Updating memory on hp presario laptop
Be careful, there is a thin ribbon cable running from the switch cover to the motherboard. Now you can lift up the top side of the keyboard and access the connector underneath the keyboard. Carefully lift up and remove the top cover assembly. The keyboard cable connector is located above the touch pad.
In this guide I explain how to disassemble a Compaq Presario F700 notebook.
Before you can remove the keyboard, you’ll have to unlock the connector and release the cable.
On the following photo the connector shown in the unlocked position.
You can set up your laptop to go to a hibernation mode or to a standby mode when the LCD is closed. These modes are triggered when the display is closed and the lid close switch is pressed down.
If the LCD screen on your laptop will not light up when you open the display assembly, check the lid close switch is stuck inside (it might happen because the switch is dirty).
If you know more models, please mention them in comments after this post. I didn’t really believe that this trick might work and tried it just because of curiosity but… I closed it in a tablet mode (with hard drive and battery removed), plugged the AC adapter and wrapped the laptop properly in bubble wrap. I just couldn’t stop and tried the fix on another one. It was running like that for about 60-70 minutes but then I noticed that all LED lights went off. Maybe the motherboard overheated too much and shut down on its own.
