Dell Inspiron 8500 :: CPU Run At Half Speed
Feb 26, 2011
I have two apparently identical Inspiron 8500's. Intel Pentium 4-Mrated @ 2.4 Ghz.
One runs at 2.4 Ghz as shown in system properties, CPU-Z and other utilities.
The other runs at only 1.196 Ghz max, shows 1.196 Ghz in BIOS. Bios version A08 apparently the latest offered.
I've tried swapping batteries, power supplies and cooling fans. The fans and grills are clean, and the BIOS proves this isn't an issue of temperature or something that changes after bootup. I've installed speed switch XP, which also shows 1.196Ghz and nothing can be set in that program that changes it either.
I've downloaded the "Speedstep" software update from Dell ... no solutions there. It doesn't step down or up, just runs at max of 1.196 Ghz, which is of course noticeably slower than its twin.

was running xp pro. I have wiped the hard drive and will be installing win xp pro on it.I only know noticed, in bios, that it says the cpu is running at 800 mhz and not at its proper speed of 1.73 ghz. In the bios i set it to default settings and saved it but no luck there. The bios is A06 from 2005 but i have a friend who has the very same laptop and his is running at the correct speed of 1.73 and he has the same bios so i dont thing that is the issue.

With all software issues decided as not the problem, I am trying to decide what piece of hardware needs replacing or is even fixable.
The Dell when first turned on looks like a tetris screen, lots of vertical lines and some horizontal, lots of colors. Next boot up will be more lines not as distinct and a white background. This second screen will stay with me through several more power offs, power on.
sometimes I will end up with the BSOD stop code which supposedly is a memory problem but the memory checks okay. Finally when the laptop is really warmed up, it boots normally and will work for the entire day. I removed the bezel and keyboard but have no idea of what is "normal"
If a cable had been evidently loose or cracked, that would have helped but all I see is a sys board which appears to have a slight film on it (normal?) The display cable is wrapped with electrical tape where it goes into the display unit. Is this normal? If anyone has had their 8500 apart and took photos, I'd appreciate access to them.

It came from a library and looks very clean. Booting however indicates problems. Sometimes it will boot to the login screen but mostly there are lots of vertical lines, error messages I can't read, etc.
I was able to get into the BIOS once and I was checking boot order. That seems fine. I tried to get into safe mode several times but was not successful.
Is the presence of those colored lines, bars more indicative of a bad video chip or could it just be a driver problem.

an Inspiron 8500. I have increased the memory to 2Gb, added a wireless N card and put in a 160Gb HD. It runs Win 7 RC ok with it's Mobility Radeon 9000 32mb but was thinking of putting in a 9600 128mb.
My question is if you're not going to be doing any gaming is the heat sink mod mandatory to use the 9600 in the i8500? Looking mainly to use some of the Win 7 eye candy features. Found a place on the net selling new (supposedly) 9600's for $100, which is what used ones go for on Ebay.

does anybody know if there is some way to set F1 to F6 as function keys and F7 to F12 as multimedia keys at the same time?
This would solve all my problems as I only really use F1 to F6 in windows and would like to be able to use the multimedia keys at the same time without having to change the function key behaviour in windows mobility center.
The only options so far are to set the entire function key row to either multimedia or function key first

Long time no see! I'm about to grab a Inspiron 1521 for $100, the problem is in the title. Run's fine, for a half an hour then shuts off.
My assumption is the maximum problems could be:
- Fans not working, resulting in an overheating: hence shutdown at max temp.
- Heatsinks or thermal compound issues, resulting in an overheating: hence shutdown at max temp.
- Rare possibility that it has a cold solder somewhere located in the mobo: hence shutdown after 30 minutes of running, generated heat build up .....

I have this system running on Win 8.1; The touchpad is possessed. It moves and click on its own half the time. I've upgraded the drivers to the latest 4/01/14 release but to no avail. I've even restored the system but the result is the same.
Steps I've tried which took nearly 50+ hours to do:
1) restore, uninstall dell drivers, update to newest drivers;
2) restore, and update to newest drivers over existing drivers (included in the restore)
3) performed steps 1 & 2 with and without WOW64
I've been having to use the mouse to save me from this, however, the touchpad still takes over and moves the cursor on its own, though less frequent.

Laptop 3 years old and touchpad slowly stopped responding one night.
Downloaded new driver (ALPS Touchpad v7.1007.115.102. A05) no less than 3 times and had a partial success. Now right half of touchpad is ok but left half can only respond to up/down finger movements.
Run Dell diagnostics and all hardware is ok.
Run a full antiVirus scan and ok. Laptop says new driver is ok and running ok.
Touchpad does not work in BIOS and done a full diagnostic check and said the touchpad is fine!
Use of mouse is ok so not the end of the world!
Back to factory settings?

I just upgraded to 4gb RAM on my 1521 from 2gb. After I installed it I checkethe <Properties> on XP to see if all the RAM was showing up, 3.37gb showed up. But I noticed the processor speed was down to only 795mhz, so I checked it with CPU-Z again and that read 795mhz as well.
I went into BIOS and turned off the AMD PowerNow option and it bumped it back to 1.9ghz. I ran CPU-Z again and it was at like 1.895.2ghz, but i noticed the bus speed was down to 199.5 mhz. Shouldn't that be like 333 or something? I've attached some screenshots from CPU-Z after turning off AMD PowerNow, with PowerNow all cpu specs are much lower.

I'm running stock 2x 512 mb 533 Mhz ram right now.
I would like to upgrade but I can't find information about my motherboard ANYWHERE. It's not listed on the dell system specs website, either.
So, my question comes down to which would be better:
PC-5300 (667Mhz) ram with 4-4-4-12 timing or PC-6400 ram (800Mhz) with 5-5-5-18 timing?
What is the maximum speed of memory that the e1505 can use? If it's 667 Mhz, I'm of course going to go for the ram with faster timing, but if it's 800 Mhz then I'll go for the speed. I'm using a 2.0 GHz core 2 if it matters, and all I could find it bios is that it's a mm061 "system

I have a 1520, 2Ghz Duo, 2.5 Gb Ram, running XP.....I also have a Line6 Guitarport USB audio interface. When I use this the audio often drops out a lot, especially when acessing the hard drive - what can I do about this? -
it's a 5400RPM drive - will upgrading to a 7200RPM improve things? It seems something is effecting the USB data stream.
The hard drive I have is a WDC WD1200BEVS-75UST 120GB
Also, is the drive running in SATA mode - when using HD tune it says:
Standard: ATA/ATAPI-8 - SATA I
Supported: UDMA Mode 6 / ATA/133
Active: UDMA MODE 5 ATA/100

I've downgraded my Inspiron 1420 recently to XP SP3 with all the device drivers properly installed. Everything seems works fine except that I found fan1 & fan2 always on at max. high speed (very noisy) and CPU always max. at 1.5GHz (seems lost SpeedStep control, checked enabled in BIOS, with SpeedStep control cpu speed should drop to lower rate while the notebook is idle), the fans and cpu speed status are checked via the utility program I8KFANGUI.
If I enabled automatically temperature control in I8KFANGUI then fan1 can turn off as cpu cool down to below 55c and only turn on at Low speed at 60c (still very quiet, noise no noticeable) but still fan2 is always high at 4XX RPM constant rate, I8KFANGUI in fact reported fan2 is not controllable even for just turn on and off .....

I recently downloaded A06 version of the Dell Inspiron 15r 5521 bios, and I was wondering if (and how) it is possible to change the fan speeds and temperatures for my system. I can't find any option for this.
I use F2 to reach the Setup bios interface.

i have encountered another bug aside from gpu boost issue, which is currently still unresolved. Fan speed control is not going idle on 7720 SE, even when temps are very low (below 40c)... on A12 BIOS, I have to restart my laptop to be able to switch to FAN Idle speed again. These are temps iam having and fans are still on.

