cannot access and repair the power jack while the motherboard is mounted to the metal bracket, it has to be removed first.
OK, let’s prepare the motherboard for the power jack repair.
In this guide I explain how to remove and replace the motherboard in a Dell Latitude D500 laptop. Also, you’ll see how to access and replace all other internal parts in this laptop.
I had two different problems with the laptop.
1. The power jack was damaged. I could have just resoldered the jack but the second problem was more serious.
2. The motherboard couldn’t charge a known good battery. Apparently it had a problem with the battery charging circuit.
So I decided to replace the motherboard.
This guide will help you replace the screen inverter in a Dell Latitude D800 laptop. As in most other models, the inverter board is mounted inside the display panel and located below the LCD screen.
You will find the display panel diagram in the service manual for Dell Latitude D800.
Screen inverter failure symptoms:
1. The laptop starts normally and video works fine for a while but after some time the screen goes very dark. You still can see the desktop but it’s very faint.
2. When you turn on the laptop, the screen lights up for a moment and goes off.
3. You can light up the screen for a short period of time by pressing on the lid close switch.

If your Dell Latitude D820 laptop runs very hot and noisy, most likely it’s time to clean or even replace the cooling fan. Thanks to Bite my bytes for the picture and some instructions.
The cooling fan in this model is buried deep inside the laptop so be ready to take the whole thing apart. This is not for beginners.
Here are a few typical cooling module related problems:
Is it possible to upgrade the processor in a Dell Vostro 1500 laptop? Apparently it is, check out this post. MikeT was able to upgrade his laptop from Intel Celeron M540 processor to Intel Penryn T9300.
I would assume that this upgrade could work for Inspiron 1500/1521 witch is the same laptop with a different name.
In order to remove and replace the processor you’ll have to disassembly the whole laptop, there is no easy access from the bottom. The processor is hidden inside the laptop under the heat sink.

Turn off the laptop, unplug the power adapter and remove the battery.
On the bottom of the laptop you’ll find four screws with a letter “K” witch means keyboard. Remove all four screws.
