Notebook does not power on

From your mail, I understand that your Notebook does not Power On.

I will certainly assist you in resolving this issue. This issue could arise due to static charge deposition on the motherboard components.

To resolve the issue, I suggest you to perform the following steps one after the another:

Step 1. Power drain:
1. Shut the computer down.
2. Disconnect the AC adapter and remove the battery.
3. Press the power button down for about 30-60 seconds.
4. Reconnect the AC adapter and the battery.
5. Restart the computer.

Step 2. Try restarting the computer only with the AC power, without the battery and vice-versa. Look for any damage in the AC adapter cable. Sometimes the Power cable gets damaged or battery gets discharged and there is no other option left to boot the computer.

I also suggest you to perform the steps given in the link provided below:

**********************************************************************************
In reviewing your e-mail, I understand that your Compaq Presario F750US Notebook PC is not powering on.

The issue could be due to any of the following reasons:

1. Accumulation of static power.
2. Loose Connection of RAM.
3. Any hardware failure in the motherboard.

In order to isolate and confirm the issue, please perform the following steps:

Step 1: Power Drain

Due to regular use of the notebook, some static charges tend to stay in the computer, and sometimes results in not allowing the computer to function properly.

Please follow the power drain procedure to confirm the same:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30seconds to 1 minute.
4. Put the Battery in.
5. Reconnect the AC adapter.
6. Turn on the Notebook power.
7. Restart the Notebook.

If the Notebook boots up you may fix the battery back. Try restarting the computer only with the AC power, without the battery & vice-versa. If the issue still persists then I request you to reset the memory modules, as sometimes the memory module connection get loose.

Step 2: Reseat RAM

Please visit the below web site to know the removal and replacement steps of RAM:
