Dell Latitude E5500 Troubleshooting
Business-grade laptop released in 2009. Model number: Latitude E5500.
- Poor Wireless signal
- Poor Bluetooth signal
- Distorted/ No audio
- Poor Battery life
The device is physically hot to the touch, causing poor performance or random system shutdowns.
Dust and dirt can build up within the system's cooling solution, and can cause overheating. To fix this problem follow the repair guide given to access and remove the fan and use a can of compressed air to blow air through the space between the fan and vent. This will clear dust from the heatsink fins and clear up the exhaust vent.
If the fan spins very loudly for extended periods of time, poor thermal compound or compound application may be interfering with cooling. Follow the replacement guide for the thermal compound. If the material is dry or crusty, it needed to be replaced. After getting the compound of your choice, squeeze a rice-sized blob of compound to the top of the CPU, and reseat the heatsink. Too much will cause the compound to spill over to the motherboard, and can cause damage. Too little can result in poor heat transfer, and therefore, overheating.
If you can't hear the fan spinning but the system is overheating, the fan might be damaged or faulty. Follow the fan replacement guide for the laptop.
Connection to access points is poor, or nonexistent, and results in slow or no access to the network.
Check how far away the device is from the access point or router. The max range of the WiFi signal of the laptop is approximately 125 ft. However, the strength of the signal will drop off the farther the device is until there is no signal and the signal strength depends on the number of walls in the way of the access point. Move the device closer to the access point or move the access point closer to the device for improved signal strength.
If there is no signal at all to any networks, the driver for the device may have either malfunctioned, or is not installed. If you have another computer and a removable storage device, like a flash drive, use that computer and go to this site and download the appropriate wireless driver by checking for the correct part and operating system.
If there is no signal at all, the wireless card may be damaged or otherwise non-working and will need to be replaced.
Connection to Bluetooth devices is poor, or nonexistent, and results in poor to no interaction with the devices.
Check how far away the device is from the access point or router. The max range of the Bluetooth signal of the laptop will vary depending on the device, though most Bluetooth devices will have a range of about 33 ft. However, the strength of the signal will quickly drop off the farther the device is until there is no signal and the signal strength depends on the number of walls in the way of the devices. Move the devices closer together for improved signal strength.
If there is no signal at all to any Bluetooth devices, the driver for the device may have either malfunctioned, or is not installed. If you have another computer and a removable storage device, like a flash drive, use that computer and go to this site and download the appropriate Bluetooth driver by checking for the correct operating system.
If there is no signal at all, the Bluetooth card may be damaged or otherwise nonworking and will need to be replaced.
''The sounds that are desired or expected from the laptop are distorted or no being played at all"
If headphones are being used, the audio can tend to either sound choppy or not be coming through at all, even though the sound plays out loud on the laptops speakers. This could be due to the audio jack being loose. Make sure that the auxiliary cord is fully plugged into the audio jack and that the headphones function properly with another device before searching for a deeper issue.
If you are still having issues will the audio, you may have an the incorrect audio driver. To update your driver, visit this website. Here you can run a system analysis to see which drivers need updating for your device. If you wish to update your audio, scroll down the categories to select 'Audio' and download the update. Follow the given instructions from there to complete the process.
The laptop's battery runs out quicker than expected. Your laptop's battery life should last anywhere from 1.5 hours to a maximum of 6 hours.
If the battery is lasting less than the minimum of 1.5 hours the brightness of the screen could be dimmed to slow the decay of the battery.
If the laptop's brightness is needed and the battery is still draining at at faster rate than intended, the next step would be for the user to turn off antennas controlling WiFi and Bluetooth. Having one or the other (or both) turned off should increase the battery life.
Using programs that heavily use lots of memory, also use lots of power. Closing out programs such as graphic intensive games and web browsers with many tabs open should increase the life of the battery.
