Compaq Presario CQ50 Labtop, makes awful constant beeps
A day ago my Compaq Presario CQ50 labtop, stopped working. When i try to start it up it makes a constant awfully loud beeping noise and nothing appears on the screen, the fan doesn't run anything, Before this problem occurred i was updating it's features for something i think were along the lines of Win flash, then my screen froze except for media that was playing at the time and the keyboard and mouse sensor wouldn't respond. Before i had over heating problems but the computer simply shut itself down if it happened. I've taken out the battery and tried to reboot it but the problem still occurs. Any advice would be appreciated.

hi Im Kapila from Sri Lanka. to solve the noise like a siren, open the sound mixer (double click on the speaker icon on the task bar) and mute the mic on that, or decreas the mic level. its OK, you can adjust it the audio settings perfectly via double click on the audio icon in control panel. not enough the details for flickering problem. send the message to firstname.lastname@example.org regarding that
1 disconnect the AC adapter and remove the battery from the laptop
2. Press and hold the power button for 30 seconds
3. replace the battery and connect the ac adapter to the laptop
4. turn On the notebook and check.
If the issue persists, restart the notebook and press F10 to check if you see the BIOS screen. If you cannot see the BIOS screen then the issue could be hardware issue and your laptop needs to be repaired
I could well be wrong, but my gut feeling is that your laptop is having memory issues. Start by accessing the memory and (carefully) removing it from its seating. Give it a quick check for dirt / dust etc and then re-seat it. If you have multiple memory modules, try swapping them round. Replace all covers and then restart the computer. Hopefully it's as simple as that. If not, you may need new memory, or alternatively the beep codes for your laptop refer to something different.
If you can get some Compaq support online, check that out for a dagnosis of the beep codes. That might point you in the right direction, assuming the above attempted solution is of no use.
When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.
Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.
Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.
Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.
