Three notebook repair in Nov.2012

1. DELL Inspiron
29/Oct/2012
"HDD not found"
Cannot boot the system

Dell's design is quite disgusting, you could only replace the memory from back panel but not HDD.
The HDD is directly fixed on motherboard. After I unmounted the HDD and connect it to my laptop. My laptop could not identify it, totally broken down. The customer said there is no sensitive data in that HDD, no need to do data recovery.

The rests is simple. Buy a brand new HDD, replace the broken one and install OS.

2. Lenovo V460
14/Nov/2012

Overheating issue. Auto-reboot when playing 3D games.
CPU standby Temp = 70 C
When doing pressure testing, both CPU & GPU Temp > 99 C
2 or 3 seconds later, system frozen, no response and then reboot.

Because of the heat pipe radiator is embedded on motherboard, I must disassemble the machine.

Clean and reapply thermal grease.

After a Netbook dropped down (Part II)

After 10 days waiting, the new LCD panel arrived.

Panel open box.

Model:

CLAA102NA2CCN

Front view

Old & New

Old & New

Move and install the bracket from old screen to new one.

Reconnect the cable.

Done.

After a Netbook dropped down (screen and HDD)

This netbook, from my friend, dropped from the table. The screen cracked and seems always auto-reboot.

Samsung NP-NC10, Intel Atom Netbook
Atom N270 1.6GHz
Intel 945GSE+ICH7-M
1GB DDR2
160G
10.2 inch LED backlight
1024 x 600

Firstly, disassemble the plastic framework.

Separate the LCD panel.

Now we can see the LCD model number and bar code.

Model: BA96-04004A

However, there is only 10 results on Google (maybe Samsung internal model) and all of them are located in Europe, €250 EUR. So far and expensive.

No problem, we could connect external monitor and install Everest AIDA to check the real screen model.

BUT.....

The system could not boot to Windows. Always auto-reboot. No response on Ctrl-Alt-Del. HDD damaged??

Plan B. Switch the HDD to my own laptop, in order to check the HDD and install the new Windows.

Netbook(back)

FUJITSU

My notebook (ASUS)

Check the HDD, all green, no damage. Good.

The reason of infinite rebooting is "windows is missing boot file".

Backup, format and re-install Windows.

[Important] During Windows installation, there is an auto reboot. Before this reboot, the setup.exe restore the *.wim dump file to target HDD partition. After reboot the system, setup will continue but this time, start configuration based on the hardware.

So I need to switch the HDD back to Samsung netbook when the first reboot occurs. Otherwise, the Windows will configured as the hardware of my laptop, nor Samsung. Wrong hardware configuration will lead to BSOD.

After install Windows, I could use external monitor.

Finally, got the real model:

Chunghua CLAA102NA0A

Chunghua CLAA102NA0A

Go eBay and make an order.