Just purchased new Dell Inspiron 15 (3521). Wireless will only connect at 72Mbps. After some googling found this is by design. The adapter is the Dell Wireless 1703 Adapter. Can Dell pls confirm this is the case and that there is no way to achieve TRUE wireless N speeds ? The fact that this limitation is not advertised on any product material/brochure/sales rep is a concern. Would Dell replace the adapter with one capable of proper wireless N speeds free of charge ?

I have a pretty good amount of knowledge behind computer software, and hardware operations. I am aware of the fact that the fan will increase speed according to increased temperature of CPU, and other components. However, is the fan supposed to periodically, turn on and off, each occurrence running at full speed for 10-20 seconds, then shut off again? How about the same question, when the laptop is physically(meaning you can feel it) hot? I don't think that this is a hardware issue. I've recently had a hard drive fail on me, and had another hard drive(same exact model hard drive) installed, and Windows 8 reinstalled. I think somewhere along the lines of the OS reinstallation process, some drivers were probably missed and this might be causing the issue. On the other hand, the fan in this laptop is the same one from the factory, which makes it 4 years old. What is the lifetime on the fans in the Inspiron N7110?

Last month I got a Inspiron 3520 for my daughter and have had nothing but trouble with it. When I plug it in to the router I get download speeds of 35-45 mbps, when I check speed using the wireless connection they range from 11 mbps down to less than 1! It is not the drivers, the power settings, the router as I have followed all of the "fixes" suggested in other threads and run through a 2 hour session with the Dell online chat rep which ended when he had to reboot the machine and the link to return to the chat that he left on my desktop was invalid.
If I move our other HP laptop to the same location (less than 5 feet from the wireless router) that gets download speeds of 25-30 so I am sure it is not the wireless signal. Also we have iPads and smartphones that all work just fine from anywhere in the house. I have tested the Dell speed when there is no one else home and all other devices are turned off and it is terrible. I know this is not a top of the line laptop but I expect it to work at least well enough to be functional. Based on my reading of this and other sites, I am making a guess that the wireless card is faulty.

First of all I have a dead pixel right in the middle of the screen - will be taking this up with Dell tommorrow as its really off putting especially on brand new laptop.
My second issue is with wireless - did have problems initially with wireless disconnects and genrally slow speeds
Im not entirely sure but removing Mcafee seemed to work with the disconnects at least - load of rubbish imo
Now my only other major issue is with wireless speeds on the 1703 card
I seem to max out at about 45mb on all broadband speed tests - while on another laptop I get the full speeds of 80mb on the same server at the same location
Im only getting a link speed of 72Mbps in the networking tab of Task Manager and this does seem rather slow - the other laptop gets 450Mbps (better wireless card - to go with my Asus N66U Router)
Anyway my thought process is that the 1703 wireless card is not up to much - I understand that the 1703 card is wireless and bluetooth - with I think 1 antenna for bluetooth and one for wireless connected to the wireless card.
Now I dont use bluetooth much if at all - so does it make sense to buy just a wireless card and connect the two antennas to the card and therefore losing bluetooth connectivity but gaining better wireless connection
I think I have an Intel Centrino WiFi Ultimate N 6300 in the other laptop

I have a Studio 15 with Dell Wireless 1510N Mini-card.
I noticed that the signal strength of this card is quite bad. I have another Studio with a Intel Wi-Fi Link 5100 and the signal strength is very good.
I did some testing by putting two laptops on the same spot. The Intel card has a signal strength of 94% while the Dell card has only 60%. Is it because the Dell card is faulty or something?

I have a Dell Inspirion 5520 that has Intel(R) Centrino(R) Wireless-N 2230 built in.Also I have a TP link TL-WR740N wireless router.I have an 80Mbps/25MBps internet connection.My Speedtest result with no router:When I connect all these via an Ethernet cable, I get the maximum even through the router:But when I try to do the same with WiFi I get 30/20 Maximum speed, and I'm sitting next to router!I have this configuration:*router:* -

do get the fact that speed through wireless is slower than with wire, but losing 50Mbps is a bit too much!
